"Mr Abhisit has never asked for talks with Thaksin as his legal adviser Noppadon Pattama claimed," Mr Chavanond said.
On Saturday, Mr Chavanond told reporters Thaksin would be welcome to sit via video-conference at a possible meeting between Mr Abhisit and Ms Yingluck.
He said people had asked him whether a meeting between Thaksin and Mr Abhisit would be possible. Thaksin can make Skype calls to his sister, caretaker Prime Minister Yingluck Shinawatra, the spokesman said.
Previously, Thaksin's legal adviser told reporters that his boss was ready to hold talks with Mr Abhisit but they must abide by the rule of law. He said Thaksin would do anything for the interest of the country, not for those who talked and acted differently.
On "Man of State" chairman Saiyud Kerdphol's comment that Privy Council president Prem Tinsulanonda agrees with his group's idea of seeking His Majesty the King's discretion in pulling the country out of the political crisis, Mr Noppadon said he was not aware that Gen Prem had responded to Gen Saiyud's proposal.
"Gen Prem is the Privy Council president and is a revered senior figure of the country. He would act in line with the constitution and the Man of State's proposal has no legal basis.
"The best and most direct solution to the country's problem is to hold a general election. Gen Saiyud should call on the Election Commission to quickly hold it and urge the Democrat Party to contest it," the lawyer said.
Pheu Thai Party leader Charupong Ruangsuwan, Democrat secretary-general Juti Krairiksh and Democraty chief legal expert Wirat Kalayasiri declined to comment of the Man of State's proposal.
