Thailand’s Constitutional Court has suspended Prime Minister Paetongtarn Shinawatra from office pending an investigation over a leaked phone call with a former Cambodian leader.

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

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.
