Investigatory Powers (Amendment) Bill [HL]

Lord Carlile of Berriew Excerpts

Report stage
Tuesday 23rd January 2024 Lords Chamber

[Lord Anderson of Ipswich (CB)]

My Lords, it is a pleasure to follow such a strong and powerful speech, and to agree with so much of it. I will speak to Amendment 40, which is based on my report of last year and repeats an amendment that I tabled in Committee and that was introduced there by the noble and learned Lord, Lord Hope of Craighead, my co-signatory then as now. The amendment has two objectives. The first is to ensure that the third part of the triple lock is not too easily wrested away from the Prime Minister.

We are often told that someone is unavailable when they are travelling, are in a meeting, have stepped out of the office or have simply asked not to be disturbed for the afternoon. Indeed, the noble Baroness, Lady Manningham-Buller, used the word in the first of today’s debates on the Bill, albeit in a different context, to describe the status of a Minister, as she put it, during the night or over the weekend. Nobody suggests that reasons such as these should be sufficient for the third lock of the triple lock to be handed to someone else. Unavailable is simply the wrong word. The public interest, in clear and accessible laws, requires us to use the right word. Using the wrong word and then glossing it by guidance or Statements from the Dispatch Box is not a good alternative. I suggest that the right word is “unable”, and I am delighted that the Intelligence and Security Committee and the noble Lord, Lord West, had the same thought in their Amendments 39 and 43.

The second objective of Amendment 40 is to allow provision to be made for the situation in which a Prime Minister is available to apply the third lock but might be considered, or consider himself, unable to do so by reason of conflict of interest. This could be the case if the communications in question were addressed to or from a Prime Minister’s sibling in Parliament. I see that the noble Lord, Lord Johnson of Marylebone, has just left his place. It could be the case if those communications were addressed to or from the Prime Minister himself or herself. Nobody doubts that the agencies currently have the power, and will continue to have the power after the Bill is passed, to request a Prime Minister’s communications to be intercepted. Nor is there any mystery about what will happen if such a request is ever made. It will be put to a Secretary of State for authorisation—presumably the Home Secretary or the Foreign Secretary, depending on the context. If that authorisation is granted, a judicial commissioner—presumably the most senior of them, the Investigatory Powers Commissioner—will be asked to approve it. So far, so uncontroversial.

The issue that arises is what should happen next. Under Clause 21, the request must be put before the Prime Minister unless it happens that he is ill or away from secure communications, in which case the third lock can be passed on to another Secretary of State and the Prime Minister’s communications can be intercepted without his knowledge. A precedent for the delegation of this most sensitive of powers already exists; indeed, it exists in the text of this Bill. But what if the Prime Minister is available? In such a case, the third lock must, under Clause 21, be left in the hands of the Prime Minister himself. He is statutorily barred from passing it on to anyone else, even if he—or, let us say, the Cabinet Secretary on his behalf—took the view that he is unable to take the decision for reasons of conflict of interest. That is notwithstanding the fact that conflict of interest, as the noble and learned Lord, Lord Hope, said in Committee,

“surely is a reason why a Prime Minister, although available, should not exercise the power”.—[Official Report, 13/12/23; col. 1902.]

That principle is so important that perhaps the undoubted practical difficulties to which the noble Lord, Lord West, referred need to take second place to it.

The triple lock was designed to ensure that the communications of parliamentarians could be intercepted only with the consent of the Prime Minister. It was not designed to give the Prime Minister himself an effective veto over the interception of his own communications. Immunities or quasi-immunities of that kind might have their place in some presidential systems, but they seem out of place in a parliamentary system in which the Prime Minister is primus inter pares. However, just such an immunity is perpetuated by Clause 21, and the amendments on this theme from the noble Lord, Lord West, which I otherwise support, do not remedy the situation.

Amendment 40 does not prescribe a detailed solution to this sensitive problem, but it leaves the door open to one. My concern in tabling it was to ensure that we do not legislate in such a way as to prevent a solution being found to the situation in which a conflict of interest arises in circumstances that would be vanishingly rare but that, if they ever did arise, could be of the highest importance to our national security.

I have reflected on what could be done without Amendment 40 if there were serious grounds to intercept a Prime Minister’s personal communications because one of his correspondents or the Prime Minister himself were under suspicion. Perhaps a possible answer would be to wait until the Prime Minister was out of reach of secure communications and then proceed with the interception if the approval of a judicial commissioner and two Secretaries of State could be secured. That is not a very principled or satisfactory answer to the issue of conflict of interest, but it is permitted by Clause 21 and might still be better than a prime ministerial veto. I should say that everything I have said about Clause 21 and interception applies also to equipment interference under Clause 22.

I hoped to generate a debate on this topic by tabling this amendment and, thanks to your Lordships’ indulgence, I have had a chance to do so. I would like to have invited the House of Commons to debate it too, but without the numbers to press this amendment to a vote there will be no such invitation, at least by this route. None the less, I am grateful to the ministerial team and to their shadows in your Lordships’ House and the Commons for discussing this issue with me in a degree of detail. Neither team suggested to me that the prospect of intelligence interest in the communications of a Prime Minister was too fanciful a prospect to be worth considering, although it may be that the two teams have different examples in mind of why it is not. However, I detected a developing sense on both Front Benches that the conflict issue might be one for the “too difficult” box.

I will not divide the House, but I close with these questions to the Minister: is it the Government’s position that the Prime Minister, uniquely among members of the Government, should have a veto over the interception of his own communications in circumstances in which the normal authorisation and approval criteria have been met? If so, why? If not, what answer do they have to the issue of conflict of interest?

[Lord Carlile of Berriew (CB)]

My Lords, it is a pleasure to follow that brilliant exposition by my noble friend of the problem that he tries to deal with in Amendment 40. After yesterday’s slightly more tense proceedings in this House, I have had a pleasant afternoon supporting the Government. In that spirit, I wish briefly to add some words to what has been said by my noble friend.

The notion of conflicts of interest is not a difficult one. Lawyers dealing with extremely complex cases have to deal with that problem more or less every day. It is something with which we are familiar. The notion that a Prime Minister could face a conflict of interest is not ludicrous. If we just look at the way in which proceedings have proceeded so far in the Covid inquiry, for example, we know that the most intense examination is now given to past communications. We are in a different age from the era when Prime Ministers did not use social networking. We are coming to a period when there will be a Prime Minister whose youthful exchanges with his or her friends will be available to public inquiries in the years to come. It is easy to imagine circumstances in which conflicts of interest might occur. For example, there could be conflicts of interest arising from kinship, as my noble friend Lord Anderson mentioned. Conflicts of interest could arise from earlier employment or from books and articles that person has written. We recently had a Prime Minister who has written quite a lot of interesting books but certainly provoked some interest of another kind when he was Prime Minister.

I urge the Minister not to brush aside this issue of conflict of interest, because it could happen, and it is better to anticipate these things than to leave them till later. I ask the Government to take seriously Amendment 40, for the reasons that have been given by the noble Lord, Lord Anderson, so we can return to this matter before the Bill is passed.
