Thailand's embattled Prime Minister Paetongtarn Shinawatra was facing the prospect of losing her government's majority on Friday as a vital coalition partner looked set to demand her resignation after just 10 months in power.

During the conversation, Paetongtarn called for a peaceful resolution of the border dispute and disparaged an outspoken Thai army general who she said "just wants to look cool", a red line in a country where the military has a high profile and significant political clout.

Thailand’s government faces potential collapse after Prime Minister Paetongtarn Shinawatra’s leaked phone call unleashed fresh political turmoil, with the leader now facing calls to resign as she grapples with the exit of the second-biggest party in her coalition.
