Fixed-term Parliaments Bill

I have three points for clarification. Is the Minister guaranteeing that there will be no clash of election days between, say, Scotland and Westminster? Will he guarantee that the six months he has spoken about will be put into legislation? Finally, who will have the power to shift the dates? We feel that that should be for the devolved legislatures. Also, the point made by the hon. Member for Foyle (Mark Durkan) about the difficulties of getting a two-thirds majority was apposite. But it is all in the mix.
