My Lords, I am delighted that the noble Lord, Lord Butler of Brockwell, moved his amendment. It received support from around the House and I am pleased to say that the Government are in a position to accept it. In Committee, the noble Lord, Lord Butler, and my noble friend Lord Lothian made the important point that the committee should be independent. I agree wholeheartedly. It will submit its report, not a draft of its report, to the Prime Minister, who may insist on redactions to the document but may not insist on any other changes. Again, I agree with this, so we are happy to accept the amendment.
Amendment 27 would have the effect of changing the grounds on which the Prime Minister might exclude any matter from a report to Parliament. It would add to the grounds for exclusion already described so that material might be excluded if it were of such a nature that it would be prejudicial to the continued discharge of the functions of the security service, the Secret Intelligence Service, the Government Communications Headquarters or any person carrying out activities that fall within Section 2(2); if it were sensitive information as defined in paragraph 4 of Schedule 1; or if it were information that, in the interests of national security, should not be disclosed. For convenience, I will refer to the three possible grounds for excluding material as the prejudice to functions ground, the sensitive information ground and the national security ground. The amendment would also require that matters considered to fall under the prejudice to functions ground—currently the only ground for excluding information from the Bill—should be set out in a memorandum of understanding.
The ISC must be able to report candidly to the Prime Minister on sensitive matters. Inevitably, it will not always be possible to publish the full content of its reports because of the nature of the material contained in them. I do not think that there is any dissent in the House from that position. It follows that there must be an ability to redact information before ISC reports are published or laid before Parliament. In Committee, and amendment was tabled by the noble Baroness, Lady Smith—to which she referred—which would have made the criteria for excluding material from the
published report just the grounds of sensitive information and national security. The noble Lord, Lord Rosser, who is not in this place, explained that it was a probing amendment to try to find out why it was necessary to use the definition that was in the Bill rather than that in the amendment, which presented grounds similar to those in Schedule 1 for withholding information from the ISC. In the case of withholding material from the ISC, both grounds had to be fulfilled, whereas for these purposes material could be excluded from a report if either ground were fulfilled.
The sensitivity of information and national security grounds add nothing in substance. Material that falls within those grounds will necessarily also fall within the prejudice to functions grounds—unless in the case of sensitive information that is so historical or so widely known publicly that it is no longer sensitive, in which case there would be no real justification for excluding it from an ISC report to Parliament anyway.

The test in the Bill is modelled on the one contained in the Intelligence Services Act 1994. It has worked well and is well understood by the committee and the Government. It has allowed material to be excluded where it should be excluded, but it has also allowed the Government and the ISC to ensure that as much of the ISC's reports that can be published are published. It is also not appropriate to require that matters considered to fall within the prejudice to functions
ground should be set out in a memorandum of understanding. It would be impossible to describe the sorts of matters that would meet that test in an exhaustive way.
As previously noted, this criterion has worked well throughout the history of the committee. One reason for that, no doubt, is its inherent flexibility. The nature of the material that might need to be excluded from the published reports of the ISC will vary over time, and the precise consequence of the disclosure of such material may also vary.
I hope in the context of my explanation that the noble Baroness will understand why I ask her not to press her amendment.
