European Union Bill

I confess that I am having some difficulty following the noble Lord’s argument on this point and I wonder whether he can help me. As my noble friend Lord Lamont has said, the EU already has exclusive competence in the area of international agreements. It has competence over the single market. It has competence over regulation. It can legislate in these areas using the normal provisions of the EU—that is what the competence gives it; that is under the existing treaty—so we are not talking about stopping it legislating. I am trying to understand what it is the noble Lord thinks might require treaty change to enable the EU to do something; and why, if it requires treaty change, that will not in any case take several years to accomplish, in the way that treaty changes normally do. I fail to understand what is the restriction to act in areas where the EU already has competence.
