My Lords, I had not intended to say anything on this part of the Bill, not least because all these lawyers at various levels of leading counsel, pupil-master and so on do so much better than me. It seems to me that it is wrong in principle for members of the security and intelligence services to have immunity from the law.
I think that the noble Lord, Lord Purvis—the Minister may deal with this in his summing up—has confused the authorisations that are approved for CHIS activity involving criminality with what this part of the Bill seeks to do. I hope that in his reply the Minister will acknowledge the wide concern within the Committee, including from people such as me who have spent a career in the Security Service, and will consider an amendment to address some of these problems.
I quite comprehend that it is not necessarily easy to explain what the problem is that we are trying to address without revealing secrets but, again, I endorse the view that it would be helpful to hear what the ISC has thought on these matters. We heard from the noble Lord, Lord West of Spithead, at an earlier stage, that he and the ISC recognised that there was a problem that needed addressing. For my part, I am unable to support this as a solution.
