Prime Minister Keir Starmer has told MPs he wants a long-delayed British defence and security investment plan published ahead of the Nato summit scheduled for June in The Hague. The announcement marks the first time the government has publicly committed to a specific timeline for releasing the review, which unions and opposition members have criticised for causing uncertainty across the defence sector.
PM Signals Timeline Before Nato Leaders Meet
During Prime Minister's Questions on Wednesday, Starmer confirmed the publication window without giving an exact date. He told the House of Commons the plan would be released "well before" the 25 June summit where alliance members will discuss defence spending commitments and joint capabilities. The review was originally expected last autumn but has faced repeated delays amid broader Treasury spending reviews.
The statement comes as Nato member states face mounting pressure to meet the alliance's revised defence spending target of 2.5 percent of GDP. Britain currently spends approximately 2.3 percent of its economic output on defence, placing it among the higher-spending members but still short of the newer benchmark.
Eight-Month Delay Draws Criticism From Unions and MPs
The defence investment review was first announced in October last year. Eight months on, contractors, unions, and parliamentary select committees have demanded clarity on planned procurement schedules, infrastructure spending, and workforce commitments. Unite, one of Britain's largest trade unions representing defence workers, called the silence "unacceptable" and warned that uncertainty was already affecting recruitment and plant investment decisions.
Conservative defence spokesperson James Cartlidge told reporters the government had "no excuse" for the delay, pointing to the strategic importance of Nato's eastern flank and ongoing conflicts in Europe. "Our allies need to know Britain is serious about its commitments," he said.
Why the Review Matters for Defence Industry
The review covers planned spending across several programmes including the AUKUS nuclear submarine partnership, the National Shipbuilding Strategy, and upgrades to the Army's infantry vehicles. Defence manufacturers have said they cannot commit to hiring decisions or supply chain investments without knowing the government's forward budget position. Industry body ADS Group warned in a March letter to the Prime Minister that the gap was damaging Britain's competitiveness in tender processes with France and Germany.
African Development Angle: What Nato Spending Means for the Continent
The Nato summit will bring together leaders from 32 member states at a time when European defence budgets are expanding rapidly following Russia's invasion of Ukraine. For African nations, this shift carries significant implications. As European powers redirect capital toward conventional military capabilities, development assistance budgets face pressure. Several African countries that rely on European security partnerships and peacekeeping funding are watching closely.
Nigeria, which maintains bilateral defence cooperation agreements with Britain, has expressed interest in what the expanded Nato investment posture means for existing training and intelligence-sharing arrangements. The UK's Gulf of Guinea security programme, worth around £40 million annually, has previously drawn on defence expertise from ministries directly affected by the domestic spending review.
South Africa's defence sector has also benefited from European partnerships, with British and French firms competing for naval modernisation contracts. Analysts in Lagos note that Britain's ability to honour its international commitments depends heavily on the investment decisions now sitting inside the delayed review.
Government Defends Approach Amid Political Pressure
Defence Secretary John Healey defended the timeline, saying ministers were ensuring the review aligned with the Treasury's broader fiscal update scheduled for late May. "We are not going to publish something half-baked that locks in the wrong priorities for a decade," he told journalists outside the Ministry of Defence. The Treasury has previously indicated that any defence spending increases would need to be funded through efficiency savings elsewhere in the budget.
Senior civil servants at the Ministry of Defence have declined to comment on specific programme timelines, citing the ongoing nature of the review process. Internal documents seen by the BBC suggest at least three major procurement programmes are currently in limbo pending publication of the strategic framework.
What Happens Next at the Summit
Nato's June summit will be the first under the alliance's new regional plans approved in 2023, which commit members to pre-positioned equipment and faster deployment timelines. The British review is expected to address how much additional capability Britain will contribute to these plans beyond its current commitments in Estonia and the North Sea.
Alliance sources say the United States has pushed European members to present concrete spending plans before the summit. Secretary-General Mark Rutte has warned that delays in national reviews risk undermining the alliance's credibility during a period of heightened strategic competition.
Starmer is expected to hold a bilateral meeting with US President Donald Trump at the summit, where the defence spending question will feature prominently. American officials have made clear they expect Nato's European members to move toward the 2.5 percent target quickly.
Watch List: Key Dates in the Coming Weeks
Defence industry analysts are watching for two key dates: the Treasury's spring fiscal statement due on 23 May, and a potential ministerial statement to Parliament the following week if the review is finalised in time. MPs on the Defence Committee have requested a private briefing with officials before any public announcement.
The Unite union has scheduled a meeting with Ministry of Defence representatives for next month and has warned it will escalate industrial action if the review fails to provide "meaningful commitment" to workforce numbers. Employees at several British shipyards and aerospace factories have been on standby notices since January.
The publication of the review, expected within weeks, will determine whether Britain enters the Nato summit with a clear spending blueprint or faces awkward questions from allies about its long-term defence priorities.
