If there is to be a second referendum on membership of the EU, as I hope there will be, then prepare for controversy galore. The original question on the ballot paper – This or Not This – may have been vague, but it was simple and the campaigning straightforward. I can think of a number of significant and unavoidable differences next time round that will rustle a few feathers. The most obvious complication being caused by a potential third choice on the menu – May’s eventual deal with the EU, when and if that ever comes. Remain, Leave Hard or Leave Deal.
