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.

The judges voted unanimously Tuesday to take the petition accusing her of a breach of ethics, and voted 7 to 2 to suspend her from duty.
