Prime Minister Keir Starmer said defence is the number-one priority for the upcoming spending review in the United Kingdom.

The move signals a strategic shift in fiscal priorities as the government seeks to address political pressure over military readiness and global security threats. By prioritizing the armed forces, the administration aims to modernize capabilities amid an ongoing debate over national spending limits.

Reports indicate the government is preparing for one of the most significant defence spending increases since the Cold War. Some reports suggest Starmer may approve a package valued at $24 billion [1]. Other reports place the potential increase at £18 billion [2].

Starmer said these comments during a series of engagements in London, including a meeting with police and a media briefing. The specifics of the priority shift were reported on May 15, 2026 [3].

The spending review comes at a time when the UK military faces pressure to maintain a credible deterrent and operational capacity. The administration has not yet finalized the exact figures, but the commitment to prioritize defence suggests a willingness to allocate funds away from other domestic sectors to meet security goals.

Government officials said that bolstering the armed forces is essential for national stability. The upcoming review will determine how these funds are distributed across the Navy, Army, and Royal Air Force to ensure the UK remains a key player in international security.

This prioritization suggests that the UK government is pivoting toward a 'security-first' fiscal policy. By potentially allocating between £18 billion and $24 billion to the military, the Starmer administration is attempting to balance domestic economic constraints with the necessity of maintaining a strong geopolitical presence, likely in response to evolving threats in Europe and beyond.
