Critics of everything, such as myself, have a duty from time to time to say what they think should happen and not merely to denounce everyone else’s plans as nonsense.

It is in this spirit that I offer today a complete and utter solution to the Brexit crisis.

I should start by saying that I think Brexit is a very bad idea that should be revoked. I do not, however, think that this is likely to happen. If it does, nothing that follows has relevance.

And so to the way ahead.

There are just four possible approaches, none of them perfect.
