The government of Thai Prime Minister Paetongtarn Shinawatra was hanging by a thread on Thursday following the withdrawal of a major coalition partner, building pressure on her to resign after just 10 months in power.

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.

The move by the Bhumjaithai party followed the leak of a recorded phone call between PM Paetongtarn and Cambodia’s former leader Hun Sen.
