UK government blocks Trump from using British bases to strike Iran

The United Kingdom government has refused to grant permission for the United States to use British military facilities for any potential strike on Iran, amid escalating tensions over Tehran’s nuclear programme.

The decision places London in a cautious diplomatic position as indications emerge that US President Donald Trump is considering military options that could involve installations located on British territory.

Reports indicate that American officials are preparing operational strategies that would depend on the joint US-UK military base at Diego Garcia in the Chagos Archipelago, as well as RAF Fairford in Gloucestershire. RAF Fairford functions as a major centre for the deployment of US heavy bombers across Europe.

Under existing defence agreements between both countries, American forces require prior approval from the British government before launching operations from UK soil. However, reports state that such authorisation has not been granted should Washington proceed with military action against Iran.

Sources within government circles attribute the hesitation to legal concerns. British authorities fear violating international law, which holds both direct actors and supporting states accountable if a military strike is later judged unlawful.

The matter reportedly featured in a telephone discussion between President Trump and UK Prime Minister Rishi Sunak on Tuesday night. Trump’s ultimatum to Iran regarding its nuclear ambitions formed a key part of the conversation.

A day later, the US president criticised the UK government’s stance on the Chagos Islands agreement. He also referenced Iran in a post on his Truth Social platform, where he suggested American forces might need access to the bases if Tehran refuses negotiations.

“Should Iran decide not to make a Deal, it may be necessary for the United States to use Diego Garcia, and the Airfield located in Fairford, in order to eradicate a potential attack by a highly unstable and dangerous Regime,” Mr Trump wrote.

He added that such a move would aim to prevent “an attack that would potentially be made on the United Kingdom, as well as other friendly countries,” suggesting that British involvement could fall under self-defence if Iran poses a direct threat.

Meanwhile, the UK government has reaffirmed its commitment to moving forward with the Chagos Islands agreement despite signals of unease from Washington.

Justice Minister Alex Davies-Jones confirmed that the necessary legislation will return to Parliament once scheduling allows. The proposed bill had earlier been withdrawn from debate in the House of Lords after a Conservative-backed amendment called for a pause, citing “changing geopolitical circumstances.” Fresh delays were also reported as a possibility.

The situation highlights growing diplomatic strain as Britain attempts to preserve its strategic alliance with the United States while addressing legal and political sensitivities tied to any direct role in a potential conflict with Iran.
