I am really sorry that the hon. and learned Lady—particularly with her legal expertise—is giving credence to such nonsense. The facts are that our participation in European arrangements on the sharing of information between police forces and judicial systems rests on instruments based in the treaties and grounded in European law. Under article 50, on the day that we depart the EU, the treaties, and therefore all instruments flowing from the treaties, cease to apply to the United Kingdom. That is why we say that we are ambitious for an agreement—a new, deep and special partnership with our EU neighbours—that encompasses security co-operation as well as trade. I wish that she would support that.
