The UK is a democracy, something Cameron is making perfectly clear is here to stay.
Europe or should I say the EU, is a corrupt dictatorial state that, as proven by its refusal to allow referendum on any subject, regardless of what it is.
Greece for example felt the need to ask its people if the Government should accept the EU's demands it take on a massive IMF loan with 25% interest, only to be informed they couldn't. The only referendum they could hold was one of in or out.
Ireland's referendum was rejected as it came back with the wrong answer, Cameron was ignored and his demands weren't even negotiated and the UK is sold as the bad boy in the pack.
It beats me why all you pro EU cowards just don't pack your bags and go live there, ah, it's a pity because you only speak English!
