Ulster Unionist leader David Trimble has claimed Sinn Fein's leadership appears to be in denial about the root problems in the Northern Ireland peace process.
Following talks with the Northern Ireland Secretary Paul Murphy at Stormont, Mr Trimble accused Sinn Fein leader Gerry Adams of "living in cloud-cuckoo-land" over the problems in the process.
"I think it is important that we do bear in mind exactly what caused and triggered the present problem and that was the activities of the republican movement," said Mr Trimble.
Sinn Fein President Gerry Adams said on Thursday night insisted that the main problem in the peace process was the failure of the British government to honour its commitments under the Good
Friday Agreement and he criticised the suspension of power-sharing.
Mr Trimble today countered: "The onus remains and rests essentially with the republican movement to repair the damage that has been done."
