Interesting, though much I knew.
It appears like it's been a slow process of building up a United States of Europe. The United Kingdom must always retain our sovereignty. Though, with a better deal with Europe, we are probably safe from handing over further powers to the EU. Without sureties and upon a referendum it's almost certain that we will exit the Union.
I feel people really want to leave anyway and even if we do get a better deal, I do feel an exit from Europe is on the cards.
So we must prepare for this real possibility.
