The National Anti-Corruption Commission (NACC) has reportedly agreed to launch an investigation into the ethical conduct of Prime Minister Paetongtarn Shinawatra, following the leak of a phone call between her and Cambodian Senate President Hun Sen.
The move comes in response to a petition filed last Friday by Senate Speaker Mongkol Surasajja, who submitted formal requests to both the Constitutional Court and the NACC.
The petitions seek the removal of Prime Minister Paetongtarn from office, citing concerns raised by the leaked conversation.
The official complaint questions whether the prime minister engaged in corruption by intentionally violating the constitution or other laws, or if she committed a serious breach of ethical standards expected of a public official.
Simultaneously, a separate petition was submitted to the Constitutional Court, asking it to rule on whether Paetongtarn’s premiership should be terminated under Sections 160 and 170 of the constitution, which pertain to ministerial ethics and the grounds for removal from office.
The leaked conversation reportedly included derogatory remarks about the commander of the 2nd Army Region, whom Paetongtarn allegedly labelled as an “adversary.”
The call also featured what was interpreted as a deferential tone toward Hun Sen, with the prime minister expressing a willingness to comply with his requests — an exchange that critics say undermines Thai national interests.
According to reports, the NACC has instructed relevant officials to transcribe the audio, translate any Khmer-language portions, interview witnesses, and study legal precedents, including the ethical case involving former prime minister Srettha Thavisin.
If sufficient grounds are found, the commission is expected to propose the formation of a special committee to formally investigate Paetongtarn’s conduct.
Meanwhile, the Office of the Constitutional Court announced that the court’s next session to review pending cases is scheduled for July 1.
