Deputy prime minister Prawit Wongsuwan is serving as acting prime minister of Southeast Asia’s second-biggest economy.

“I will continue to do my duty and responsibility as defence minister for the people and Thailand every day,” Prayuth said on his official Twitter account late on Thursday.

The Constitutional Court on Wednesday decided to hear a petition brought by the main opposition party arguing that Prayuth’s years spent as the chief of a military junta after he took power in a 2014 coup, should count toward his overall time in office. The constitution stipulates a term limit of eight years for the prime minister.

It remains unclear when the court will deliver a decision on the review.

The controversy over Prayuth’s term limit is the latest episode in nearly two decades of intermittent political turmoil, including two coups and violent protests, stemming from opposition to military involvement in politics and demands for greater representation as political awareness grows.

A government spokesperson, Anucha Burapachaisri, said today the cabinet continues to function as normal.
