My Lords, I thank the Minister for her typically courteous and thoughtful response, particularly her offer to talk to a number of my noble friends and other noble Lords about possible oversight that would be acceptable to the Government. Could she look again at Amendment 15? I and my noble
friend Lord Blunkett worked very closely with the Security Service, in my case when I was Secretary of State for Northern Ireland—including with the noble Baroness, Lady Manningham-Buller—GCHQ, and, when I was in the Foreign Office, with MI6. I have authorised warrants, as I have explained, for vital work in surveillance and interception, and worked with undercover officers.
I appeal to the noble Baroness to meet my noble friend Lord Blunkett and myself informally to discuss the terms of Amendment 15, because it is very practical. It can happen in real time; I have been involved in authorising warrants in real time, including one on Islamist bombers planning to attack London when the operation was live. So, it does deal with her point. It is practical; in some respects, it is the most practical of all these oversight measures. It would give greater legitimacy to and authority for the deployment of undercover officers for the purposes that she is quite properly seeking. They can play vital roles in combating terrorism, for example. I ask her to look again at this and perhaps meet us to discuss it.
