Defence row exposes tensions over how to keep UK safe

The defence of the nation is traditionally seen as the foremost responsibility of a prime minister. However, Sir Keir Starmer is currently facing criticism from two departing defence ministers who accuse his government of failing to provide adequate resources to fulfill this fundamental duty. This dispute raises an important question: is the government genuinely falling short in ensuring the country’s security, or is this conflict simply another contentious and poorly managed disagreement over defence spending within Whitehall?

Presently, the UK government allocates approximately £66 billion towards defence, funding the armed forces which continue to command respect on the global stage. This budget also sustains the country’s nuclear deterrent. The UK benefits from its geographic protection—being an island nation—and the strength of its international alliances, all factors contributing to national security. Historically, however, successive governments have had difficulty maintaining consistent defence funding. Post-Cold War reductions and a failure to increase the defence budget in response to rising global threats have led to a smaller and less equipped military.

Critiques of the Ministry of Defence point to repeated procurement failures, with new equipment often delayed and over budget. Internal disputes between government departments, particularly between the Treasury and the MoD, have not been effectively managed, with neither No 10 nor the Cabinet Office exhibiting enough control to resolve these ongoing tensions. The current disagreement is occurring against a backdrop of a rapidly shifting global security environment. The focus of threats has shifted from non-state militant groups to state actors like Russia and Iran, heightening the urgency to rethink defence priorities and spending.

The evolving nature of warfare further complicates the picture. Traditional heavy armour and large naval vessels may be less relevant in modern conflicts, where technological advances such as drones, cyber warfare, and space capabilities are increasingly vital. Meanwhile, the United States has signaled that it expects European NATO members to increase their defence contributions, pushing them to meet agreed spending targets without relying on American subsidies. In response to these pressures, the UK government has pledged to increase defence spending from 2.3% of GDP last year to 2.5% next year, and later to 3.5% by 2035. The prime minister has acknowledged this necessity, emphasizing at the Munich security conference the need to “spend more faster.”

Despite ambitious promises, doubts remain about the government’s willingness to allocate sufficient funds to fulfill these commitments. Justin Crump, CEO of the Sibylline risk intelligence firm, criticized the government by stating, “The government is not prepared to put its money where its mouth has been.” The anticipated “defence investment plan” aimed to enable the implementation of the strategic defence review’s objectives, but earlier warnings from defence chiefs revealed a £28 billion shortfall over four years just to meet existing obligations. This revelation caused friction between the Ministry of Defence, No 10, and the Treasury, who had assumed current budgets were sufficient for these plans.

Subsequently, the figure was negotiated down to roughly £13 billion, a compromise that did not satisfy John Healey, who resigned in protest. Healey expressed serious concerns about reductions in military readiness and increased risks to personnel, writing to the prime minister that these cuts could compromise national safety. He argued strongly in his resignation letter: “I am certain that a headmark date for 3% of GDP on defence in 2030 is what Britain must set. This commitment would have strong cross-party support. Other European allies are stepping up in this way.” Furthermore, intelligence assessments suggesting a potential Russian attack on NATO as early as 2030 have led some defence officials to argue that defence spending should in fact be doubled.

The government’s indecision and budgetary uncertainty have had tangible consequences. Defence suppliers face financial difficulties, with some struggling or going bankrupt amid halted contracts. Each military branch contends with unpredictability over future equipment acquisitions and resource allocations. While investments in the nuclear deterrent and collaborative initiatives such as the Aukus submarine program may be preserved, questions remain about the army’s deployment of new AI targeting systems, the navy’s uncrewed vessels, and the RAF’s acquisition of advanced fighter jets. Stockpiles of missiles and munitions, many of which have been provided to Ukraine, also risk running low.

This situation raises broader concerns about the military’s preparedness for future conflicts. Al Carns, in his resignation letter, lamented that “We are still purchasing capability suitable for the last war while our adversaries arm for the next one.” Key priorities include acquiring drones and integrated air defence systems capable of countering threats similar to those seen in Ukraine and the Gulf region.

With defence decisions pending, the UK’s international standing and credibility are at stake. The new Defence Secretary, Dan Jarvis, is set to meet NATO counterparts in Brussels, where allies expect clarity on Britain’s defence plans amidst its slipping spending and capability targets. In the upcoming NATO summit in Turkey, the prime minister will confront fellow leaders—including former US President Donald Trump—to outline the UK’s defence commitments. These discussions are likely to prove challenging as Britain seeks to navigate a complex and rapidly changing security landscape
