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.

Thailand's Constitutional Court suspended Prime Minister Paetongtarn Shinawatra on Tuesday, pending an ethics investigation over accusations that she was too deferential to a senior Cambodian leader when the two discussed a recent border dispute in a phone call that was leaked.
