Im unaware of the legalities involved, how much of a say to the EU have? Do they have to simply accept our decision or vote on it etc?
Ive always maintained (and given how they have leveraged their position so far) that they would likely want us "all in" if we decided to back out.
No Veto, into the €URO, the lot. Quite frankly, why wouldnt they?
Force us into full and committed participation, instead of the arms length attitude we have always maintained.
That information comes from the guy who wrote Article 50, I'd imagine he would know as well as anybody what is and isn't possible. We may yet find out.
