John Healey Resignation Exposes UK Defence Funding Shortfall and Military Decline
Former Defence Secretary John Healey's resignation letter criticises the UK's unpublished Defence Investment Plan (DIP), stating it "falls well short of what is required for defence and the country at this dangerous time." He explicitly blamed Prime Minister Sir Keir Starmer's perceived unwillingness and the Treasury's reluctance to commit necessary resources.
The DIP, which outlines funding for equipment and infrastructure over the next decade following the June 2025 Strategic Defence Review, reportedly targets an increase in defence spending to 2.68% of GDP by 2030. This represents a mere 0.08% rise from the existing 2027 commitment of 2.6% of GDP, equivalent to approximately £2.4 billion. Healey’s letter asserts the government should instead aim for 3% of GDP by 2030.
Decades of Military Contraction
Analysis reveals a stark decline in the UK's military capabilities since 1990. The Army's regular soldier numbers have plummeted from 153,000 to 73,790, narrowly above the 2025 Strategic Defence Review's recommended minimum of 73,000. Furthermore, applications for regular army enlistment fell by 40% in 2025 compared to 2024, and reservist numbers have dropped from 76,000 to 25,770.
The Royal Navy, once possessing 48 major combat ships in 1990 (13 destroyers, 35 frigates), now fields only seven frigates and six destroyers. Concerns over readiness were underscored by the protracted deployment of HMS Dragon to the Gulf to protect an RAF base in Cyprus. The Royal Air Force, with over 300 combat jets in 1990, now operates 107 Eurofighter Typhoons and at least 37 F-35 Lightning IIs, despite their technological superiority. The imperative for investment in uncrewed aircraft systems, or drones, is also highlighted, particularly given their increasing lethality in conflicts such as Ukraine.
Procurement and Expenditure Criticisms
The Ministry of Defence manages 47 of the 213 projects within the 2024-25 Government Major Projects Portfolio. The National Audit Office (NAO) reported in December that 12 of these projects were rated 'Red', signifying that their successful delivery "appears to be unachievable." The NAO further criticised the MoD's consistent failure to deliver projects on time, within budget, and to required performance standards, noting an average of six and a half years to award contracts for projects over £20 million. The 2025 Strategic Defence Review had recommended a "segmented approach" to procurement to deliver contracts within two years.
A government spokesperson claimed they are delivering on the Strategic Defence Review, backed by "the largest sustained increase in defence spending since the Cold War," with over £270 billion invested across this Parliament. However, this benchmark is notably low, as defence spending has been on a near-constant downward trajectory since the fall of the Berlin Wall. The UK's commitment to 2.5% of GDP for NATO-qualifying defence spending by April 2027 (2.6% including security and intelligence) and an "ambition" for 3% in the next Parliament falls short of the NATO target of 5% of GDP for "national security" by 2035.
Military analysts, including General Sir Richard Barrons, co-author of the 2025 Strategic Defence Review, argue that rising threats from Russia since 2022, the ongoing Middle East conflict, and uncertainties regarding US commitment to NATO necessitate significantly greater UK defence investment. Lord Robertson, who led the 2025 Strategic Defence Review, starkly stated, "We cannot defend Britain with an ever-expanding welfare budget," noting that spending on working-age benefits now surpasses defence expenditure and is projected to rise to 4.3% of GDP by the decade's end.
