Thai Prime Minister Paetongtarn Shinawatra's coalition government is on the brink of collapse after a leaked phone call between her and Cambodia's strongman ex-leader Hun Sen.
They were discussing a border dispute that has ramped up tensions between the two neighbours in recent weeks after a Cambodian soldier was killed in a clash in May.
Paetongtarn appeared to dismiss a Thai military commander in the 17-minute call shared by Hun Sen on Facebook on Wednesday. She said the officer "just wanted to look cool and said things that are not useful".
She defended the call as a "negotiation technique" but opposition figures are calling for her to resign, saying she has undermined the Thai army.
Bhumjaithai, the second-largest party in her ruling coalition, quit the alliance on Wednesday after the leaked phone call, dealing a major blow to her Pheu Thai party's position in parliament.
