rolling devolution model possible?

Another Liam Clarke article, again in the Sunday Times, reports that Peter Hain has accepted that the government could adopt a rolling devolution model – in which the Assembly is restored, but the power-sharing executive is delayed. There are some quotes about the possibilities from the DUPs Peter Robinson and the SDLP’s Mark Durkan, who reiterated his position on the BBC’s Politics Show – arguing that the interim proposal would only be an option “if parties aren’t willing to form an inclusive executive”. Which already seems to be the case. Undoubtedly the two main unionist parties would be happy with the interim proposal, although when, or if, the second step is to be taken would be of concern to the other parties.
