I know that the noble Lord and many others in this House are concerned, and rightly so, to ensure that our security services and counterterrorism measures are adequate for the threat we face. If there was any suggestion that that was not the case, clearly, we would want to look at that and take the necessary steps. The Investigatory Powers Bill, which is about to receive pre-legislative scrutiny, is landmark legislation that futureproofs the existing legislation, which gives the powers the security services need at this time. So while the noble Lord makes some interesting points, what is important is that that Bill receives the proper scrutiny that Parliament expects it to receive. However, at the same time, I assure the noble Lord and the House that, if there is anything the security services do not have now that they need to do their work, we will review that legislation and reconsider our approach to it.
