I am grateful for the comments and questions from the hon. Members for Greenwich and Woolwich and for Brent North. As they anticipated —I may be becoming too conventional—I will resist the amendment. Again, this is about where primary legislation stops and secondary legislation begins, and the Opposition are right to test us on that. It is perfectly legitimate for people to take different views on where that starts and stops, and we know that our colleagues in the other place caution us, where we can be cautioned, not to take too many Henry VIII powers. We are undertaking a self-denying ordinance to not take an additional Henry VIII power today, on the basis that this is of sufficient magnitude, albeit recognising the challenges that have been outlined, that it should be in the Bill and be clear, and that any appropriate changes should come through similar processes. For that reason, although I understand the rationale for it, and I am always happy to listen to the underlying points, the Government will not support the amendment.
