UK’s PM Starmer: U.S. Use of Bases Was in the UK’s National Interest

Prime Minister Keir Starmer announced on March 1, 2026, that the UK would permit the U.S. to use British military bases for "limited defensive" strikes against Iranian missile sites, framing the decision as a measure to protect British lives and national interests. The move, which followed months of U.S. requests, authorizes the use of facilities such as RAF Fairford in Gloucestershire and Diego Garcia in the Indian Ocean. Starmer emphasized that the UK would not participate in offensive actions against Iran but would support defensive operations to counter Iranian missile threats.

The decision aligns with the UK's legal rationale of "collective self-defence" under international law, as outlined in a government statement. Starmer cited the need to prevent Iran's "scorched-earth strategy," including attacks on airports, hotels, and military bases in the Gulf, which endanger British citizens and allies. At least 200,000 British nationals are estimated to be in the Middle East, prompting urgent protective measures.

Political reactions were mixed. Conservative leader Kemi Badenoch criticized the government for hesitancy, while Liberal Democrat leader Ed Davey called for parliamentary approval of the U.S. base usage. U.S. President Donald Trump remarked that the UK's delay in granting permission was unprecedented between the two nations.

The UK's stance reflects a balancing act between security imperatives and avoiding escalation. Defence Secretary John Healey clarified that the UK does not endorse the legality of U.S.-Israeli strikes on Iran but shares the goal of preventing Iran from acquiring nuclear weapons. Meanwhile, the government is preparing contingency plans, including potential evacuations of British nationals if regional airspace remains unstable.

This decision underscores the UK's strategic alignment with the U.S. in countering regional threats while navigating domestic political and legal scrutiny. Investors may monitor its impact on geopolitical stability, energy markets, and insurance risks in the Middle East.
