Thailand Set to Elect New Prime Minister

Locations Affected: Thailand

Thailand’s lower house of parliament is scheduled to hold a special session on 05 September to elect a new Prime Minister. The session follows the dismissal of former Prime Minister Paetongtarn Shinawatra by the Constitutional Court for reported ethical violations. Under the Constitution, the new Prime Minister must be selected from candidates nominated during the 2023 general election.

Reason for the Special Session

On 30 August 2025, the Constitutional Court dismissed Prime Minister Paetongtarn Shinawatra over private conversations deemed a breach of ethics. Acting Prime Minister Phumtham Wechayachai and cabinet members have continued in caretaker roles since the dismissal. On 04 September, the Pheu Thai Party submitted a royal decree to dissolve parliament, but the Privy Council rejected it on legal grounds, citing limitations on the powers of a caretaker government. The Pheu Thai Party subsequently announced Chaikasem Nitisiri as its candidate for Prime Minister and pledged to call snap elections if successful.

Implications of the Parliamentary Vote

  • The Bhumjaithai Party, led by Anutin Charnvirakul, has secured support from the opposition People’s Party, which holds the largest number of seats in parliament. In return, Bhumjaithai has agreed to dissolve parliament within four months of forming a government.
  • The Pheu Thai Party’s nomination of Chaikasem Nitisiri introduces a competing bid, which may create divisions among coalition partners and test existing political agreements.
  • A new government will likely delay ongoing legislative and financial reforms initiated under the previous administration until new leadership priorities are established.
  • The possibility of early elections within four months remains high if the Bhumjaithai–People’s Party agreement holds.

Outlook on the Situation

Thailand is entering a period of political transition. The parliamentary vote on 05 September is expected to result in the election of a new Prime Minister, with Anutin Charnvirakul currently viewed as the frontrunner due to cross-party support. Should he secure office, a snap election is anticipated by early 2026. In the interim, political uncertainty may affect decision-making processes, delay policy implementation, and influence business operations, particularly in sectors reliant on government contracts and regulatory stability.

Organizations are advised to remain situationally aware and prepare appropriate contingency plans.
