LONDON – Britain’s agreement to transfer sovereignty of the Chagos Islands, home to the strategically significant U.K.-American military base on Diego Garcia, is currently on indefinite hold. This development follows the withdrawal of support for the deal from the Trump administration, significantly complicating the diplomatic landscape between the U.K. and the U.S.
The British government acknowledged on Saturday that the necessary legislation to ratify the agreement has run out of time in Parliament. This situation marks a significant setback in ongoing discussions regarding the future of the islands and reflects the deteriorating relations between Prime Minister Keir Starmer’s government and the Trump administration.
Initially, President Trump expressed support for the deal, but in a sudden policy shift in January, he referred to the transfer of the islands as “an act of GREAT STUPIDITY” through a social media post. Following this reversal, the U.K. government found itself in a position where it had to pause the bill’s progression, eventually conceding that it would not become law before the current parliamentary session concludes in a few weeks.
As it stands, the deal is not expected to be included in the legislative agenda announced by King Charles III for the next parliamentary session commencing on May 13. Despite the frustration stemming from the U.S. administration’s change of stance, British officials remain hopeful that the agreement can eventually be revived.
“Diego Garcia is a key strategic military asset for both the U.K. and the U.S.,” the British government stated. “Ensuring its long-term operational security is and will continue to be our priority — it is the entire reason for the deal.”
The government emphasized that it would only proceed with the deal if it maintains U.S. support, which currently seems uncertain. Simon McDonald, former head of Britain’s Foreign Office, remarked that the government “had no other choice” but to put the deal on hold, indicating that the current hostility from the U.S. necessitated a reevaluation of the terms.
The strategic military base located on Diego Garcia has played a pivotal role in U.S. military operations, supporting engagements from Vietnam to Iraq and Afghanistan. In the context of escalating geopolitical tensions, the base is viewed as essential for maintaining military readiness and operational capabilities.
Under the provisional agreement reached between the U.K. and Mauritius, the British government would lease the Diego Garcia base for a duration of at least 99 years. This arrangement was intended to protect the base from legal challenges and address concerns raised by international bodies, including the United Nations, which has urged the U.K. to return the islands to Mauritius.
Opposition parties in the U.K., including the Conservative Party, have expressed strong reservations about the agreement, arguing that relinquishing control of the islands could expose them to potential interference from nations such as China and Russia. They have called on the Trump administration to retract its support for the deal.
The situation is further complicated by the plight of the Chagossians, the indigenous people displaced from their homes in the 1960s and 1970s to facilitate the military base’s establishment. Many of the estimated 10,000 displaced Chagossians and their descendants now reside mainly in Britain, Mauritius, and the Seychelles, having long fought for recognition and the right to return to their homeland.
