The main opposition Pheu Thai Party will nominate Chaikasem Nitisiri for prime minister should the Constitutional Court rule at the end of the month that Gen Prayut Chan-o-cha's time as premier has already ended.
Mr Chaikasem, the Pheu Thai's chief strategist, is the party's only remaining choice to compete for the premiership in parliament, according to Pheu Thai leader Dr Cholnan Srikaew.
