Are you seriously suggesting that we go back to Europe, and say “I’m sorry we made a mistake “?
We’d be stripped like a corpse on a battlefield. The first thing to go would be the rebate , and then a number of historical “ scores” would be settled with Gallic gusto . The EU would punish us with barely disguised relish “ pour encourager les autres”
If you think the country’s polarised now, you’d have a de-facto civil war on your hands.
