The Democrat Party is insisting on escalating its protest on Ratchadamnoen Avenue until the blanket amnesty bill is completely revoked.
Democrat MP Suthep Thaugsuban, who is leading the Ratchadamnoen rally, said the protest would continue despite signs the premier is taking a softer line, as his party did not trust the government.
He was responding to Prime Minister Yingluck Shinawatra's remarks that the government and its MPs would accept the decision of the Senate on the bill.
"We will not be fooled anymore," Mr Suthep told protesters last night.
He accused Ms Yingluck of lying to the people in insisting she was never involved in the bill. She also accused protesters of exploiting the amnesty issue as a political tool for their own benefit. "That's pitiful. She knows very well what she did," he said.
Mr Suthep said Ms Yingluck should admit that she pressed ahead with the bill under her own steam.
"Don't you hand us this victory in bits," he said.
"The protest will continue until we achieve ultimate victory, which is that the bill is scrapped, " he added.
Democrat leader Abhisit Vejjajiva said the government still intends to push ahead with an amnesty bill as Pheu Thai members have always said that if parliament failed to pass the blanket amnesty bill, then other similar bills would be drafted.
"We can't trust them. We will ultimately stop them issuing such an evil law," he said.
Nitithorn Lamlua, adviser to the Network of Students and People for Reform of Thailand, said some demonstrators of the network and the Dharma Army have moved to Phan Fa Bridge on Ratchadamnoen Avenue. They are preparing the venue for other demonstrators who will follow them to the bridge tomorrow. About 500 members of the Dharma Army reached Phan Fa from Uruphong intersection yesterday.
Network coordinator Uthai Yodmanee said it would move protesters at 10am today and they would reach government offices. They could go to Government House if they attract a large enough crowd, he said.
