Thailand's army chief, General Prayuth Chan-ocha, has declared himself as acting prime minister until someone can be found to serve the post full time.
Prayuth will act as acting prime minister for administrative purposes, Bangkok Post on Friday quoted as saying an announcement by the National Peace and Order Maintaining Council set up following Thursday's military coup.
The announcement was made late Thursday night, reported Xinhua.
Later, the military summoned ousted Prime Minister Yingluck Shinawatra and 22 associates including powerful relatives and ministers in her government, to a meeting at an army facility at 10am on Friday.
Yingluck is the sister of Thaksin Shinawatra, a billionaire telecommunications tycoon turned prime minister who won huge support among the poor but the loathing of the royalist establishment, largely over accusations of corruption and nepotism.
Yingluck was forced to step down as prime minister by a court two weeks ago, but her caretaker government, buffeted by six months of protests, remained nominally in power, even after the army declared martial law on Tuesday.
The meeting with Yingluck could set the tone for Prayuth's rule as he tries to steer the country out of crisis and fend off international criticism of the latest lurch into military rule.
