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.

Paetongtarn Shinawatra, Thailand’s youngest prime minister and scion to the country’s most prominent political dynasty, may lose power barely a year after taking the top political office.
