The Rev Ian Paisley's Democratic Unionist Party said it will not participate in any review of the Belfast Agreement.
Emerging from talks at Stormont with the Northern Ireland Secretary Mr Paul Murphy, Dr Paisley claimed the Government appeared to be focused on a review to save the Agreement.
"Our position will be that we are not taking part in any review. The Government will still talk to us. He [Mr Murphy] has made it clear that his door will still be open."
Mr Paisley, who was joined at the meeting by the party's MPs Mr Peter Robinson, Mrs Iris Robinson, Mr Nigel Dodds and Mr Gregory Campbell, noted Mr Murphy had not ruled out Stormont elections next May.
However he believed the Government was loath to allow the election to go ahead as scheduled. "He [Mr Murphy] doesn't want any elections. He wants to have an agreement with the present constitutional position of the parties," the DUP leader said
"He made it clear that an election would bring up a lot of changes. He admitted in a partial way that the Democratic Unionist Party did represent a majority of unionists".
Mr Paisley confirmed that the party had raised the position of prison officers whose personal details were discovered in the hands of republicans at the time when an alleged spy ring at the heart of the Northern Ireland Office was uncovered last month.
