Defence Investment Plan

Mike Martin Excerpts

Tuesday 30th June 2026 Commons Chamber

[Dan Jarvis]

My hon. Friend is right to raise those concerns about the threat we face every single day from cyber. In my previous role, I spent a lot of time ensuring that we were co-ordinated across Government—across the Cabinet Office, the Home Office and other Government Departments. This defence investment plan provides the resource to make sure that we have the right capabilities to meet the emerging threat that we are dealing with on a daily basis. Cyber is a key part of that threat. What I have done is refocus and sharpen some of the capabilities in order to be able to deploy them sooner than would otherwise have been the case. There is always a balance between the shorter and the longer term, but I am confident that this plan gives us the right capabilities when we need them.

This is a tale of two DIPs. The first DIP is covered by the period in the current spending review, up to about 2030, and the second DIP is the bit beyond that, from 2030 to 2035. The first has detailed spending commitments, and the latter has quite vague spending commitments. The former has small investments and the latter has big investments. I will give two examples: air has £28 billion versus £70 billion, and land has £19 billion versus £36 billion. On behalf of the Government, whoever might be in it by that point, can the Secretary of State confirm to the House that the Treasury has guaranteed that those figures will be in the next spending review—that is, that the Defence section of the next spending review has already been written?

[Dan Jarvis]

With great respect to the hon. Gentleman, it is not for me to make guarantees on behalf of other Government Departments, including the Treasury. I am sure that he will understand that. I do not think that any Minister outside the Treasury would be in a position to make that guarantee.

I know that the hon. Gentleman thinks carefully about these matters, so the guarantee that I can give him is that in the time I have had available, I have looked very carefully at the mix of capabilities contained within the plan and made a number of changes in order to deliver capabilities that I thought were required sooner rather than later. Has that involved making some difficult choices? Yes, it has. Has it involved cutting some capabilities? Yes, it has. But what I have to do is do right by defence and be satisfied that we have the resource available and the right capabilities in place to allow us to operate alongside our allies in a very dangerous world.

That is not an easy process, as I hope the hon. Gentleman will acknowledge. I hope he will also acknowledge that today’s investment plan represents an important step forward, but as I have said consistently, there is still a requirement to spend more on defence.
