A Thai court is set to decide whether suspended Prime Minister Paetongtarn Shinawatra should be permanently removed from office following a leaked phone call with former Cambodian leader Hun Sen, BBC reported.

In the recording, Paetongtarn was heard criticizing Thailand’s army and seeking to ease tensions over a border dispute, remarks that embarrassed her party and sparked a backlash. She later apologized, saying her comments were part of a “negotiating tactic,” but senators demanded her resignation and petitioned the court.

The verdict, due Friday, will be a major test for the Shinawatra family, Thailand’s most influential political dynasty. If removed, Paetongtarn would become the fifth prime minister dismissed by the court since 2008, adding fresh uncertainty to Thai politics, according to BBC.
