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.

Paetongtarn has faced growing dissatisfaction over her handling of the latest border dispute with Cambodia, involving an armed confrontation on May 28 in which one Cambodian soldier was killed.

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