Thailand’s embattled prime minister was suspended from duty Tuesday and could face dismissal pending an ethics probe over a leaked phone call she had with Cambodia’s powerful former leader.

She is the third member of her family to hold the prime minister’s office — and the third to face the possibility of removal before her term ended.

Thailand’s Constitutional Court suspended Prime Minister Paetongtarn Shinawatra from office until it rules on a petition seeking her permanent removal over alleged ethical misconduct, deepening a crisis that threatens to end her family’s over two-decade dominance of the country’s politics.
