Bolsonaro mobilizes supporters in Brazil amidst trial for alleged coup plot against Supreme Court | Demonstrations Update

0

Legal woes hang over the former president, who has called for several demonstrations in support of himself in recent months.

Facing serious legal jeopardy with potentially years of incarceration over an alleged coup plot being tried by the nation’s Supreme Court, former Brazilian President Jair Bolsonaro has attended a protest by his supporters.

Around 2,000 people attended the rally on Sunday in Sao Paolo.

On Saturday night, the far-right ex-leader told his followers on the AuriVerde Brasil YouTube channel that “Brazil needs all of us. It’s for freedom, for justice”. He urged supporters to march through Sao Paulo’s Paulista Avenue on Sunday.

“This is a call for us to show strength … this massive presence will give us courage,” he declared.

In February, Bolsonaro, 70, who led the country from 2019 to 2022, was charged with five counts of planning to remain in power and overturn the 2022 election result, which current president, the left-wing Luiz Inacio Lula da Silva, won. Thirty-three of Bolsonaro’s closest allies were also charged.

Earlier this month, Bolsonaro testified for the first time before the nation’s Supreme Court, denying any involvement in the alleged coup plot.

The Supreme Court headquarters in Brasilia was one of the targets of a rioting mob known as “Bolsonaristas” – who raided government buildings in January 2023 as they urged the military to oust President Lula, an insurrection attempt that evoked the supporters of Bolsonaro ally United States President Donald Trump on January 6, 2021.

Police have referred to the demonstration as an uprising and an attempt to force military intervention and depose Lula.

Bolsonaro claims that the various cases against him are politically motivated, aimed at preventing him from making a comeback in the 2026 elections.

Brazil’s Superior Electoral Court ruled last year that due to an abuse of Bolsonaro’s political power and his baseless claims about the country’s electronic voting system, he would be banned from holding office until 2030.

‘An abominable thing’

Earlier this month, at Bolsonaro’s first testimony at the Supreme Court, the former president denied that there was a coup attempt.

“There was never any talk of a coup. A coup is an abominable thing,” Bolsonaro said.

“Brazil couldn’t go through an experience like that. And there was never even the possibility of a coup in my government.”

Bolsonaro was abroad in Florida in the US at the time of this last-gasp effort to keep him in power after the alleged coup planning fizzled. But his opponents have accused him of fomenting the rioting.

At the same time, Brazilian police have called for Bolsonaro to be separately charged with illegal espionage while president.

According to legal experts, the sentencing part of the coup plot case is expected in the second half of the year. If convicted, Bolsonaro could face up to 12 years in prison.

During his legal troubles, the former president has called for several protests, but his appearances at them have declined in recent months, as have the crowds.

According to estimates by the University of Sao Paulo, about 45,000 people took part in the most recent march on Paulista Avenue in April, almost four times fewer than in February.

Sao Paulo Governor Tarcisio de Freitas, a former Bolsonaro minister, is a top candidate to represent the conservatives in the 2026 presidential election.

Israel orders evacuations in northern Gaza amid Trump’s ceasefire push

0

Israel has ordered Palestinians to evacuate from parts of northern Gaza ahead of increased military action, as US President Donald Trump pushes for a ceasefire deal.

People in neighbourhoods across Gaza City and Jabalia have been told to move south towards the coastal area of al-Mawasi as Israeli military operations “intensify and expand westward”.

At least 86 people were killed as the result of Israeli attacks in the 24 hours before midday on Sunday, the Hamas-run health ministry said.

Three children were among those killed in a strike on the so-called “safe zone” of al-Mawasi, their parents said.

Trump has reiterated calls to “make the deal in Gaza” and “get the hostages back”.

On Saturday, Trump had said on Truth Social that Israel’s Prime Minister Benjamin Netanyahu was in the process of negotiating a deal with Hamas “right now”.

Meanwhile, the Israel Defense Forces (IDF) spokesman Avichay Adraee said on Sunday that the Israeli military was operating in north Gaza “to eliminate terrorists and terrorist infrastructure”.

Medics and residents told Reuters that military bombardments increased in Gaza in the early hours of Sunday, destroying several houses.

Gaza’s Hamas-run civil defence agency told news outlets that at least 23 people had been killed on Sunday alone.

Medics said five people were killed in an Israeli air strike on a tent housing displaced people in al-Mawasi near the southern city of Khan Younis – an area where people in the north had been told to evacuate to.

Five members of the Maarouf family, including three children, were killed.

“They bombed us while we were sleeping on the ground,” their mother Iman Abu Maarouf said. “We didn’t do anything wrong. My children were killed, and the rest are in intensive care.”

Their father Zeyad Abu Maarouf told Reuters that the family had arrived in the “safe zone” a month ago after Israel told them to go to al-Mawasi.

When asked about the incident, the IDF told the BBC it could not provide a specific response without more information, but said it “follows international law and takes feasible precautions to mitigate civilian harm”.

Also on Sunday, a 20-year-old IDF soldier, Sergeant Yisrael Natan Rosenfeld, was killed in northern Gaza.

The increased Israeli military action comes as mediators begin new efforts to end the war and release the remaining hostages held by Hamas.

On Thursday, a senior Hamas official told the BBC mediators have intensified their efforts to broker a new ceasefire and hostage release deal in Gaza, but that negotiations with Israel remain stalled.

Qatari mediators have said they hope US pressure could help to achieve a deal, following a truce between Israel and Iran that ended the 12-day conflict between the countries.

On Sunday, Netanyahu told members of Israel’s domestic intelligence agency Shin Bet that “victory” over Iran opened up many possibilities, “first and foremost, to rescue the hostages”.

“Of course, we will also need to resolve the issue of Gaza, to defeat Hamas, but I believe we will achieve both missions. Beyond that, broad regional opportunities are opening up, in most of which – almost all – you are partners,” he said.

Trump previously said he was hopeful a ceasefire in Gaza could be agreed in the next week.

In March, a two-month ceasefire collapsed when Israel launched fresh strikes on Gaza. It said it wanted to put pressure on Hamas to release its hostages.

Israel also imposed a total blockade on humanitarian aid deliveries to Gaza at the start of March, which it partially eased after 11 weeks following pressure from US allies and warnings from global experts that half a million people were facing starvation.

That partial easing included the creation of a US and Israeli-backed aid group, the Gaza Humanitarian Foundation (GHF), after Israel accused Hamas of stealing aid. Hamas has denied this.

GHF’s aid system has been condemned by UN agencies. There have been repeated incidents of killings and injuries of Palestinians seeking aid.

Juliette Touma, communications director for the UN agency for Palestinian refugees, Unrwa, told the BBC that the new mechanism was “a killing field”. She said the distribution of aid in an orderly way could only be done through the UN and other humanitarian organisations.

GHF boss Johnnie Moore previously told the BBC World Service’s Newshour he did not deny deaths near aid sites, but said “100% of those casualties are being attributed to close proximity to GHF” and that was “not true”.

The previous ceasefire deal between Israel and Hamas – which started on 19 January – was set up to have three stages, but did not make it past the first stage.

Stage two included establishing a permanent ceasefire, the return of remaining living hostages in Gaza in exchange for Palestinians imprisoned in Israel, and the complete withdrawal of Israeli forces from Gaza.

Trump has called for ongoing corruption charges against Netanyahu to be dropped, describing proceedings as a “political witch hunt” delaying ceasefire negotiations.

On Sunday, an Israeli court accepted a request by the Israeli prime minister to delay his scheduled testimony for a week, due to diplomatic and security issues.

Netanyahu was charged in 2019 with bribery, fraud and breach of trust, all of which he denies.

Earlier in the week, Israeli opposition leader Yair Lapid said Trump should not “intervene in a legal process of an independent state”.

Israel launched its military campaign in Gaza in response to Hamas’s 7 October 2023 attack, in which about 1,200 people were killed and 251 others were taken hostage.

Since then, 56,500 people have been killed in Gaza, according to the territory’s Hamas-run health ministry.

Republican Senator Thom Tillis announces he will not seek reelection in 2026 following his opposition to Trump’s bill.

0

 Republican Sen. Thom Tillis of North Carolina said Sunday he will not seek reelection next year, an abrupt announcement that came one day after he staked out his opposition to President Donald Trump’s tax breaks and spending cuts package because of its reductions to health care programs.

His decision creates a political opportunity for Democrats seeking to bolster their numbers in the 2026 midterm elections, creating a wide-open Senate race in a state that has long been a contested battleground. It could also make Tillis a wild card in a party where few lawmakers are willing to risk Trump’s wrath by opposing his agenda or actions. Trump had already been threatening him with a primary challenge.

“In Washington over the last few years, it’s become increasingly evident that leaders who are willing to embrace bipartisanship, compromise, and demonstrate independent thinking are becoming an endangered species,” Tillis said in a lengthy statement.

Tillis, who would have been up for a third term, said he was proud of his career in public service but acknowledged the difficult political environment for those who buck their party and go it alone.

“I look forward to having the pure freedom to call the balls and strikes as I see fit and representing the great people of North Carolina to the best of my ability,” Tillis said in a statement.

Republicans hold a 53-47 edge in the Senate.

Trump, in social posts, had berated Tillis for being one of two Republican senators who voted on Saturday night against advancing the massive tax bill.

The Republican president accused Tillis of seeking publicity with his “no” vote and threatened to campaign against him, accusing the senator of doing nothing to help his constituents after last year’s devastating floods in western North Carolina from Hurricane Helene.

“Tillis is a talker and complainer, NOT A DOER,” Trump wrote.

The North Carolina Republican Party chairman, Jason Simmons, said the party wishes Tillis well and “will hold this seat for Republicans in 2026.” Sen. Tim Scott of South Carolina, the chairman of the campaign arm for Senate Republicans, did not mention Tillis in a statement but said the party’s winning streak in North Carolina will continue. Scott noted that Trump won the state three times.

Democrats expressed confidence about their prospects.

Former Rep. Wiley Nickel, who announced his candidacy in April, said he was ready for any Republican challenger.

“I’ve flipped a tough seat before and we’re going to do it again,” Nickel said in a statement.

Some said Tillis’ decision is another sign of the dramatic transformation of the Republican Party under Trump, with few lawmakers critical of the president or his agenda remaining in office.

It “proves there is no space within the Republican Party to dissent over taking health care away from 11.8 million people,” said Lauren French, spokesperson for the Senate Majority PAC, a political committee aligned with the chamber’s Democratic members.

Tillis rose to prominence in North Carolina when, as a second-term state House member, he quit his IBM consultant job and led the GOP’s recruitment and fundraising efforts in the chamber for the 2010 elections. Republicans won majorities in the House and Senate for the first time in 140 years.

Tillis was later elected as state House speaker and helped enact conservative policies on taxes, gun rights, regulations and abortion while serving in the role for four years. He also helped push a state constitutional referendum to ban gay marriage, which was approved by voters in 2012 but was ultimately struck down by the courts as unconstitutional.

In 2014, Tillis helped flip control of the U.S. Senate to the GOP after narrowly defeating Democratic Sen. Kay Hagan. During his more than a decade in office, he championed issues such as mental health and substance abuse recovery, Medicaid expansion and support for veterans.

As a more moderate Republican, Tillis became known for his willingness to work across the aisle on some issues. That got him into trouble with his party at times, most notably in 2023 when North Carolina Republicans voted to censure him over several matters, including his challenges to certain immigration policies and his gun policy record.

“Sometimes those bipartisan initiatives got me into trouble with my own party,” Tillis said, “but I wouldn’t have changed a single one.”

Donald Trump continues to emphasize Iran nuclear points amidst growing uncertainty | Latest updates on Donald Trump

0

US president denies multiple reports and accounts that say US strikes did not destroy Iran’s nuclear capabilities.

United States President Donald Trump has reiterated a vow not to allow Iran to get nuclear weapons following the end of Iran and Israel’s recent 12-day conflict, in which the US militarily intervened, and has stuck closely to his narrative as questions remain about the impact of US strikes on Iran’s nuclear sites.

On the Fox News programme Sunday Morning Futures with Maria Bartiromo, Trump repeated his claim that Iran was “weeks away” from making the weapons before Israel attacked on June 13. Nine days later, the US targeted Iran’s top three nuclear facilities: Fordow, Natanz and Isfahan.

Both US intelligence and the United Nations nuclear watchdog have ascertained that Tehran was not building a nuclear arsenal. Iran has long insisted that its nuclear programme is for civilian purposes only.

While Trump has said that the sites were “obliterated” by the US bombers, in the wake of the attacks, several major news organisations, citing intelligence sources, have reported that the US strikes did not destroy the facilities.

The International Atomic Energy Agency (IAEA) said on Monday that it was unclear what damage had been sustained at the Fordow plant, which houses the bulk of Iran’s most highly enriched uranium needed to make a nuclear weapon.

On Sunday, IAEA chief Rafael Grossi said Iran could restart uranium enrichment in a matter of months, while Trump insisted over the weekend that the attacks had set Iran’s nuclear ambitions back “by decades”.

According to an IAEA report last month, Iran has more than 400kg (880lb) of uranium enriched to up to 60 per cent purity, close to the roughly 90 per cent weapons grade – which is enough, if enriched further, for nine nuclear weapons.

Trump told Fox News that the news outlets questioning the efficacy of the attacks he ordered and lauded were spreading “fake news”.

“It’s just horrible and I could see it happening, and they [news outlets] tried to build that into a story, but then it turned out, no, it was obliterated like nobody has ever seen before and that meant the end to their nuclear ambitions at least for a period of time,” Trump said.

On whether or not Iran would restart its nuclear programme following the end of the conflict, Trump said, “The last thing they want to do right now is think about nuclear.”

During the attack on the sites, reports emerged that Iran had removed the enriched uranium from Fordow, but Trump claimed that was false.

“It’s a very hard thing to do, plus we didn’t give them much notice because they didn’t know we were coming until just then and nobody thought we would go after that site because everybody said that site was impenetrable… it’s at the bottom of a mountain and it’s granite,” he said.

“[But] the bomb went through it like butter, like it was absolute butter,” he said.

Trade talks

Separately, Trump told Fox that US trade talks with Canada would be stopped “until such time as they drop certain taxes” after Canada pushed ahead with a new digital services tax on foreign and domestic technology companies.

Regarding a trade deal with China, Trump said that while Washington, DC has a large trade deficit with Beijing, the US was currently “getting along” with China.

The president added that he had found a buyer for the social media platform TikTok, by a group of “very wealthy people”, who he will reveal in about two weeks after he extended a ban on the app for the third time, for another 90 days.

Economists warn that Trump’s fiscal policy and criticism of the Federal Reserve could jeopardize the US safe haven status

Donald Trump’s “breathtaking fiscal policy excess” and attacks on the Federal Reserve’s independence risk diminishing the US’s status as the ultimate safe haven for foreign investors, economists polled by the Financial Times have warned.

The poll, conducted by the Kent A Clark Center for Global Markets at the University of Chicago Booth School of Business, found that more than 90 per cent of economists surveyed were either somewhat concerned or very concerned about the safe-haven role of US dollar denominated assets over the next five to 10 years.

The White House insisted this week that Trump’s economic policies will help cut US debt as it made a final pitch to win over fiscal hawks in the Senate and get the president’s flagship tax bill over the line.

But independent estimates, including by fiscal watchdog the Congressional Budget Office, indicate the measures contained in the budget bill — which Trump has dubbed “the big beautiful bill” — will push the US federal debt past its previous post-second world war high later this decade.

While the dollar usually appreciates during bouts of global market panic, the sharp sell-off in global equity markets following Trump’s unveiling of aggressive reciprocal tariffs on April 2 was coupled with a depreciation of the US currency.

The benchmark S&P 500 has since recovered and is at an all-time high amid hopes that Trump’s economic policies will not derail growth or fuel inflation in the world’s largest economy.

“The safe-haven assets appear to be [the] Swiss Franc and gold. In fact, [the] US looks like an emerging market, whereby policy uncertainty leads to rising risk premia that drive long-term yields up and the currency value down,” said Saroj Bhattarai at the University of Texas at Austin.

The dollar is trading at a three-year low amid concerns over fiscal sustainability and question marks over the Federal Reserve’s independence, as Trump continues to attack chair Jay Powell over his reluctance to cut interest rates amid concerns that the global trade war could push up inflation.

“Breathtaking fiscal policy excess is all but guaranteed, and that invites, though hardly guarantees, a change of heart about dollar assets,” said Robert Barbera at Johns Hopkins University.

“Marry that emerging reality to a de facto White House takeover of the Fed — through a Powell firing or the championing of a hack as a Powell replacement? That would move me from somewhat concerned to very, very concerned.”

Powell’s term ends in May 2026 and speculation is rife that Trump could name his pick to replace him early in a bid to undermine the Fed chair.

“Fiscal deficits, deliberate government actions to shrink the US financial account and devalue the dollar, uncertainty about succession at the Fed and questions about Fed independence all negatively affect [the safe haven status of the dollar],” said Anna Cieslak at Duke University.

US Treasury yields, which usually fall in times of market volatility, rose in early April. While the benchmark 10-year yield has since fallen to about 4.3 per cent, many economists polled believe it could soon hit 5 per cent — a level that would spark concern within the Trump administration.

Almost three-quarters of the survey’s 47 respondents tipped the yield on 10-year debt to rise above 5 per cent by the middle of next year.

“US Treasury [bonds] might not be a safe asset any more,” said Evi Pappa at Universidad Carlos III de Madrid. “Look at what happened at ‘liberation day’ to the US 10 year versus European yields.”

Economists have become more gloomy on the US economic outlook since they were last polled in March.

The median expectation is now for the world’s largest economy to expand by 1.5 per cent over the course of this year, slightly down from an estimate of 1.6 per cent in the spring.

Separate surveys of economists and US households and businesses show that forecasts for growth and confidence sank rapidly after the April 2 tariffs were announced, but have since partially recovered on the back of the trade truce between the US and China and rises in equity prices.

Economists have also become more hawkish on price pressures, with the median expectations for core PCE inflation this year moving up from 2.8 per cent in March to 3 per cent in June, amid expectations that Trump’s tariffs would be passed on to US consumers.

But only a few respondents believed there was a more than 50 per cent chance of core PCE inflation exceeding 4 per cent and the unemployment rate simultaneously exceeding 5 per cent at any point between now and the end of 2026.

A better than expected reading for consumer price index inflation in May boosted hopes that less of the cost of tariffs than feared would be passed on to American shoppers.

But the annual figure for core personal consumption expenditures inflation in May, published on Friday, rose slightly to 2.7 per cent, from 2.6 per cent the previous month.

Marchand makes a strong comeback with a dominating triple win at Indy Summer Cup Day 4

2025 INDY SUMMER CUP

A significant portion of the swimmers on the US World Championship roster, along with several other big names, are racing this week in Indianapolis, treating swim fans to some relatively fast swimming as we approach this summer’s major international meets. That included Leon Marchand tonight, after the French swimmer DFS’ed the 200 fly and 400 free yesterday, but took on the 100 free, 20 back and 200 IM tonight.

Simone Manuel took a dominant victory in the women’s 100 freestyle on Day 4, winning the event by nearly a second to continue her great form this season. At U.S. Nationals she posted her fastest time since 2019 to take third and come within five-hundredths of an individual swim. Manuel was out tonight in 25.73, and despite Regan Smith closing the gap slightly on the second 50 touched first in 53.28, less than half a second off her season-best 52.83.

Smith knocked over a second off her previous best to go 54.15, showing some serious sprint speed in an off-event for her. She did not race the 100 free at U.S. nationals, but has certainly thrown her hat in the ring for future forays in the event.

She tripled up on Day 4, swimming the 200 back and the 200 IM in this finals session as well as the 100 free. She was up in the 200 back just 20 minutes later, where she took the win in 2:06.84. She had set a new meet record of 2:09.77 in the morning, and was significantly faster again in the final to swim exactly a second slower than she was at U.S. Nationals.

Miranda Grana, who will swim the 100 and 200 back for Mexico in Singapore next month, took third in 2:14.83, three seconds off her best from Mexican Nationals this year.

Smith placed first in the 200 IM as well to round off her session, posting a time of 2:10.35 to win by nearly seven seconds and shatter the meet record by more than four. She was out sub-1:00 in 59.49, and then split 40.44 on breaststroke and 30.42 in freestyle to set her season-best in the event.

In the Men’s 100 free, Chris Guiliano followed on from his meet record of 47.79 from the heats this morning to shave another seven-hundredths, going 47.72 in the final. He was out fast in 22.56, joined under 23 seconds by Matt King (22.91), and stormed home in 25.16 to take the win. King came back in 25.40 to go 48.31, faster than he was in either heats (48.39) or finals (48.41) at U.S. Nationals.

Several World Championship swimmers tried this event on for size tonight, including Luke Hobson (49.64), Hubert Kos (49.42) and Leon Marchand (49.70). Marchand had scratched his events yesterday, but returned to racing with a big schedule tonight. Carson Foster (49.87) and Rex Maurer (49.98) were in tonight’s ‘B’ final, which was won by their compatriot and WUG’s entrant Baylor Nelson in 49.83.

Ruslan Gaziev, who is coming off an 18-month whereabouts suspension, took third in the ‘A’ final in 48.94. He won the event at Canadian Trials this year in 48.37, and holds a best time of 48.27 from 2023. In total, 15 swimmers broke the previous meet record of 50.67 over the course of the day.

Marchand, Kos, Baylor Nelson and Carson Foster completed the same triple as Regan Smith, in what looked to be a punishing Texas schedule for tonight.  A stacked 200 backstroke final saw five World Championship competitors race – Carson Foster, Rex Maurer, Kai van Westering, Hubert Kos and Leon Marchand – with World and Olympic Champion Hubert Kos taking the win in a new meet record of 1:56.74. Marchand pushed him close the whole race to finish in 1:57.14, which looks to be a new best time for him, with no one else breaking two minutes.

The 200 IM saw the competitors split up, with Foster and Shaine Casas in the ‘B’ final and Kos and Marchand in the ‘A’. Casas took the win ahead of Foster 1:59.71 to 2:00.07, as Foster matched his 200 backstroke time to the hundredth. Marchand and Kos were nearly even at halfway in their final, but Marchand blew Kos away with a 33.90/28.52 back half to roar to a 1:57.23 that shaves 0.04 off his season best and maintains his #8 ranking in the World this season.

Utilizing Redox Flow Batteries for Sustainable Energy and Desalination

0

Two of the greatest challenges humanity faces in an era of climate emergency and transition to renewable energies are obtaining drinking water and energy storage. One of the most common and efficient solutions for the first challenge is reverse osmosis desalination, and for the second, batteries. However, in laboratories, scientists and engineers are already exploring new technologies that could combine both solutions to advance the energy transition. We’re talking about desalinating redox flow batteries or Redox Flow Desalination (RFD) technology, a field in which New York University has recently made considerable advances. In this article, you will learn about:

What are redox flow batteries?

Before explaining what a desalinating redox flow battery is, it’s important to understand the general concept of redox batteries. This technology works by storing energy in liquid solutions called electrolytes, which contain chemical compounds capable of changing from an oxidized state to a reduced state and vice versa.

During operation, two different types of electrolytes are pumped from separate tanks through a central electrochemical cell. In this cell, the electrolytes interact through an ion-exchange membrane that allows the passage of ions but separates the two liquids. The chemical reaction that occurs in this cell generates electricity, which can be used or stored as needed.

These batteries have a long lifespan, as they can withstand many charge and discharge cycles without significant degradation. They are particularly useful for storing renewable energy, such as solar or wind power, as they can store excess energy generated and release it when production is low.

The new generation of desalinating redox batterie

Redox Flow Desalination (RFD) is an innovative technique that combines water desalination and energy storage into a single system. In this case, it operates by circulating salt solutions and redox agents through electrochemical cells. Ion-exchange membranes separate these solutions, allowing the selective transfer of ions, resulting in the extraction of salt from seawater and the production of fresh water.

The RFD process not only produces drinking water but also allows for the storage of excess energy from renewable sources. During desalination, the system can store energy in the redox molecules and then release it when needed, acting as a battery. This energy storage and release capability is crucial for balancing the fluctuation in renewable energy demand and water needs.

Advances at New York University

Both redox flow batteries and desalination systems based on this technology are far from widespread implementation. The former suffers from certain disadvantages, such as the need for large storage tanks due to their low energy density, while the latter are still in the experimental phase. However, New York University has managed to improve redox flow desalination through a new approach that increases desalination efficiency by 20%.

The RFD system they developed uses a structure of four channels separated by ion-exchange membranes (IEM). Research highlights that increasing the flow rate in the electrolyte channels reduces resistance at the electrolyte-membrane interface. This significantly improves salt removal and the system’s energy efficiency. For example, increasing the flow rate from 5 to 50 mL/min boosts the salt removal rate by 16.7 times while reducing energy consumption.

Currently, the most common technology for storing renewable energy is lithium batteries, but who knows if redox flow batteries are destined to play a significant role in the decarbonization of the economy and, in parallel, help alleviate drinking water needs.

Massive demonstration demands resignation of Thai PM Paetongtarn Shinawatra

Thousands of protesters have gathered in the Thai capital Bangkok, calling for the resignation of Prime Minister Paetongtarn Shinawatra after a phone call she had with the former Cambodian leader Hun Sen was leaked.

In the call, which was about a recent incident on their border, she addressed Hun Sen as “uncle” and said a Thai military commander handling the dispute “just wanted to look cool and said things that are not useful”.

The call has sparked public anger. Paetongtarn apologised, but defended the call as a “negotiation technique”.

Before leaving to visit flood-hit northern Thailand, Paetongtarn told reporters it is the people’s “right to protest, as long as it’s peaceful”.

Saturday’s rally was the largest of its kind since the ruling Pheu Thai party came to power in 2023.

Thousands braved the monsoon rain and blocked the roads at the Victory Monument war memorial in Bangkok, waving Thai flags and holding placards with slogans such as “PM is enemy of state”.

Protest leader Parnthep Pourpongpan said the prime minister “should step aside because she is the problem”.

Seri Sawangmue, 70, travelled overnight by bus from the country’s north to join the protest.

He told AFP news agency that he was there “to protect Thailand’s sovereignty and to say the PM is unfit”.

“I’ve lived through many political crises and I know where this is going,” he added.

Paetongtarn has said she will no longer hold future calls with the former Cambodian leader, but Parnthep told Reuters that many Thai people felt she and her influential father were being manipulated by Hun Sen.

Paetongtarn, 38, is the daughter of Thaksin Shinawatra, the deposed former prime minister who returned to Thailand last August after 15 years in exile. She has only been in office for 10 months and is the country’s second female prime minister, with the first being her aunt Yingluck Shinawatra.

Protesters are calling for the end of Shinawatra leadership.

The rally was organised by a coalition that has protested against Shinawatra-led governments for more than two decades.

The group said in a statement read to crowds that the executive branch and parliament were not working “in the interest of democracy and constitutional monarchy”, Reuters reported.

As well as the flags and placards, people carried umbrellas to protect themselves from the rain. When it stopped, a rainbow formed over Victory Monument.

On Tuesday the Constitutional Court will decide whether to take up a petition by senators seeking Paetongtarn’s removal for alleged unprofessionalism over the Hun Sen call.

Hun Sen said he had shared the audio clip with 80 politicians and one of them leaked it. He later shared the entire 17-minute recording on his Facebook page.

The call was about a recent dispute between Cambodia and Thailand, which saw tensions increase in late May after a Cambodian soldier was killed in a border clash, plunging ties to their lowest in more than a decade.

But the tension between the two nations dates back more than a century, when the borders were drawn after the French occupation of Cambodia.

Both have imposed border restrictions on each other, while Cambodia has banned Thai imports from food to electricity, as well as Thai television and cinema dramas.

Despite the tensions between their countries, the Shinawatras’ friendship with the Hun family goes back decades, and Hun Sen and Paetongtarn’s father consider each other “godbrothers”.
