Volkswacht Bodensee - Thai PM faces growing calls to quit in Cambodia phone row

The coalition government led by Shinawatra's Pheu Thai party is on the brink of collapse, throwing the kingdom into a fresh round of political instability as it seeks to boost its spluttering economy and avoid US President Donald Trump's swingeing trade tariffs.

The conservative Bhumjaithai party, Pheu Thai's biggest partner, pulled out on Wednesday saying Paetongtarn's conduct in the leaked call had wounded the country and the army's dignity.

Losing Bhumjaithai's 69 MPs leaves Paetongtarn with barely enough votes to scrape a majority in parliament, and a snap election looks a clear possibility -- barely two years after the last one in May 2023.

Two coalition parties, the United Thai Nation and Democrat Party, will hold urgent meetings to discuss the situation later on Thursday.

Losing either would likely mean the end of Paetongtarn's government and either an election or a bid by other parties to stitch together a new coalition.

- Resignation calls -

The Palang Pracharath party, which led the government up to 2023 and is headed by General Prawit Wongsuwan -- who supported a coup against Paetongtarn's aunt Yingluck -- called for the premier to resign.

The party's statement said the leaked recording showed Paetongtarn was weak and inexperienced, and incapable of managing the country's security.

"This already has proved that Thailand has a leader who will lead the country to a bad situation and weakness," the statement said.

Another opposition party, Thai Sang Thai, also called for Paethongtarn to step down, saying her conversation with Hun Sen had damaged the kingdom's sovereignty and the army.

In the leaked phone call, Paetongtarn is heard discussing an ongoing border dispute with Hun Sen -- who stepped down as Cambodian prime minister in 2023 after four decades but still wields considerable influence.

She addresses the veteran leader as "uncle" and refers to the Thai army commander in the country's northeast as her opponent, a remark that sparked fierce criticism on social media, particularly on Pheu Thai page and Royal Thai Army page.

Thailand's armed forces have a long played a powerful role in the kingdom's politics, and politicians are usually careful not to antagonise them.

The kingdom has had a dozen coups since the end of absolute monarchy in 1932, and the current crisis has inevitably triggered rumours that another may be in the offing.

If she is ousted she would be the third member of her family, after her aunt Yingluck and father Thaksin Shinawatra, to be kicked out of office by the army.

- Awkward coalition -

Paetongtarn, 38, came to power in August 2024 at the head of an uneasy coalition between Pheu Thai and a group of conservative, pro-military parties whose members have spent much of the last 20 years battling against her father.

Growing tensions within the coalition erupted into open warfare in the past week as Pheu Thai tried to take the interior minister job away from Bhumjaithai leader Anutin Charnvirakul.

The loss of Bhumjaithai leaves Pheu Thai's coalition with just a handful more votes than the 248 needed for a majority.

The battle between the conservative pro-royal establishment and Thaksin's political movement has dominated Thai politics for more than 20 years.

Former Manchester City owner Thaksin, 75, still enjoys huge support from the rural base whose lives he transformed with populist policies in the early 2000s.

But he is despised by Thailand's powerful elites, who saw his rule as corrupt, authoritarian and socially destabilising.

Thaksin returned to Thailand in 2023 as Pheu Thai took power after 15 years in self-exile overseas.

The current Pheu Thai-led government has already lost one prime minister, former businessman Srettha Thavisin, who was kicked out by a court order last year, bringing Paetongtarn to office.
