Question to the HM Treasury:

To ask His Majesty's Government what plans they have to publish a detailed plan to invest 3.5 per cent of GDP on core defence spending by 2035; and if so when.

On 30 June, the Government published the Defence Investment Plan (DIP), committing an additional £15bn over four years to defence spending. From 2027-28 onwards, the UK will spend 2.7% of GDP on core NATO defence spending, solidifying its position as the NATO Alliance’s third-largest cash spender, behind only the US and Germany.

The Government has committed to increasing defence spending to 3% of GDP in the next Parliament, with funding and plans to be set out at the next spending review. Alongside NATO allies, the UK has committed to reach 3.5% of GDP on defence spending by 2035. The UK remains committed to meeting its obligations to the Defence Investment Pledge. All Allies will review the trajectory and spend in 2029, when NATO next reviews its capability plans.
