UK Defence Secretary John Healey Resigns Over Military Spending Dispute with PM Starmer

Jun 11, 2026

UK Defence Secretary John Healey and Armed Forces Minister Al Carns resigned over a dispute with PM Keir Starmer on military spending. Healey accused Starmer of failing to commit resources to counter rising threats, stating a plan to raise spending to 2.68% of GDP by 2030 fell short of the needed 3%. The resignations weaken Starmer's authority ahead of key G7 and NATO summits and fuel speculation of a leadership challenge.

Healey resignation over defence spending

▪UK Defence Secretary John Healey resigned on June 11, 2026, over a dispute about military spending.
▪In his resignation letter, Healey accused PM Keir Starmer and the Treasury of being "unable" and "unwilling" to commit necessary defence resources.
▪Armed Forces Minister Al Carns also resigned on June 11, 2026, stating the spending plans were "not built for the threat we face."
▪Healey stated he could not accept a Defence Investment Plan (DIP) settlement that he believed fell "well short of what is required."
▪Security Minister Dan Jarvis was appointed as the new Defence Secretary following John Healey's resignation.

Defence investment plan funding dispute

▪By comparison, Germany plans to spend 3.7% of its GDP on defence by 2030, while France is set to spend 2.5%.
▪The Ministry of Defence reportedly requested an additional £28 billion over four years, while the final offer was around £13.5 billion.
▪The government's proposed plan would raise defence spending to 2.68% of GDP by 2030, after reaching 2.6% next year.
▪PM Keir Starmer defended the plan, stating it would be funded in a "sustainable and fair" way without "irresponsible borrowing."
▪John Healey argued that UK defence spending must reach 3% of GDP by 2030 to adequately meet current threats.

Cabinet infighting within Labour government

▪In a February 2026 speech in Munich, Keir Starmer had vowed to "spend more, faster" on defence to counter the threat from Russia.
▪Greater Manchester Mayor Andy Burnham is reportedly seeking a return to Westminster to potentially challenge Keir Starmer for the premiership.
▪The resignation is a significant blow to Prime Minister Keir Starmer's authority and has fueled speculation about a leadership challenge.
▪The dispute over the Defence Investment Plan (DIP) caused months of severe infighting within the Labour government.

Military readiness concerns from chiefs

▪Retired General Richard Barrons said the government's failure to fund its own review diminishes the UK's standing within NATO.
▪Former chief of the defence staff Gen Nick Carter stated it is now "very difficult" for Britain to punch above its weight in defence.
▪Healey warned the proposed funding would force decisions that reduce the readiness of UK forces and increase risks to personnel on operations.
▪The dispute follows a warning from UK intelligence that Russia could attack a NATO country as early as 2030.

Upcoming G7 NATO summit timing

▪The timing leaves PM Starmer facing the prospect of explaining the resignation to international allies at the upcoming summits.
▪The resignations occurred days before a G7 summit in France and weeks before a NATO summit in Ankara, Turkey.
