My Lords, the noble Lord, Lord Fox, is quite safe; I am not going to come and hit him, but I am going to try to demolish a few of his arguments.
I will start with the word “transparency”, which appears again in some of the amendments in the name of the noble Lord, Lord Coaker. The work of the security and intelligence agencies can never be transparent. It is in the interests of those agencies that as much as can safely be known of what is done in their name is known, which is why my organisation sought law in the 1980s. But there will always be things that cannot be made public because, if they are, we might as well pack up and go home.
Appealing as the amendments in the name of the noble Lord, Lord Fox, might be on the surface, for a start, telling people that they have been subject to interception would require us to alter earlier parts of the IPA because it would be illegal. To do so would also risk sources and methods. Of course, they would not be itemised, but let us consider a speculative case of a Member of the other House who has a relationship with a young Chinese lady. Let me emphasise strongly that this is not based on any knowledge of anything. Indeed, when I was director-general of MI5, we still operated the Wilson doctrine. Somebody in that MP’s office approaches my former colleagues and raises concerns with them. A warrant is obtained, signed by the Prime Minister, and subsequently it becomes clear that the concerns of the individual in the office—the source of the information—were absolutely justified. Now, we cannot tell that individual at any stage whether he or she is acquitted of any wrongdoing or ends up care of His Majesty’s jails. We cannot at any stage tell him because it risks sources and methods.
