Starmer’s Defence Plan: A Step Towards NATO’s Spending Goals?

UK’s Defence Spending: A Strategic Shift

The UK government has unveiled its long-awaited Defence Investment Plan (DIP), with Prime Minister Sir Keir Starmer calling it a “historic shift” for the nation’s defence strategy.

The DIP outlines a significant increase in defence spending, aiming to address the country’s security needs and international commitments.

NATO-Qualifying Defence Spending: The Key Metric

The focus is on NATO-qualifying defence spending, which includes not only the Ministry of Defence’s budget but also state spending on military pensions and other related areas.

In 2025, the UK’s NATO-qualifying defence spending was estimated at £70bn, representing 2.4% of GDP.

Sir Keir’s Commitment: A Progressive Increase

Sir Keir has pledged to raise this spending to 2.5% of GDP by 2027 and further to 2.6% by including the activities of security and intelligence agencies.

He also set a “clear ambition” to reach 3% of GDP in the next parliament, aligning with NATO’s long-term goals.

The Hague Summit: A Collective Commitment

At the 2025 Hague Summit, NATO members agreed to a 5% GDP target for defence and security, with 3.5% dedicated to “core defence” by 2035.

Sir Keir’s DIP aims to reach 4.2% of this commitment, a significant step towards NATO’s vision.

The DIP’s Impact: A Mixed Reception

The DIP has faced scrutiny, with former Defence Secretary John Healey resigning over concerns about its effectiveness.

Healey argued for a 3% GDP target by 2030, while the DIP projects 2.7% by 2030, leaving questions about the trajectory to NATO’s 3.5% goal.

However, the government maintains that the DIP is a significant step forward, with additional funding and a clear plan for the future.

A Balanced Approach: Defence and Diplomacy

The UK’s commitment to NATO’s spending targets is a strategic move, ensuring the nation’s defence capabilities are robust and aligned with international partners.

As the DIP unfolds, the government’s ability to balance defence spending with other priorities will be a key focus, ensuring a comprehensive approach to national security.
