European Union (Referendum) Bill

I am sorry that the leader of the hon. Gentleman’s party was not able to flip a few lentil burgers last night to entice more of his colleagues to take part in this important debate. Will he just clarify his position? In the highly unlikely event that we have a Liberal Democrat Government after the next election, and this Bill, as is most likely, has been passed in this Parliament, would they abolish the undertakings that this Bill would give to tie us to a referendum, and thus give the British people a say at last?
