The British government was urged tonight to look at alternative ways to rule Northern Ireland.
With six days to go before the Assembly Election, the Reverend Ian Paisley's Democratic Unionists claimed the Belfast Agreement was incapable of delivering stable government.
The party set out three alternative models to the power sharing executive which operated at Stormont during devolution.
But they were accused by nationalist SDLP leader Mr Mark Durkan of only being interested in "majority rule".
The DUP proposed:
A voluntary coalition of two or more parties at Stormont as opposed to the "forced coalition" of Ulster Unionists, DUP, Sinn Féin and the SDLP which operated under devolution.
A system which ensured power resided with the Assembly rather than ministers, removing the need for any cabinet.
A government with an effective exclusion mechanism which would enable the institutions to continue if a party misbehaved.
The DUP said voters believed the Agreement had failed and had delivered a "bloated bureaucracy".
The party refused to say which model of government it preferred.
East Derry MP Mr Gregory Campbell said: "In negotiations we will not make the basic errors of the Ulster Unionist Party who published their bottom line in advance of negotiations and then broke it.
"Our proposals will be designed to create lasting devolution and be capable of being supported by unionists and nationalists alike.
"Up until this election we had the artificial glass ceiling which said it is the Agreement, the whole Agreement and nothing but the Agreement. Today with the publication of this we are going through that glass ceiling."
