The head of Thailand's military government says he will not step down if an August referendum fails to approve a draft constitution it is promoting.

Prime Minister Prayuth Chan-ocha was responding Monday to a reporter's question of whether he would emulate Britain's David Cameron, who announced he would resign after UK voters in June 23's Brexit referendum rejected his position endorsing staying in the European Union.

Leaders of Thailand's Pheu Thai party, whose government was deposed by a military coup led by Prayuth in May 2014, had suggested he resign if the draft constitution did not pass.

Prayuth said he had no intention of leaving, because Britain did not have the same problems as Thailand and, unlike Cameron, he did not come to office by election.
