Piphob told a local radio station the two factors that will decide the future of the PAD demonstrations were: whether ousted premier Thaksin Shinawatra is tried for alleged corruption, and whether the Samak Sundaravej government will go ahead with the Constitution amendment.
He said they would watch if any attempt was made to amend Article 309, which grants immunity to the military junta and recognises their actions and appointments.
Confusion arose after another PAD leader, media mogul Sondhi Limthongkul, set six conditions for calling off the protest, which included solving the high oil price and rising cost of living.
Piphob said it was Sondhi's personal opinion and supporters of the PAD should only abide by PAD-sanctioned statements. Yesterday also saw the ruling People Power Party airing support for Samak's softer stance towards the PAD after fears of a violent crackdown following the premier's hard-line stance earlier.
PPP spokesman Kudeb Saikrachang said the premier should not pay too much attention to the PAD as its value is inflated.
Opposition leader Abhisit Vejjajiva warned Samak not to act arrogantly and said the premier should heed the growing public resentment at the government's attempt to interfere with the media and amend the charter to help certain politicians.
"I want the government to learn from the past. Why don't they review it and learn that the interests of some people shouldn't be placed above that of everybody else," said Abhisit.
Meanwhile, a group of some 200 protesters wearing white arrived at the Democrat Party headquarters yesterday calling for the party to stop seeking extra-constitutional ways to overthrow the government. The group, claiming to be from the Klong Toey area, said Democrat MP Somkiat Pongpaiboon should not be allowed to play a role as a PAD leader.
