I reiterate the commitment that the Prime Minister has already made that there will be a referendum by the end of 2017 if there is a Conservative Government. There is virtually no movement in polling evidence in the demand for a referendum. I will say something else to my hon. Friend: by creating the referendum we have—I will use the phrase again—lit a fire under our partners in Europe. They now know that they have to deliver change that is substantive and meaningful; not some backroom political deal, but something that will satisfy the British people in a referendum. That is what is driving the debate.
