Defence Investment Plan

Tanmanjeet Singh Dhesi Excerpts

Tuesday 30th June 2026 Commons Chamber

[Madam Deputy Speaker]

I call the Chair of the Defence Committee.

[Mr Tanmanjeet Singh Dhesi (Slough) (Lab)]

I thank the Secretary of State for the ministerial briefing beforehand and for allowing Defence Committee members advanced sight of the defence investment plan. I also welcome that we now have a fully funded plan, backed by the Treasury, that is scalable for key facets such as housing, training, workforce recovery, AI, integrated air and missile defence, and munition stockpiles.

However, there is no clear pathway to reach 3% of GDP spend. Despite assurances that the DIP would go further than previous defence equipment plans, it actually contains less detail: there is no full 10-year expenditure plan; there is no breakdown between procurement and support costs; and much of the investment appears to be backloaded beyond 2030. Will my right hon. Friend commit to fight for more funding for defence, so we reach the 3% of GDP spend by 2030? Will he commit to building more in Britain to stimulate sovereignty and economic growth? What operational risks have been accepted in the interim while there have been cuts to investment in certain areas? When will our Committee be furnished with the full details, so that effective parliamentary scrutiny can be undertaken?

[Dan Jarvis]

I am grateful to the Chair of the Select Committee for the scrutiny that I know he will apply to this important piece of work. He reeled off a number of different capabilities, and I am very happy to discuss those with him in more detail.

The essence of my hon. Friend’s question was to seek an assurance that I will commit to fight for the funding that defence needs, and I will, of course, give him that commitment. It is my job now to ensure that we have the resources we need to field the kind of capabilities required to keep our country safe at a point of great challenge. That does involve working very closely with our NATO allies and providing them with the certainty of our long-term commitment towards defence funding, and it will require us to show a trajectory to our commitment to 3.5%.

He is also right to raise the point about backing Britain. The Prime Minister, the Chancellor and other ministerial colleagues have been absolutely clear that, while we require additional resource to provide the capabilities we need, we must do that in a way that ensures we are best able to grow our economy, and create and sustain good, well-paid defence jobs right around the United Kingdom. That is an absolute priority for me, and I give him an assurance that we will work closely with him on it.
