BANGKOK — Thailand's Constitutional Court will on Wednesday (Aug 14) decide the fate of Prime Minister Srettha Thavisin, in a ruling that could see him dismissed after less than a year in office and plunge the country into deeper political uncertainty.

Srettha, a real estate tycoon with no background in politics, is the subject of a complaint from ex-senators appointed by the former military government, who say he violated the constitution when he gave a cabinet post to a former lawyer who was once jailed.

If Srettha is removed, the 500-seat parliament must convene to choose a new premier, with the prospect of more upheaval in a country dogged for two decades by coups and court rulings that have brought down multiple governments and political parties.

The same court last week dissolved the anti-establishment Move Forward Party, the hugely popular opposition, ruling its campaign to reform a law against insulting the crown risked undermining the constitutional monarchy. It regrouped on Friday under a new party.

Srettha's Pheu Thai Party and its predecessors have borne the brunt of Thailand's turmoil, with two of its governments removed by coups in a long-running grudge match between the party's founders, the billionaire Shinawatra family, and its rivals in the conservative establishment and royalist military.

Srettha denies wrongdoing in appointing to cabinet former Shinawatra lawyer Pichit Chuenban, who was briefly imprisoned for contempt of court in 2008 over an alleged attempt to bribe court staff, which was never proven.

"We've done our best and have submitted closing statements. I've set up plans based on the people's needs and the care-taking PM can consider them," Srettha said on the eve of the verdict, which will be delivered at 3 pm (0800 GMT)

Test of truce

The decision comes at a tricky time for Thailand's economy, which Srettha has struggled to jumpstart. The government has estimated growth of just 2.7 per cent for 2024, lagging regional peers, while Thailand has been Asia's worst-performing market this year with its main stock index down about 17 per cent year-to-date.

The case could be a test also of a fragile truce between political heavyweight Thaksin Shinawatra and his enemies among the conservative elite and military old guard, which enabled the tycoon's return from 15 years of self-exile in 2023 and ally Srettha to become premier the same day.

Deputy premier Phumtham Wechayachai would take over as caretaker if Srettha falls. According to some political experts, it is likely Pheu Thai would still have the clout to lead the next administration, after a period of uncertainty over who will be in charge.

"The government will still have 314 seats — the coalition remains united," said Olarn Thinbangtieo, deputy dean of Burapha University's Faculty of Political Science and Law.

"There may be some impact on confidence, but that would be in the short term."

The next premier would need to have been nominated a prime ministerial candidate by their parties prior to the 2023 election, with Thaksin's 37-year-old daughter Paetongtarn Shinawatra among Pheu Thai's options.

If successful, she would be the third Shinawatra premier after Thaksin and her aunt, Yingluck Shinawatra.

Other potential candidates include Interior Minister Anutin Charnvirakul, Energy Minister Pirapan Salirathavibhaga and Prawit Wongsuwan an influential former army chief who was involved in the last two coups.
