My Lords, I offer my thanks to the noble Lords, Lord Anderson of Ipswich, Lord Fox, and Lord West of Spithead, and the noble and learned Lord, Lord Hope of Craighead, for their amendments and for the points that they have raised during this debate. I also thank the noble Lord, Lord Evans, for his perspective, and the noble Lord, Lord Carlile, for supporting the Government, which obviously I hope becomes a habit.
I have discussed the triple lock at length with noble Lords and many others in Parliament and across government. We are all in agreement that this is a matter of the utmost importance, and it is imperative that we ensure that the triple lock operates correctly. That means that the triple-lock process, when needed urgently, has the resilience to continue in the most exceptional circumstances, when the Prime Minister is genuinely unavailable, while ensuring that the alternative approvals process is tightly and appropriately defined.
On Amendment 40, I thank the noble Lord, Lord Anderson, for the valuable engagement he has taken part in with my ministerial colleagues, Home Office officials and me regarding this amendment. I take this opportunity to explain why the Government do not support this amendment. The expressed intention of the noble Lord’s amendment is twofold: first to tighten the requirement in the current clauses, which use the word “unavailable”; and, secondly, to introduce a potential provision for dealing with a conflict of interest, as one of the circumstances in which the alternative approvals process could be used.
There is certainly merit in limiting the circumstances in which the alternative approvals process may be used. However, the noble Lord’s amendment introduces the requirement for a judgment to be made on the Prime Minister’s ability to consider a warrant application, for any number of reasons, including conflict of interest. This raises a number of challenges.
The first challenge is that “unable” draws into the legislation the principle of ministerial conflict of interest. This poses a constitutional tension and a challenge to Cabinet hierarchy. The inclusion of “unable” would allow for someone other than the Prime Minister to decide whether the Prime Minister is subject to a conflict of interest in a particular scenario, which goes against clear constitutional principles regarding the Prime Minister’s powers. This would be a subjective decision on the Prime Minister’s ability, rather than an objective decision on his availability.
As such, rather than strengthening the current drafting, the amendment as proposed could be considered to constitute a watering down of the triple lock, in that it was always designed to be exercised by the Prime Minister. Someone else making a decision about whether the Prime Minister is able to make a decision, given they can be said to be available and therefore technically able to consider an application, risks the intention of the triple lock. As drafted, the original clauses require a binary decision to be made about whether the Prime Minister is available or not, whereas, in deciding whether the Prime Minister may have a conflict of interest, a judgment must be made which is not binary and therefore has much less legal clarity.
The noble Lord, Lord Anderson, asked me if it is right that the Government believe that it is proper for the Prime Minister to consider a warrant application relating to the Prime Minister’s own communications. The best answer I can give is that the Bill is intended not to tackle issues relating to Prime Ministerial conflicts of interest, but rather to improve the resilience of the warrantry process. Conflict of interest provisions and considerations relating to propriety and ethics are therefore not properly for consideration under this Bill. The Prime Minister is expected, as are all Ministers, to uphold the Nolan principles in public life. For these reasons, the Government cannot support this amendment.
The Government have, however, recognised the concerns expressed by Members of both Houses, and the seeming consensus that a more specific, higher bar should be set with relation to the circumstances in which the alternative approvals process may be used. This high bar is of particular importance because of the seriousness of using these capabilities against Members of relevant legislatures. We accept that we are not above the law and it is appropriate for it to be possible for us to be subject to properly authorised investigatory powers. However, it is right that the significance that this issue was given in the original drafting of the Investigatory Powers Act is respected, and the communications of our fellow representatives are properly safeguarded.
I therefore thank the noble Lord, Lord West of Spithead, for his amendments, and for the close engagement on this Bill which I, the Security Minister and my officials have had with the members and secretariat of the Intelligence and Security Committee. Following engagement with Members of both Houses on these amendments, it is clear that there is good consensus for these measures, and the Government will not be opposing them today. While they will reduce the flexibility of the current drafting somewhat, the Government agree that these amendments strike an important and delicate balance between providing the flexibility and resilience that the triple-lock process requires, while providing the legal clarity and specificity to allow for its effective use. The amendments will also provide further confidence to members of relevant legislatures, including those of this House, that the protection and safeguarding of their communications is of paramount importance.
I should note that the Government do not quite agree with the precise drafting of these amendments, and we expect to make some clarifications and improvements in the other place, particularly to the
references to routine duties under Sections 19 and 102 of the Investigatory Powers Act 2016, but I am happy that we seem to have reached broad agreement today.
