[Lord West of Spithead]

43: Clause 21, page 41, line 29, leave out “is unavailable to decide whether to give approval under subsection (2)” and insert with “is unable to decide whether to give approval under subsection (2), due to incapacity or inability to access secure communications”
Member’s explanatory statement
This amendment would specify that the only exceptional circumstances in which the Prime Minister would be permitted the use of a designate is when he or she is unable to make a decision due to incapacity (ill-health) or lack of access to secure communications.

[Lord West of Spithead (Lab)]

My Lords, this is the first of three amendments I have tabled to Clause 21 relating to the so-called triple lock for targeted interception and targeted examination of communications relating to Members of the relevant legislatures. These changes are replicated in the three amendments which I have laid to Clause 22, which we will come to later, which relate to the triple lock around the targeted equipment interference warrants.

The communications of Members of the relevant legislatures, including noble Lords in this House, should not be intercepted and read unless it is absolutely essential to do so in the most serious of circumstances. That is why Parliament added a third layer of safeguards to approve of any such warrant in the IPA, ensuring that these warrants will not only be issued by a Secretary of State and reviewed by a judicial commissioner but approved by the Prime Minister personally. This is a robust and necessary oversight mechanism, and it is important that any changes as a result of this Bill do not undermine the central three layers of approval.

Nevertheless, the ISC recognises that, on occasion, the requirement that a warrant be approved by the Prime Minister personally may disproportionately affect the operation of the intelligence agencies, where they are seeking a targeted interference or equipment interference warrant that is very time sensitive. We therefore support the intention to provide some resilience, whereby in truly exceptional circumstances, an appropriately empowered Secretary of State may temporarily deputise for the Prime Minister on these matters. However, the clauses before us go too far.

My three amendments seek to ensure that decisions are delegated only in the most exceptional circumstances, that the decision may be designated only to a limited number of Secretaries of State who are already responsible for authorising relevant warrants, and that the Prime Minister retains oversight of all warrants which have been authorised in their name through a retrospective review of the decision.

The first of those relates to the circumstances in which a decision may be delegated by the Prime Minister to a Secretary of State. This should be clearly defined and limited only to situations where the Prime Minister is genuinely unable to take a decision. My amendment specifies that the Prime Minister must be “unable”, rather than simply “unavailable”—which is a rather subjective test—to decide whether to give the necessary approvals. It sets out that the only situations in which this applies are due to incapacity or inability to access secure communications—for example, if the Prime Minister is extremely ill or is abroad and unable to securely access the relevant classified documentation. This provides what the agencies require, but, when combined with the requirement that there is an urgent need for the decision, also provides the necessary assurance to Parliament that the Prime Minister’s responsibility will be deputised only in specified exceptional circumstances, and ensures that the use of a delegate does not become routine.

My second amendment to Clause 21 is to specify those Secretaries of State who can act as a designate for the Prime Minister in these circumstances. As currently drafted, the Bill includes all Secretaries of State as potential designates for the Prime Minister in relation to triple-lock warrantry. However, only a limited number of Secretaries of State have any statutory responsibility for warrantry for investigatory powers: for example, the Secretaries of State for the Home Office, the Ministry of Defence, and the Foreign, Commonwealth and Development Office. Given that the authorising of a warrant that relates to a Member of the relevant legislature must be taken seriously, it is both sensible and desirable that any Secretary of State deputising for the Prime Minister on these matters should already be familiar with the process and framework for targeted interception and targeted equipment interference warrants as part of their routine responsibilities, as those are the warrants we are talking about.

This amendment therefore limits the Prime Minister to up to two designated Secretaries of State and specifies that they should be Secretaries of State who are already required in their routine duty to issue warrants under Sections 19 or 102 of the IPA. I note that my noble friend Lord Coaker has tabled a similar amendment, which would list a number of specific Secretaries of State who could be designated as deputies to the Prime Minister. We wholeheartedly support the intention behind this amendment, and our amendment seeks to achieve a similar outcome. However, I note the possible scenario whereby the evolution of departmental names, seen relatively recently with the renaming and restructuring of the Foreign, Commonwealth and Development Office, may sow confusion as to which Secretaries of State are included under Clause 21. My amendment seeks to avoid any such confusion by linking the role to existing statutory responsibilities for warrantry in the original Investigatory Powers Act. In this way, it should achieve a very similar outcome to that which was wisely proposed by my noble friend Lord Coaker.

My third amendment to Clause 21 would ensure that the Prime Minister retains ultimate responsibility for any targeted interception and targeted examination warrants which involve communications to or from Members of the relevant legislature. As I outlined earlier, the Intelligence and Security Committee considers it essential that the three planks of the triple lock not be weakened by any changes made by the Bill. Therefore, we must ensure that the Prime Minister’s overall oversight of and involvement in these warrants is retained, even if, in designated cases, it could be retrospective. I have therefore tabled an amendment to provide that the Prime Minister review the decision taken by a designated Secretary of State on their behalf as soon as the circumstances have passed which prevented the Prime Minister approving the warrantry in the first place.

--- Later in debate ---

[Lord West of Spithead (Lab)]

My Lords, I absolutely support what my noble friend has said. I was about to leap up and say that this should not be discussed in this forum because some of it is so sensitive. The Minister handled it extremely well, but we are getting quite close to the margins.

[Lord Sharpe of Epsom (Con)]

I thank both noble Lords for their thanks. I have forgotten where I was, but I had pretty much finished.

[Lord West of Spithead (Lab)]

I beg leave to withdraw my amendment.

Amendment 43 withdrawn.
