Daniel Hannan (MEP, UK) does not need many words for a convincing case:
We have locked ourselves into a declining regional bloc, with whom we run a massive deficit, at the expense of the developing and Commonwealth markets with whom we are still in surplus (I quote the trade figures in the piece). We have disadvantaged our farmers, betrayed our fishermen and burdened our small entrepreneurs. We now propose to wreck our financial services sector. On top of all this, we have ceased to be an independent democracy. Oh, and we pay £19 billion a year for the privilege of having these things done to us.
