Well, my view has always been that any deal should be ratified by the Parliaments—plural—of the UK. If that doesn't happen, the matter would either have to be settled through an election or indeed, possibly, by a referendum on the deal itself. Because, if there's no other way of resolving it, then the people who voted in 2016 have a perfect right to decide what kind of deal they want to approve from 2018 onwards. It seems right that that should happen. But it seems to me that the first port of call is for the Parliaments of the UK to examine any deal and decide whether that deal should be supported or not. If there is then, for example, a general election if that deal is rejected, and that produces an inconclusive result, well, how else can it be resolved other than by a referendum on the deal? I think that becomes inevitable at that stage.
