European Union Referendum Bill

Given that the EU has fundamentally changed since the early 1970s when we joined it, it is right that the Bill has been introduced. Whatever the result of the referendum, we can now all agree with that. Will the right hon. Gentleman address the issue of fundamental change in our relationship? Given that the majority of European capitals are moving closer and closer to political union, does he accept that the negotiations aiming to accommodate countries that do not wish to go down that road are terribly important? What guarantees will the Labour party be looking for when it comes to those negotiations?
