Keir Starmer has been plunged into a fresh political crisis after Defence Secretary John Healey resigned over a bitter row about funding for Britain’s armed forces.
Healey, one of Labour’s most experienced and respected figures on defence, stepped down after warning that the Government’s Defence Investment Plan did not go far enough to keep the country safe at a time of rising global threats. His resignation has sent shockwaves through Westminster and placed renewed pressure on Starmer’s leadership.
In his resignation letter, Healey said the Prime Minister had been unable, and the Treasury unwilling, to commit the level of resources needed to defend Britain properly. He argued that the plan presented to him fell short of what was required, especially in the crucial early years when the armed forces need to improve readiness and rebuild capability.
The dispute centres on how quickly defence spending should rise. Starmer has promised a major uplift in military funding and insists his Government is delivering one of the biggest sustained increases since the Cold War. However, critics say the plan moves too slowly and fails to meet the urgency of the moment.
According to reports, the settlement offered to the Ministry of Defence would take spending to around 2.68 per cent of GDP by 2030, while many defence voices have argued Britain needs to reach 3 per cent much sooner. Healey is said to have concluded that he could not remain in post if the plan forced him to make decisions that might reduce military readiness or increase risk to personnel.
The resignation is particularly damaging because Healey had long been seen as a loyal Labour figure rather than a rebel. His departure therefore carries extra weight and makes the row look less like routine political disagreement and more like a serious warning from inside the Government.
The crisis deepened further after other defence figures also raised concerns, adding to the sense that Starmer is struggling to hold his team together. The timing could hardly be worse, with Britain preparing for important international defence discussions and allies watching closely to see whether the UK is serious about rebuilding its military strength.
Downing Street has defended the Prime Minister, insisting the country is safer because of decisions he has made and that the Defence Investment Plan will deliver the capability the armed forces need. Government sources also argue that difficult spending choices are being made across departments to support the military.
But politically, the damage is clear. Opposition parties have seized on the resignation as evidence that Starmer’s Government is losing control. Conservatives say the Prime Minister has no credible plan, while critics across Westminster argue that national security should not be delayed by Treasury caution.
The row also comes at a fragile moment for Starmer personally. His premiership has already faced pressure over public spending, Labour unrest and speculation about Andy Burnham’s possible return to Westminster. A Cabinet-level resignation over defence now adds another major test.
For voters, the issue goes beyond internal Labour drama. Defence spending touches on the basic question of whether Britain is prepared for an increasingly dangerous world. With war in Europe, instability in the Middle East and pressure on NATO allies to do more, questions about military readiness are becoming more urgent.
Healey’s resignation has therefore turned a funding dispute into a national security row. Starmer must now show that his Government can protect the country, reassure allies and restore confidence inside his own party.
If he fails, this defence crisis could become one of the most serious blows to his authority yet.
