I thank my hon. Friend for his constructive comments. I genuinely understand the concerns about speed expressed by him and other Members. That point was considered extensively by the National Security Council, and in the end we made a balanced judgment. We believe that by having 2027 as the target, by the end of this Parliament we will have put in law an irreversible process for removal. The risk of going faster relates to the integrity of the network and the challenges in that respect. I would rather we got to a point where we had got it out completely by 2027, and I think that is a realistic timetable for doing so.
