I see two possible means of escape.
1. UKIP gain enough seats to bring about, in concert with those Conservatives who agree with them, an imminent and straightforward in-out referendum in which, hopefully, a majority of voters will opt for the UK to leave.
2. By one means or another, the EU will collapse due to the wishes of Eurosceptics throughout Western Europe (needless to say, East Europeans would far prefer to remain in the EU).
Certainly, I am of the firm opinion that the longer we remain subject to rule from Brussels, the worse it will be for our nation. Interesting times ahead, if nothing else.
