DUP leader Ian Paisley has said he does not believe the IRA are capable of becoming democrats.
Ian Paisley has rejected the statement from Gerry Adams
He dismissed a statement from Sinn Fein President Gerry Adams that the IRA was talking about whether it should pursue its goals exclusively through politics.
It followed his previous call for the IRA to "fully embrace" democracy.
However, Mr Paisley said "a leopard doesn't change its spots" and that the "democracy train was leaving the station without Sinn Fein".
On Tuesday, Mr Adams said: "I am confident that the IRA will take this debate forward with all the seriousness that it deserves.
"I firmly believe that the way forward is by building political support for republican and democratic objectives across Ireland and internationally."
Following Mr Adams' call to the IRA, the terror group said it was giving "due consideration" to his appeal.
Republicans have been under pressure since the £26.5m Northern Bank raid in December and the killing of Robert McCartney in January.
Talks last year failed to restore devolution, which stalled amid claims of IRA intelligence gathering at Stormont in 2002.
