Sir Keir Starmer is expected to unveil a multi-billion pound defence investment package aimed at strengthening the UK’s armed forces and defence industry. The long-delayed plan could be published within days after months of disagreement inside Government over funding levels.
The proposed package, reportedly worth £18 billion over four years, comes at a politically sensitive moment for the Prime Minister. According to The i Paper, allies believe Starmer is determined to secure a lasting political legacy as questions continue over his leadership and growing internal Labour tensions.
The investment plan is designed to support recommendations from the Strategic Defence Review published last year. It would also increase the UK’s military readiness amid rising international instability and mounting pressure from NATO allies to raise defence spending.
Officials have linked the package to wider security concerns, including Russia’s growing activity around Europe and continued tensions involving Iran. The Government is also seeking to strengthen defence ties with European allies and maintain relations with the United States ahead of the next NATO summit.
Delayed Defence Blueprint Expected to Unlock Billions in Military Contracts
The Defence Investment Plan was originally expected last autumn but was delayed following disagreements between senior ministers over how much funding should be allocated. According to The Times, two options were discussed inside Government: a £12 billion package and a larger £18 billion proposal.
Defence Secretary John Healey and National Security Adviser Jonathan Powell are said to have supported the higher figure, while Chancellor Rachel Reeves reportedly resisted the increase. The i Paper reports that Starmer is now pushing to finalise the plan despite earlier divisions inside Whitehall.
The proposed funding would support several major defence programmes, including upgrades to RAF Typhoon fighter jets and the purchase of F-35A aircraft capable of carrying nuclear weapons. The package would also back new contracts with defence manufacturers across the UK.
If approved at the higher level, the spending increase would move Britain closer to spending 3 per cent of GDP on defence by the end of the current Parliament. Starmer had previously pledged to reach 2.5 per cent by April 2027 and 3 per cent during the following Parliament.
The delay in publishing the strategy has drawn criticism from opposition parties and defence companies. According to the same source, industry figures argue that uncertainty around future investment has complicated planning for both manufacturers and the armed forces at a time when several European countries are increasing military spending.
Leadership Pressure Shapes Timing of Security Announcement
The expected announcement comes during a difficult period for Starmer’s leadership. Labour has faced internal unrest following calls from more than 100 MPs for the Prime Minister to resign, alongside the departure of former Health Secretary Wes Streeting and other ministers.
A source cited by The i Paper said Starmer “doesn’t feel like he has anything to lose” and wants to leave behind a political legacy. The report also noted that concerns over potential leadership rivals, including Greater Manchester Mayor Andy Burnham, have added urgency to the Prime Minister’s timetable.
Foreign policy has become one of the central areas where Starmer’s Government argues it has achieved results. Under his leadership, the UK has strengthened relations with European NATO allies including France, Germany and Poland.
The Government has also attempted to balance its relationship with US President Donald Trump while avoiding direct involvement in the conflict with Iran. According to the same source, publication of the defence strategy could help ease tensions with Washington before the NATO summit in Ankara later this year. The plan is expected to be published ahead of the Makerfield by-election on 18 June, where Burnham is widely viewed as a strong contender.
