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

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.

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.
