Defence Investment Plan

The forthcoming defence investment plan has been informed by a range of inputs and perspectives, including those of service chiefs. These contributions have been critical in delivering on the strategic defence review and in enabling the transformation within defence that is necessary as we move towards warfighting readiness.

I am a former Chief Secretary to the Treasury, and I have seen reports that service chiefs are drafting letters to the Secretary of State warning of their concerns about whether enough money is going into defence. When the delayed defence investment plan is produced, will it give clarity on when the Government will reach the critical 3% threshold? To be credible, the plan needs to distinguish between the start of the next Parliament, which will be in 2029, and the end of it, which will be in 2034. If the plan does not do that, no one will take the aspiration seriously.

I know that the right hon. Member has strong views on defence, as do I. As a Government, we are increasing defence spending, with £5 billion extra in our budget: it will be 2.5% of GDP by 2027 and 3% of GDP in the next Parliament. The strategic defence review will be implemented by the defence investment plan. That will set out what capabilities we are buying and how we can improve our warfighting readiness. He will have to wait a wee bit longer as the work continues to deliver that plan very soon.
