Pheu Thai leader Cholnan Srikaew said it will invoke a clause of the Constitution allowing an urgent debate on national issues, though it would not include a no-confidence vote.
Under Article 152 of the Constitution, a motion signed by at least 10 per cent of MPs can trigger a general debate to inquire about facts or recommend actions.
Cholnan said Pheu Thai will hold a meeting with smaller opposition parties on Tuesday (January 19) to discuss the debate, which is expected to be held on January 21.
Cholnan said Prime Minister Prayut Chan-o-cha’s coalition government was shaky because the ruling Palang Pracharath was not the largest party in terms of MPs. Pheu Thai won 136 seats at the 2019 election while Palang Pracharat won 116.
