The pro-election activists, led by the Democracy Restoration Group, had announced plans to assemble at Thammasat University at 5pm on Monday and remain there overnight, before marching to Government House on Tuesday morning. They plan to deliver an ultimatum to the prime minister, General Prayut Chan-o-cha, to hold a general election this year, instead of next February as promised by the premier. Reports said academics, political activists and local-rights activists in some provinces had been called by security agencies to ask whether they would join the demonstration. The NCPO has already tried to stop the red shirts and political activists from going to the assembly, the dean posted on his Facebook page. Indeed, it has visited political activists in order to pressure them not to go to Bangkok, he added.
