Thailand’s Constitutional Court has suspended Prime Minister Paetongtarn Shinawatra following a petition alleging she breached ethics in a call to Hun Sen, Cambodia’s strongman, which he leaked. Ms Paetongtarn appears to disparage a Thai general for being hot-headed over a border spat between the two countries. The petition, by senators, suggests conservative forces in the army, palace and parliament are calling time on the populist movement long led by Ms Paetongtarn’s father, Thaksin Shinawatra. He, too, is in court on charges of lèse-majesté. In 2008 the generals ousted him in a coup; in 2014 they seized power from his sister. This time the Shinawatras look likelier to be dispatched with a gavel. ■
