Overview
- Senior ministers said the long‑delayed Defence Investment Plan is close and will be published in weeks rather than months, but no firm date has been set.
- Press reporting places a large funding shortfall at about £28 billion while internal proposals centre on packages of roughly £18 billion or smaller offers of £12–15 billion.
- The Treasury has resisted loosening Chancellor Rachel Reeves’s fiscal rules to cover the uplift which has left a funding dispute between the Ministry of Defence and HM Treasury.
- Conservative MPs plan a Commons vote on June 2 to force a timetable for publication and NATO allies expect a clear UK commitment before the summit in early July.
- Defence firms and military leaders warn the uncertainty is harming contracts, jobs and readiness and analysts at the Institute for Fiscal Studies say the government must choose between cuts, tax rises or unsustainable borrowing.
