The SDLP leader Mark Durkan has called for all sides in the Good Friday Agreement to commit to a firm implementation timetable.
At his party's annual conference in Armagh, Mr Durkan called for London, Dublin and all the parties in the North to sit down and produce an implementation pact for the entire agreement.
Mr Durkan also called on paramilitary organisations top disband and said the two governments must stop pandering to the gunmen.
Meanwhile, speaking before a party meeting in Dublin, the Sinn Fein chairman Mitchel McLaughlin said the British government made a serious mistake in suspending the political institutions in the North.
Mr McLaughlin called on the British government to demonstrate how they intend to implement the Good Friday Agreement.
He expressed concern that the British government was moving towards the unionist demand for a renegotiation of the agreement.
