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 Tuesday suspended Prime Minister Paetongtarn Shinawatra as it adjudicates an ethics complaint triggered by a leaked phone conversation between her and influential senior Cambodian lawmaker Hun Sen about a smoldering border dispute that had left a Cambodian soldier dead.

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.
