The cork had been holding, barely.
In the long and turbulent history of governing parties consuming themselves from within, Britain's Labour government has arrived at a familiar and perilous juncture. Defence Secretary John Healey and Armed Forces Minister Carns resigned within hours of one another on Thursday, each declaring that Prime Minister Keir Starmer's military spending plan fell dangerously short of the nation's needs — a public verdict delivered by men with the credentials to make it sting. The resignations arrive as Starmer prepares to face NATO allies abroad, leaving him to defend a defence policy his own defence ministers have just abandoned. What began as internal party friction has hardened into something more consequential: a question, now spoken aloud in ministerial letters, about whether this prime minister can hold.
- Two senior ministers with direct military experience resigned on the same day, transforming a policy disagreement into a visible crisis of authority at the top of the British government.
- The timing was almost cruelly precise — Armed Forces Minister Carns defended the spending plan on live television, then resigned before the broadcast had finished, amplifying the sense of collapse.
- Starmer had designed the Defence Investment Plan as proof of his governing competence, but it became instead a public demonstration of his inability to carry his own cabinet.
- With the G7 summit days away and NATO counterparts waiting, the new Defence Secretary must now explain to allies why his predecessor quit over the very plan he is being asked to champion.
- Potential leadership challengers including Andy Burnham and Wes Streeting are watching closely, as the dissent that had been briefly suppressed resurfaces with ministerial weight behind it.
The truce was always fragile. After weeks of internal recrimination following Labour's poor electoral showing, the Makerfield by-election had briefly given the party something to focus on besides its own divisions. That reprieve ended on Thursday.
Defence Secretary John Healey resigned, telling Prime Minister Keir Starmer in direct terms that the government's newly unveiled military spending plan fell well short of what the country needed. The announcement had been intended as a showcase of Starmer's ability to deliver — instead it became a public rebuke, timed to inflict maximum damage.
The embarrassment compounded within hours. Armed Forces Minister Carns, a former soldier with deployments across four conflict zones, appeared on television that evening still defending the plan. He spoke of steadying the ship. Then he resigned. The spectacle of a minister abandoning a policy he had just defended on live television underscored something beyond mere disagreement — it suggested that senior figures inside the cabinet were already thinking past Starmer's tenure. Carns had even indicated, while still in office, that he would not avoid a leadership contest if one came.
The government had been working to construct a defence package that could satisfy the armed forces, hold the cabinet together, and eventually be sold to the public. It had failed at the first test. Other departments had already been warned to absorb cuts to redirect money toward defence, while the Conservatives called for welfare reductions to fund the military. Starmer was caught between pressures he could not fully reconcile.
With the G7 summit approaching and NATO meetings on the horizon, the newly appointed Defence Secretary Dan Jarvis would now face allied counterparts carrying the weight of his predecessor's resignation. Starmer's allies pointed to genuine governing difficulties — a sluggish economy, rising welfare costs, an unstable international environment. None of it changed the central fact: the prime minister had lost control of his own narrative at the moment he most needed to command it, and the window for recovery appeared to be narrowing.
The cork had been holding, barely. After a month of recriminations following Labour's disastrous election performance, the Makerfield by-election campaign had given the party something to focus on besides its own fractures. But the respite was always going to be temporary, and it lasted only as long as the headlines stayed elsewhere.
On Thursday, Defence Secretary John Healey walked away from his post. In his resignation letter to Prime Minister Keir Starmer, he was direct: the military spending plan the government had just unveiled fell far short of what the country actually needed to defend itself. It was a public rebuke, delivered at precisely the moment Starmer had hoped to project competence and forward momentum. The Defence Investment Plan was supposed to be a showcase—proof that unlike his internal rivals, the prime minister could actually deliver on his promises. Instead it became evidence of the opposite.
The embarrassment deepened within hours. Armed Forces Minister Carns, himself a former soldier with deployments across Northern Ireland, Kosovo, Iraq, and Afghanistan, appeared on television Thursday evening still holding his ministerial title. He spoke about steadying the ship, about doing his job. An hour later, he resigned too. The timing was almost theatrical in its bluntness—a minister defending a policy on live television, then abandoning it before the broadcast ended.
What made this particularly damaging was not just the resignations themselves but what they signaled about Starmer's grip on his own government. These were not backbench grumbles or anonymous complaints to journalists. These were senior figures, both with military credentials that gave them standing to speak on defence matters, saying publicly that the prime minister's judgment was wrong. Carns had even told an interviewer, while still in office, that if a leadership contest came, he would not shy away from it. The message was unmistakable: there were people in the cabinet already thinking about what came after Starmer.
Downing Street and the Treasury had been working the problem hard, or so they claimed. They said they were trying to construct a defence spending package that could satisfy the armed forces, convince their own ministers, and eventually sell to the public. They had failed on the first count. They were struggling on the second. They had not yet even attempted the third. Other government departments had already been told to expect cuts so money could flow to defence. The Conservatives were calling for welfare reductions to fund the military. The government was caught between competing demands it could not fully meet.
Starmer's potential successors—Andy Burnham, Wes Streeting, and others—were watching all of this unfold. They were watching a prime minister who had tried to use a major policy announcement to demonstrate control and vision instead preside over the public departure of two senior ministers who said he had got it wrong. He was due at the G7 summit in southern France in days, where his new Defence Secretary Dan Jarvis would have to face NATO counterparts and explain why Britain's defence minister had just quit over the government's own spending plan.
The prime minister's allies argued he was navigating genuinely difficult terrain: a sluggish economy, a high tax burden, rising welfare costs, an unstable world, and defence demands that seemed to grow by the week. All of that was true. But it did not change the fact that he had lost control of the narrative at a moment when he desperately needed to regain it. The dissent that had been temporarily suppressed was fizzing again at the top of the Labour Party, and this time it had ministerial weight behind it. Starmer would have to pick himself up and try once more to make the case for his premiership. But the window for doing so appeared to be closing.

Why did Healey resign specifically over the spending number rather than, say, disagreeing with the broader approach?
Because the number was the whole point. He was saying the prime minister had made a choice—a deliberate choice—to underfund defence. It wasn't a disagreement about philosophy. It was about whether the government was serious.
And Carns resigning an hour after defending it on television—was that planned, or did something shift?
The timing suggests something shifted in that hour. Maybe he saw the reaction. Maybe he talked to Healey. Or maybe he realized that going on air and then staying silent would make him complicit in something he couldn't live with.
What does this do to Starmer's authority with his own cabinet?
It signals that if you disagree strongly enough, you can walk. That's not necessarily fatal, but it means the next time he asks someone to defend an unpopular decision, they'll know resignation is an option.
The piece mentions potential successors watching. Is this actually a leadership challenge forming, or just normal Westminster jockeying?
It's the soil where challenges grow. No one's declared yet, but these resignations are oxygen for the people thinking about it. They show weakness. They show the prime minister can't hold his team together.
Could Starmer have avoided this by spending more on defence?
Probably. But then he'd have had to cut welfare or raise taxes further, and that creates different problems. He was trapped between bad choices and picked one that cost him his defence secretary.
What happens at the G7 now?
His new defence secretary has to walk into a room full of NATO allies and explain why his predecessor just quit over the government's own plan. That's not a conversation anyone wants to have.
