A touch mischievous.
Sorry Martin, it seemed in keeping with the thread.
I just wish that he had said that there would need to be a majority of the electorate in favour of Brexit to trigger the exit process.
Indeed, for a vote with such long-term consequences, a simple majority vote is normally insufficient. This is not about electing someone who can be removed in 4-5 years or less, this is an irreversible change which should require it to be generally seen that most people really want to take the step. In such cases, it is common practice to require a 'supermajority', for example, over 50%
of the electorate, or alternatively over 2/3 of those who voted, with a minimum turnout. If change is genuinely 'generally seen', it should be easy to get a supermajority.
Anyway, all that is now academic. We are where we are, and the question is not if, but how. Cameron's mistake was his confidence that he could put this away, once and for all, by setting the bar low and winning a simple majority vote. As one of Cameron's fellow dinner guests famously said to his face, "not even my golf club alters its rules by a simple majority vote".
