My Lords, I am grateful to the noble Lords, Lord Butler and Lord Campbell-Savours, and the noble Baroness, Lady Smith, for introducing these amendments, three of which concern the ISC’s ability to oversee operational matters and the fourth concerns the relationship between the ISC and Select Committees. It is worth reminding ourselves that one of the purposes of the Bill is to extend the ISC’s statutory remit. It makes clear its ability to oversee the operational work of the security and intelligence agencies and of other parts of the Government’s intelligence machinery.
With this formalisation, we certainly expect that the ISC will provide such an oversight on a more regular basis. The provisions of the Bill allow the ISC to consider,
“any particular operational matter but”—
as the noble Lord, Lord Butler, quite properly indicated by quoting from the Bill—
“only so far as the ISC and the Prime Minister are satisfied that … the matter … is not part of any ongoing intelligence or security operation, and … is of significant national interest”.
The starting point is that the ISC’s oversight in this area ought to be retrospective and, so as not to cut across the role of Ministers, should not involve, for instance, prior knowledge of approval of agency activity. It is important that when there is an ongoing operation, or indeed a future operation, the responsibility for national security lies with Ministers. The noble Lord, Lord Butler, made it clear that the ISC is not seeking to intervene in that and accepts that the primary and principal responsibility lies with Ministers.
The ISC’s consideration of an operational matter must also,
“be consistent with any principles set out in, or other provision made by, a memorandum of understanding”.
The first amendment would have the effect of leaving it solely to the judgment of the ISC to decide when the criteria for considering a particular operational matter are met. It is our intention that the memorandum of understanding will set out the factors that should be taken into account in assessing whether a particular operation is still ongoing or is of significant national interest. None the less, while fully accepting that the committee does not have ambition or aspiration to extend beyond what is said, I am sure that even reasonable people could come to a different view about whether those particular criteria are met or not in a particular instance.
I hope that noble Lords will agree that the judgment as to whether an operational matter meets the criteria is one that should properly be for both the ISC and the Government and not just for one or the other. It is important that the judgment is got right; I do not think that anyone is suggesting in any way whatever that there will be any deliberate attempt to intrude in circumstances where it has not previously been anticipated that the ISC should, but the last thing that anyone wants is for a different judgment to be struck that could lead to impeding the operational effectiveness of the intelligence agencies.
The noble Lord, Lord Butler, indicated what was perhaps at the crux of his concern. He mentioned the case of Libya. I understand that there may be a concern that the requirement that both the ISC and the Prime Minister should be satisfied that the criteria are met will slow down responses to more routine requests from the ISC for information about operational matters. The noble Lord used the word “cumbersome”. I assure your Lordships’ House that that is not the Government’s intention, nor do we believe that it will be the effect of the clause. However, I further assure your Lordships that we are looking very closely at this and it may well be that a memorandum of understanding to be agreed by the Government and the ISC is the right vehicle for agreeing a process that will allow the
information that the noble Lord indicated to be provided to the committee, and in an appropriately prompt manner. Alternatively, it may be that there are other approaches that might make the position clearer, and I suspect that as this Bill progresses through Parliament we may return to it. But I indicate that it is a matter to which we will give further consideration. It may be that the memorandum of understanding is a better way to address it—and I hope that, on that basis, the noble Baroness will not press that amendment.
The noble Lord, Lord Campbell-Savours, said that he would wish to remove one of the key restrictions on the ISC’s new power to oversee agency operations—namely, the requirement that its oversight of operations should be retrospective. There is nothing in red in my briefing, but there is an indication that the amendment should be resisted. We have worked with the current committee to develop the new arrangements, and it is the committee’s view, as the noble Lord, Lord Butler, made clear in his speech to his amendment, that the committee agrees with the Government that it should not oversee ongoing operations.
There are clear lines of ministerial responsibility for authorising agency operations, and we believe that they could be undermined by the ISC having prior, even contemporaneous, knowledge of particular operations. Secondly, once a particular operation has commenced, it may well be that things move very quickly, and it is essential that the agencies can focus fully on the task on hand. It is better to bring the committee in and have retrospective oversight of a particular operation. Indeed, some operations will be so sensitive, with perhaps highly sensitive sources in play, that the details are kept within a very small, need-to-know circle, even within the agencies. The committee fully understands this; it is part and parcel of the work that it does, and which it recognises that the agencies do on our behalf. Once an operation has concluded, the ISC will then be well placed to carry out its work, which will no doubt include making strategic and policy recommendations, and giving views on any lessons learnt. The noble Lord’s concern expressed in Committee, which he has reflected this evening, on how operations might be defined, particularly if there is a long-running set of activities, was whether that could be defined by the Government as a single operation. I certainly understand where the noble Lord is coming from, but that is not an appropriate or proper interpretation of the clause. The nature of operations varies, and this is one of the reasons why we have provided in the Bill detailed consideration as to how the ISC’s operational oversight remit should operate and should be set out in a memorandum of understanding, which the Government will agree with the ISC.
