Thailand¡¯s Constitutional Court dismissed Prime Minister Paetongtarn Shinawatra from office on Friday for an ethics violation after only a year in power, in another crushing blow to the Shinawatra political dynasty that could usher in a new period of turmoil.

Paetongtarn, who was Thailand¡¯s youngest prime minister, becomes the sixth premier from or backed by the billionaire Shinawatra family to be removed by the military or judiciary in a tumultuous two-decade battle for power between the country¡¯s warring elites.

In its verdict, the court said Paetongtarn violated ethics in a leaked June telephone call, during which she appeared to kowtow to Cambodia¡¯s former leader Hun Sen when both countries were at the brink of an armed border conflict. Fighting erupted weeks later and lasted five days.
