The Irish and British governments must spell out how they are going to honour commitments under the Belfast Agreement to advance the peace process, Gerry Adams said last night.
The Sinn Fein president told a party election rally in Armagh the future direction of the IRA was not the only issue that needed to be addressed.
"I made it very clear in my speech last week that there are many problems to be resolved in the time ahead, particularly for those parties with a responsibility to implement the Good Friday Agreement. "It especially has huge implications for the two governments.
"They face significant challenges - not least implementing commitments they have made and not honoured." Efforts to revive the Stormont Assembly have been stuck in a rut ever since Sinn Fein and the Reverend Ian Paisley's Democratic Unionists failed to strike a deal last December.
Talks involving both parties and the Irish and British governments stumbled when the IRA rejected DUP calls for photographic evidence of the completion of weapons decommissioning. Since then the political climate has soured after the £26.5 million sterling Northern Bank robbery and the murder of Belfast father-of-two Robert McCartney which has been blamed on the IRA.
The Democratic Unionists claim both incidents proved Sinn Fein unfit for government, and in recent days there have been indications that the party will rule out power sharing with republicans under the mandatory coalition system which operated at Stormont.
Last week Mr Adams called on the IRA to begin an internal debate and claimed there was a democratic alternative to the Provisionals' campaign of violence which they must cease. The West Belfast MP said he was making the proposal to the IRA in a bid to drive the peace process forward to stop the rot.
However, political opponents have responded with scepticism to his call and to the IRA's confirmation that it is holding an internal debate. The Sinn Fein president said at tonight's rally marking the launch of Newry and Armagh assembly member Conor Murphy's Westminster campaign: "Demilitarisation, policing, humans rights and equality are all crucial matters that are primarily the responsibility of the government.
"What do they plan to do about these? "Power sharing is a central tenet of the Good Friday Agreement. Will the governments deliver on this obligation or will they acquiesce again to Unionism?
"These are key matters, key areas of responsibility for London and Dublin. My initiative means that there can be no possible excuse for the process to remain in stagnation."
