LONDON, June 12 (Parliament Politics Magazine) – The United Kingdom’s approach to military spending faced a sharp rebuke from former armed forces minister Al Carns, who labeled the government’s defence plans as both underfunded and outdated.
His resignation on Thursday night followed hours after the departure of his superior, Defence Secretary John Healey, marking a period of intense internal turmoil for Prime Minister Sir Keir Starmer.
The disputes centered on the government’s long-delayed defence investment plan, which became a source of significant friction between the Ministry of Defence and the Treasury. While the Ministry of Defence sought 18 billion pounds over four years to address rising security threats, the Treasury signaled a willingness to provide only 13.5 billion pounds, with only 10 billion pounds identified as new funding.
Concerns over military readiness
Carns, a former Royal Marines Colonel who entered Parliament in 2024, utilized his exit to highlight what he views as a critical disconnect between the current procurement strategy and the realities of modern warfare. He argued that the existing plan fails to account for the innovative, rapid-deployment technologies that have reshaped the conflict in Ukraine.
During an interview on the BBC’s Today programme, Carns explained his reasoning for leaving the front bench.
He stated, “I didn’t think the funding settlement was correct for defence, and I didn’t agree with the defence investment plan, which I thought was looking at how to fight the last war rather than the next one.”
His critique suggested that the government remains too committed to legacy systems ordered by the Conservative party years ago. He advocated for making difficult decisions to phase out these older platforms in favor of more modern, innovative solutions. His departure highlighted a growing tension in Whitehall between career bureaucrats and those with recent frontline experience regarding the speed of military decision-making.

Political Blows for Starmer
The double resignation of Healey and Carns has created a significant administrative challenge for the Prime Minister. Healey, in his own resignation letter, noted that the government had been unable to commit the necessary resources to defend the nation amidst a period of rising global threats.
Starmer has maintained that his administration is prioritizing both economic growth and military strength, arguing that an irresponsible approach to spending would ultimately harm the economy. Business Secretary Peter Kyle defended the government’s position on Sky News, stating that the investment plan would be published before the upcoming Nato summit and insisting that the administration remains committed to a sustainable path forward.
Despite the criticism, Carns maintained a respectful tone toward the Prime Minister personally. He described Starmer as an honest and integral individual but expressed frustration over the internal fighting required to secure funding for the fundamental duty of protecting the nation.
The fallout from these resignations has sparked immediate speculation regarding potential challenges to the current leadership. When asked about his own political future, Carns declined to rule out a bid for the Labour leadership should a contest emerge. As the government works to stabilize the Ministry of Defence following the appointment of Dan Jarvis as the new Defence Secretary, the debate over how to balance fiscal discipline with national security requirements is expected to remain a central issue.
