Again, the clause is primarily a consequence of the Rottman case, and we are trying to clarify the position. It is firmly rooted in PACE, in replicating powers that are contained in sections 17 and 19 of that Act, and I am sure that Members will accept that it will sometimes be impossible to obtain a warrant before entering premises to arrest someone who is wanted for extradition, if that person is trying to run away, for example. That is why we have included the clause.

I hope that I can reassure the hon. Gentleman by saying that, with the codes of practice and the inclusion of the affirmative resolution procedure, there will be plenty of opportunities for Parliament to satisfy itself about the detail. As I said, the clause is about clarifying the position, as requested and supported by the police.
