Prime Minister Keir Starmer is set to publish a long-delayed Defence Investment Plan (DIP) ahead of the NATO summit scheduled for July 7 in Turkey, amid ongoing cabinet debates over the plan’s financing. The announcement comes after several months of postponements and internal disagreements about the scale of the defence spending increase and its impact on other government departments.
The DIP will outline the funding strategy for new equipment and defence infrastructure over the next decade, following last year’s broader strategic defence review. Starmer confirmed the plan during a visit to a defence contractor in Wiltshire and emphasized that it would include a further increase in defence expenditure. However, he did not dismiss the possibility of budget cuts to other areas of government spending to accommodate the enhanced defence commitments.
Reports suggest the investment package may have been reduced by as much as £3 billion following discussions between Starmer and Chancellor Rachel Reeves, although the Prime Minister described the plan as “another step up” in military investment, highlighting its necessity in the current geopolitical climate.
The delay in publishing the DIP has drawn criticism from several quarters. Shadow Defence Secretary James Cartlidge characterized the postponement as detrimental to national security and the defence industry, insisting that the government’s hesitation is “completely unacceptable” given the increasing global uncertainty. Similarly, Tan Dhesi, chairman of the defence select committee, reiterated the importance of clarity for the military and defence sector regarding future priorities and funding.
Concerns about security threats were underscored by statements from Chief of the Defence Staff Air Chief Marshal Sir Richard Knighton, who described the current environment as the most dangerous he has experienced in his career. Addressing the evolving challenges posed by Russia’s actions, Sir Richard stressed the need to make strategic decisions on defence priorities and investments. He highlighted the growing significance of drones and autonomous systems in future conflicts, areas where the UK must enhance its capabilities.
The upcoming publication of the DIP comes as NATO allies face pressure, particularly from the United States under President Donald Trump, to increase defence spending. Britain’s delay in revealing its defence strategy ahead of the summit had raised questions about its commitments to collective security.
As Starmer moves to finalize the plan, the government faces the complex task of balancing defence priorities with broader fiscal responsibilities, with opposition voices calling for decisive action to ensure the United Kingdom’s military readiness in an increasingly volatile global context.
