I thank the Minister for her very full reply. I asked whether the approach of my noble friend Lord Anderson of Ipswich in 2016 to
the scrutiny of the Investigatory Powers Act, as it went through both Houses, might not be a model to follow. In our meeting last week, the Minister discussed with myself and those of us who are sceptical about the use of child CHIS for evidence the requirement for this. To convince us, she was kind enough to indicate that the 17 cases that we know of through IPCO produced a result that was deemed, in the balance of all things, positive and justified the use of those cases. In the absence of that sort of evidence, those of us whose primary concern is the best interests of the child are understandably very cautious and a little sceptical. We are willing to be convinced but we need the evidence to be convinced, please.
