John Healey quits after accusing Prime Minister Keir Starmer and the Treasury of underfunding defense amid growing threats from Russia, uncertainty over the GCAP fighter program, and mounting pressure on NATO allies to boost military spending.
LONDON | British Defense Secretary John Healey resigned Thursday in a dramatic protest against the U.K. government's defense spending plans, warning that inadequate funding could weaken military readiness, increase risks to deployed personnel, and undermine Britain's ability to respond to growing security threats.
The resignation marks one of the most significant political and defense policy setbacks for Prime Minister Keir Starmer's government and comes as NATO allies prepare for a critical summit next month in Turkey, amid ongoing concerns about Russian aggression and European defense preparedness.
In a sharply worded resignation letter, Healey criticized the government's long-awaited Defense Investment Plan (DIP), arguing that the funding package fails to provide the resources needed to address an increasingly dangerous security environment.
"You have been unable, and the Treasury has been unwilling, to commit the resources that the nation needs to defend the country at this time of rising threats," Healey wrote to Starmer.
The departing defense secretary said he could not support a spending plan that would force difficult choices affecting operational readiness and force modernization.
"Without a DIP that meets the moment in this way, I am being forced to make decisions that would reduce the readiness of our forces and increase the risk to personnel on operations, and could make the country less safe," he wrote.
