Thai Prime Minister Prayuth Chan-ocha said Tuesday that elections will be held in November 2017 after a junta-backed constitution was approved in a referendum on the weekend.
Prayuth dismissed statements made by the head of the constitutional drafting committee Meechai Ruchuphan that elections would be pushed back to 2018.
"The people have passed the referendum and according to our roadmap elections will be held in November 2017," Prayut told reporters. "Why would it be postponed to 2018?"
A new constitution was a major part of the military government's "roadmap to democracy" after it took power in a coup in May 2014.
A majority of Thais voted for the junta-back charter on the weekend, with over 60 per cent approving the document. Campaigning for or against the charter had been banned by the military.
Critics say the constitution gives too much power to the military who will appoint the entire upper house of parliament and have a veto on constitutional amendments.
