Thailand's cabinet appointed Deputy Prime Minister Phumtham Wechayachai to serve as acting prime minister on Saturday, following a Constitutional Court ruling that terminated Paetongtarn Shinawatra's premiership. 

Minister to the Prime Minister's Office Chusak Sirinil announced the appointment following a special cabinet meeting, which also appointed Prommin Lertsuridej as PM's Secretary General. 

Chusak said that the cabinet approved a strict framework for its operations during this transitional period to ensure stability without exceeding its mandate. 

The move was a constitutional requirement following the court's ruling, that the existing cabinet continues to govern in a caretaker capacity until a new administration takes office. 

The Secretariat of the House of Representatives has issued a notice to members of the parliament to convene from September 3 to 5. 

The lower house of the parliament is set to vote for the new prime minister based on the list of candidates submitted before the May 2023 general election.
