My Lords, when I started life in politics a long time ago—50 years or so ago—when the general public, or people who had political ideas, thought about the security services they were generally criticised because they were spying on people who should not be spied on, such as political activists and all the rest of it. By the time the noble Baroness, Lady Manningham-Buller, and myself worked together with the intelligence and security agencies, the criticism that would come was whether the intelligence services had not done enough to protect us. That is the way in which things have changed over the last 40 or 50 years, so we have to be very careful how we balance this idea of accountability on the one hand and inevitable secrecy on the other. How do we do it?
There are reports by the Investigatory Powers Commissioner and the intercept commissioners. When I had to intercept, I was overseen by a commissioner
every year. I had a meeting with him—a former judge—on whether I did this or that right, and on whether this or that was important. I come back to the point I have made in the last two days of Committee about the Intelligence and Security Committee itself. That is the vehicle by which Parliament holds the security services accountable. My noble friend Lord Coaker has been making that distinction all the time: the services being accountable to Government for what they do is very different from being available to Parliament.
Of course, details of who has been tapped and details of intelligence operations cannot come here, to this House or the other House—of course not. However, they can go through the committee which both Houses have set up, which meets in private, is non-partisan, and which has Members of both Houses who have great experience on it, to deal with these issues. That is why I appeal to the Minister—we had the debate on the issue on Tuesday—to think again about using the ISC to answer some of the issues that my noble friend Lord Coaker quite rightly raised.
