Overview
- John Healey resigned as defence secretary on Thursday after publishing a letter that said the Defence Investment Plan financial settlement he was shown this week "falls well short" of what is needed.
- Healey and military advisers say the plan leaves a multibillion funding gap that officials have estimated at about £28 billion to 2030 while reported government uplift options have been roughly £13.5 billion to £15 billion.
- Reports show the settlement would lift defence spending to about 2.68 percent of GDP by 2030, a pace Healey called too slow and one he said would force choices that reduce operational readiness and increase risk to personnel.
- The resignation escalates pressure on Prime Minister Keir Starmer, follows other recent cabinet departures, and raises political stakes ahead of next week’s by-election and any potential leadership moves.
- The DIP remains unpublished but is expected before the NATO summit on July 7, and defence industry and oversight bodies warn continued delay and a smaller, backloaded settlement will hamper procurement, supplier planning and Britain’s credibility with allies.
