Chancellor John Healey has told every government department to find 1% cuts in their capital budgets to fill a £4.7bn hole in the funding of the Defence Investment Plan. These reductions stack on top of a previous 1% capital squeeze demanded earlier this year, which funded the initial £10.3bn slice of the plan’s overall £15bn price tag.
The Funding Gap and Capital Squeezes
The latest fiscal maneuver leaves government departments scrambling to decide what long-term infrastructure projects will hit the chopping block. Capital budgets govern long-term investments rather than day-to-day departmental operations. Earlier reductions forced the cancellation of several major road improvement schemes, and officials now expect similarly painful trade-offs across public infrastructure.
The £4.7bn shortfall directly threatens the trajectory of the Defence Investment Plan. While the package successfully boosts overall defense outlays, the chancellor faces mounting skepticism over how the Treasury intends to hit the government’s target of spending 3% of national income on defense by 2030, followed by 3.5% of GDP by 2035.
Political Crossfire and Opposition Reaction
Conservative leader Kemi Badenoch attacked the chancellor during parliamentary exchanges, accusing him of offering “a plan to have a plan” and quipping, “I bet [Vladimir] Putin’s really scared now.” Badenoch argued that Healey was failing his own tests on national security, pointing out that the administration had omitted concrete funding mechanisms from the recent Budget statement.
Healey defended his approach to the House of Commons on Wednesday, telling MPs that meeting the long-term targets would involve “looking hard at public spending.” He confirmed that comprehensive details on reaching the 3% target by 2030 and 3.5% by 2035 would be unveiled during next year’s spending review.
Internal friction compounds the political pressure. Earlier this year, Healey resigned as defense secretary after accusing then-Prime Minister Sir Keir Starmer of shortchanging the armed forces. Now holding the purse strings as chancellor, he insists he is getting work under way to meet NATO commitments in a fiscally sustainable way.
International Approval and Parliamentary Warnings
Despite domestic opposition, NATO Secretary General Mark Rutte offered public backing, stating that the UK remained on “a credible path towards meeting the commitment made by all Nato Allies in The Hague – to ensure we’re all investing what’s needed to remain ready & able to deter aggression and defend our freedom and security.”
Yet domestic misgivings persist within parliament. Tan Dhesi, Labour MP and chair of the Commons defence committee, warned that key decisions had been postponed. “There is a cost to inaction,” Dhesi said. “Investment in our nation’s defence and security cannot be kicked into the long grass.”
Innovative Financing and Fiscal Realities
To bridge the massive funding divide without relying solely on painful departmental cuts, Healey outlined several alternative funding streams. The Treasury has started treaty negotiations with Finland, Poland, and the Netherlands to establish a multilateral defense mechanism enabling allies to pool resources. Additionally, the government aims to expand public-private partnerships to draw in private capital.
As part of these structural shifts, the National Wealth Fund and British Business Bank have received directives to channel £5bn into defense, dual-use technology, and sovereign capability. However, the Office for Budget Responsibility estimates that hitting the 3.5% GDP target by 2035 will ultimately cost £35bn.
Helen Millier, director of the Institute for Fiscal Studies, questioned the efficacy of relying heavily on private investment. “Increasing investment in defence companies may contribute to the target but it is unclear how much this will lead to an increase in UK defence capabilities,” Millier noted, adding that reaching 3% of GDP will likely require direct top-ups to spending totals.
