I know that we have agreed to support certain EU policies throughout the time we have been members, but equally for over 45 years, British governments of all political hues have stopped EU policies where they have thought they weren't good for Britain.
In the 19 years of existence of the Euro, for instance, we have never been forced to join and, I think you would agree, that if we stayed in the EU it still wouldn't be forced upon us. And I would suggest that a lot of the things you are mentioning (single bank, single currency, single army) will go exactly the same way.
One of the biggest issues for me is that we are throwing away 45 years of hard negotiated benefits to Britain. (Before UKIP MEP's started getting elected and deciding not to turn up !)
*edit*
And stating that
Is just factually wrong. Do you really think the British Government would accept all of these things with no vetoes or opt-outs ? (Because EU history would suggest the complete opposite).
I guess at some point we'll find out what it's like to have control back.
I hope for everybody's sake people like Westdene are correct, sadly he's done nothing to convince me that's even remotely possible.
