Overview
- John Healey resigned as defence secretary on June 11, saying the settlement he was shown 'falls well short' and warning it could make the country less safe.
- Healey publicly blamed the Prime Minister and the Treasury for refusing to commit the resources the MoD requested, turning a budget dispute into a major political challenge for the government.
- The Ministry of Defence reportedly sought roughly £28 billion extra over four years while the government prepared an uplift in the roughly £13.5–18 billion range, with critics saying the cash is backloaded and too slow.
- Two other MoD figures left or complained about the plan and rapid ministerial replacements have been made, but Downing Street says the Defence Investment Plan will be finalised and published before the NATO leaders' summit on July 7.
- Military chiefs and oversight bodies have warned of gaps in munitions, drones and maintenance that risk readiness, and the row raises questions about the UK’s credibility with allies and political stability ahead of a high‑profile by‑election.
