In February 2025 Sir Keir committed to raising Nato-qualifying defence spending to 2.5% of GDP by 2027.
The prime minister also announced that the activities of the UK’s security and intelligence agencies would – by 2027 – be classified as Nato-qualifying defence spending. As a result spending would hit 2.6% of GDP by 2027.
The prime minister also stated a “clear ambition” to increase spending to 3% of GDP “in the next parliament”.
At a Nato summit in the Hague in June 2025 the UK and other members committed to spend 5% of GDP on defence and security with 3.5% going to Nato-qualifying “core defence” by 2035.
The alliance’s members agreed that the rest of the 5% (1.5% of GDP) could be made up of spending to “protect critical infrastructure, defend networks, ensure civil preparedness and resilience, innovate, and strengthen the defence industrial base”.
Sir Keir said on Tuesday that the measures in the DIP “takes us to 4.2% under that commitment”.
