European Union (Referendum) Bill

I am grateful to the right hon. Gentleman and I praise him for the candour of his approach to this debate. We all agree that reform is needed, but the British public need to be sure that sufficient reform is going to take place if we are to stay within the EU. Does he agree that having a referendum after the renegotiation has happened will absolutely crystallise in the minds of the rest of the EU member states the fact that we are absolutely serious that the current position is just unsustainable?
