Keir Starmer is digging his heels in. Following a chaotic 24 hours that saw both Defence Secretary John Healey and Armed Forces Minister Al Carns quit his cabinet, the Prime Minister made it clear he has no intention of walking away.
The double resignation has pushed Downing Street into a full-blown crisis, exposing a massive rift over how much cash the UK should pour into its military. Critics say the government's defence spending plans leave the country vulnerable during a highly volatile period in global politics. Meanwhile, rivals within the Labour Party are already circling, sensing a chance to challenge for the top job.
But Starmer isn't backing down. He insists that staying on is a matter of duty, not stubbornness, and he's ready to fight to keep his position.
The Resignations That Shook Downing Street
The crisis kicked off when John Healey unexpectedly resigned as Defence Secretary. In a scathing letter to the Prime Minister, Healey didn't hold back. He claimed that Starmer and the Treasury were "unwilling" to commit the resources needed to protect the nation at a time of rising global threats, including the conflict involving Iran and Russia’s ongoing war in Ukraine.
According to Healey, the long-delayed Defence Investment Plan would only see defence spending creep up from 2.6% of GDP next year to 2.68% by 2030. Army chiefs had asked for an extra £28 billion to modernise forces and ensure operational readiness. Healey revealed that the Treasury’s offer amounted to roughly £13.5 billion, less than half of what military leaders say is required. He argued this layout would force decisions that reduce the readiness of British forces and put personnel on operations at a higher risk.
Hours later, Armed Forces Minister Al Carns, a high-profile former Royal Marine, followed Healey out the door. Carns publicly stated that the UK government hadn't learned the lessons of the Ukraine war and that funding choices shouldn't boil down to a simple battle between "welfare or warfare."
Starmer Defends the Numbers
Speaking to the BBC, Starmer hit back at the criticism and defended his administration’s spending choices. He pointed out that since Labour took office in 2024, the government has delivered the highest sustained increase in defence spending since the Cold War. To fund those initial boosts, No. 10 had to make the controversial decision to cut the international aid budget.
Starmer rejected the idea that the upcoming Defence Investment Plan leaves the UK unprotected. He argued that the plan offers sustainable, long-term funding that gives the private sector and the British defence industry the certainty they need to invest and modernise.
"I have taken the difficult decisions to make sure that we are safe as a country, because that is my number one priority," Starmer stated.
The Prime Minister also stressed that he won't fund military expansion through extra borrowing, though Number 10 hasn't ruled out future tax rises. He promised that defence will be treated as the top priority in the next formal spending review before the end of the current Parliament.
A Direct Challenge to His Leadership
The timing of these resignations couldn't be worse for Starmer. His authority was already shaky after his Health Secretary resigned just two weeks prior. To add to the pressure, the Labour Party recently agreed to let Greater Manchester Mayor Andy Burnham seek a return to Parliament, a move widely seen as setting the stage for a future leadership challenge.
Conservative Leader Kemi Badenoch seized on the chaos, claiming Starmer's premiership is actively falling apart. She accused the Prime Minister of underfunding the military to appease backbenchers who want to protect welfare spending.
Despite the mounting internal pressure and the threat of a formal leadership challenge, Starmer remains defiant. He told reporters that if a challenge happens, he will fight it head-on. t
He insists his decision to stay in Downing Street is driven by a deep sense of service and national stability. Plunging the country into a chaotic leadership election right now, he argues, is the last thing the UK needs.
What Happens Next
The fallout from this cabinet walkout leaves the government facing immediate practical hurdles.
- Appointing New Leadership: Starmer must quickly fill the vacant roles at the Ministry of Defence to restore stability to national security operations.
- Publishing the Defence Investment Plan: The government needs to release the delayed document to show the public and the defence industry exactly where the money is going.
- Managing the Next Spending Review: The Treasury will have to balance the intense pressure for higher military budgets against tight fiscal rules and competing domestic demands.
The Prime Minister is betting that a firm stance on fiscal discipline will look more responsible to voters than giving in to every funding demand. But with war in Europe and growing instability globally, the debate over whether the UK is spending enough to defend itself isn't going away anytime soon.
