European Union (Referendum) Bill

May I take my hon. Friend back to the point he made about the Members of the other place having the right to vote? That raises the concern that several of us have had from the outset about the wisdom of addressing such a constitutionally far-reaching measure in a private Member’s Bill. In particular, has he sought any advice on the implications of the Bill’s consideration in the other place? Will Members there have to declare an interest or say how they intend to vote in such a referendum? Will they have to disbar themselves from taking part in the debate? As far as I can see, this is new constitutional territory.
