Investigatory Powers Bill

Very much so. That shows the time sensitivity of many investigations, and I am grateful to my hon. Friend for bringing it up. We know from evidence sessions in both Committees that 100% of counter-terrorism cases and 90% of serious organised crime cases involve communications data evidence. We are talking about very serious cases indeed. My concern about new clause 1 is that it in no way removes the risk that high-level criminals and terror suspects will be told that they have been investigated by law enforcement and the security services. Such people are more likely to be the subject of warrants because of their criminality, so we would be handing the investigations to those criminals on a plate.
