Thailand's Constitutional Court on Tuesday suspended Prime Minister Paetongtarn Shinawatra from duty pending a case seeking her dismissal, in a major setback for a government under fire on multiple fronts and fighting for its survival.

Paetongtarn Shinawatra is accused of ethical lapses in a conversation with the Cambodian leader Hun Sen and has faced calls to resign.

Thailand’s embattled prime minister was suspended from duty Tuesday and could face dismissal pending an ethics probe over a leaked phone call she had with Cambodia’s powerful former leader.
