On the face of it, the NICC is a total failure as it does not achieve its aims of agreement between the two sides or of introducing ‘rolling devolution’ (gradual introduction of devolution as and when the parties involved see fit to accept it). Nevertheless, coming as it does not long after the Conservative-sponsored Sunningdale Agreement, the NICC indicates that no British government will be prepared to re-introduce majority rule in Northern Ireland. During the debates William Craig accepts the possibility of power-sharing with the SDLP, a move that splits the UUUC and precipitates the eventual collapse of the Vanguard Unionist Progressive Party (VUPP).
