Deputy Prime Minister Prawit Wongsuwon on Thursday brushed aside a call by a former yellow-shirt protest leader for a coup.
Prawit's comments followed the proposal by Sondhi Limthongkul, former co-leader of the defunct People's Alliance for Democracy.
The Deputy PM made only one remark -- "There won't be any coup" -- when asked about the matter. The government has repeatedly ruled out a coup in the past.
A Facebook page called "Sondhi Talk'' posted a clip of Mr Sondhi expressing his opinions on the political situation in a show on a satellite television channel "News One'' on Tuesday.
During the show, he said: "For me, a coup is not evil. If the constitution is to be amended, all involved must be allowed a say to make sure the charter is fair."
The opposition Move Forward Party (MFP), meanwhile, said on Thursday it would join a proposed reconciliation committee -- but only if Prime Minister Prayut Chan-o-cha resigned and monarchy reform was among the topics for discussion.
Growing tension has been felt on the streets of Bangkok, where anti-dictatorship protesters have held mass rallies calling for Gen Prayut's resignation, a rewrite of the entire constitution and monarchy reform.
Meanwhile, the anti-government protesters rallied again on Thursday at three locations in Bangkok.
The first was in front of the Hindu temple on Silom Road, a central business area, where they displayed political artwork.
The second was on the Sky Walk at the Pathumwan junction, arranged by a group of Chulalongkorn University students to mark the 13-day anniversary of the government's crackdown on student protests on Oct 16.
The final one was in front of the office buildings of the Nation Multimedia Group on Bang Na-Trat Road.
