Roger Helmer shouldn't have stood as a Conservative.

This is what Roger Helmer, a Conservative MEP, said back in June:

I personally regard our commitment not to accept the Lisbon Treaty as the heart of the Manifesto on which I was elected two weeks ago, and I should regard any retreat from it as a betrayal of our supporters, and of the British people. This is not the way to restore trust in politics. I am confident that the Party will indeed do what it says it will do — if I were not, I should not have stood as a Conservative. If however I am wrong, and at some future stage it becomes clear that it would not, that the Conservative Party intended to resile from the referendum promise, then I for one should have to consider my position very carefully.

Will be interesting to see if Helmer finally realises he has no place in Cameron's Conservatives.
