I recognise that my right hon. and learned Friend is advancing that argument with the best possible intention, but we live in a time when, because of terrorism and the fear of terrorism in particular—to pre-empt my concluding remarks—there has been an encroachment on our fundamental principles of liberty and justice, which we see elsewhere in the Bill. It is in that context that we must make sure that the security services are held properly to account in a transparent and credible way.
Here is the crucial point: in other Select Committees, transparency can do the heavy lifting, but as has been mentioned, transparency is not available in relation to the ISC. Precisely because of that, we need an elected Chair. I appreciate that the Prime Minister might find himself in a position where he had to reject a candidate in advance of their election, but that is surely a better option than going forward with a Committee whose independence from prime ministerial patronage can be questioned. I appreciate that the Prime Minister might have to engage in some politics on this issue, but that is after all his job.
