Defence Investment Plan confirmed for publication ahead of NATO summit as Chancellor vows “more money spent more effectively”

Homeland June 26, 2026

Rachel Reeves has pledged the long-awaited Defence Investment Plan will be released before the NATO summit opens in Ankara on 7 July, amid political turbulence at the top of government and mounting pressure from industry and military leaders for adequate funding.

Chancellor Rachel Reeves has confirmed that the UK’s Defence Investment Plan (DIP) will be published before the NATO summit in Ankara, Turkey, which opens on 7 July, describing it as a document that will “meet the scale of the challenges we face” and deliver “more money spent more effectively” across the armed forces.

The announcement came as Reeves told the Commons she had met with Defence Secretary Dan Jarvis and Chief of the Defence Staff Richard Knighton to discuss the plan’s final shape. Her statement follows weeks of high-profile political turbulence around the DIP, including the resignation of former Defence Secretary John Healey and armed forces minister Al Carns earlier this month. Healey told Prime Minister Keir Starmer, who announced his own resignation on Monday, that the funding on offer “falls well short of what is required for defence and the country at this dangerous time.”

Deputy Prime Minister David Lammy also confirmed the timeline, telling MPs: “I can confirm that the DIP will be published before the NATO summit. And I think it is important that the prime minister is in post for that NATO summit.”

The scale of the dispute over funding has sharpened focus on what the DIP will ultimately deliver. Conservative MP Rebecca Smith challenged Reeves in the Commons over reports that the Treasury had offered only a 0.08% increase in defence spending by 2030, a figure she described as “pitiful” in the face of growing global threats. She also raised the issue of SME access, telling the House that “innovative defence small and medium-sized enterprises are effectively locked out of MoD contracts and denied the opportunity to scale their capabilities.” Reeves pushed back, describing the government’s commitment as “the biggest uplift in defence spending since the end of the Cold War” and adding that contracts would be “awarded to firms here in Britain to keep our country safe.”

Reports have also suggested that Andy Burnham, who is positioning himself as a successor to Starmer, would prefer the DIP to be delayed until he enters Downing Street. Nominations for a new party leader are not due to open until 9 July, after the NATO summit has concluded, meaning Starmer is expected to remain in post for the plan’s publication.

For UK defence supply chain businesses, the DIP’s imminent publication represents a pivotal moment. The plan is expected to set out how increased defence investment will be allocated across capability areas, procurement programmes, and the industrial base, providing the strategic framework against which suppliers at every tier can plan their engagement. The emphasis from ministers on awarding contracts to British firms, and the Parliamentary debate around SME access, suggests that industrial participation and supply chain breadth will be central themes.

Relevant capability areas for businesses seeking to engage with DIP-driven procurement include:

• Defence SME supply chain development and prime contractor engagement
• Land, air and naval platform manufacture and sustainment
• Enabling technologies, communications and cyber capability
• Maintenance, repair and overhaul services
• Logistics and defence infrastructure support
• Research, development and technology innovation
• Resilient supply chain management and procurement compliance
