He did it purely for votes, as his last term he promised the same thing and it didn't happen, he's used it entirely to regain votes. His own party is now very against him and the public is now even more against him, the fact he shelved the fox hunting repeal means he's losing the countryside votes.
P much he's doing whatever he wants now.
I am personally Pro-EU, granted I want massive overhauls of what our agreement is etc, but leaving it will generally be a bad idea as we have zero friends outside the EU anymore. We basically ditched the commonwealth out of demand by the EU, we need to repair our relations with the countries that actually made us who we are todai, (the commonwealth) and renegotiate our EU terms, because we could easily run the EU and make it good unlike fucking germany and their retarded ways.
I am sort of thinking Cameron wants out of the EU and is using this leaflet as a push, as if we left the EU, no UK citizen has access to EU legal services, and we will entirely rely on his government for everything, p much granting him a sort of marshal law. Probably conspiracy, but it all seems to be aiming at he's very clever at his plans or he is just a fucking moron. (most likely the latter)
