The United States government has clarified that there is “no pause” in the proposed Chagos Islands agreement, countering earlier remarks that suggested the United Kingdom was slowing legislation to transfer sovereignty of the archipelago to Mauritius.
The clarification comes amid heightened political debate in London and Washington over the future of the strategically significant islands in the Indian Ocean. While a UK minister had told Members of Parliament that the legislative process was being paused, a US government source indicated that no formal halt had been agreed upon and that timelines would be announced through regular channels. The statement signals continued coordination between the two allies despite political turbulence surrounding the agreement.
At the center of the discussion is the planned transfer of sovereignty of the Chagos Islands from the United Kingdom to Mauritius, coupled with a long-term lease arrangement allowing the UK and the United States to retain operational control of the military base on Diego Garcia. The arrangement seeks to resolve a long-standing sovereignty dispute while preserving Western military presence in a geopolitically sensitive region.
Structure of the agreement and legislative progress in the UK
Under the proposed deal, the UK will hand sovereignty of the Chagos archipelago to Mauritius while leasing back Diego Garcia for 99 years. The financial structure of the agreement outlines payments averaging £101 million annually over the lease period. The UK will pay £165 million in each of the first three years, followed by £120 million annually from years four through thirteen. Thereafter, payments will be indexed to inflation.
The legislation designed to formalize the agreement, known as the Diego Garcia Military Base and British Indian Ocean Territory Bill, is in the final stages of its passage through Parliament. It is currently under consideration in the House of Lords. Once enacted, the bill would enshrine the sovereignty transfer and lease arrangement into UK law, providing legal clarity and ensuring the continued operation of the joint UK-US military facility.
The Chagos Islands have been under British control for approximately two centuries and form part of the British Indian Ocean Territory. Mauritius has long contested UK sovereignty over the archipelago, arguing that the islands were unlawfully separated from it prior to independence. International legal opinions, including advisory findings from global bodies, have added momentum to Mauritius’s claims in recent years, prompting negotiations between London and Port Louis.
The Diego Garcia base holds strategic significance for both the United Kingdom and the United States. It serves as a vital hub for military logistics, surveillance operations and regional security missions. Preserving access to the facility has been a central priority in shaping the contours of the agreement.
Political tensions and criticism from Washington and London
Political controversy intensified after US President Donald Trump publicly urged UK Prime Minister Keir Starmer not to proceed with the deal. In a statement posted on his Truth Social platform, Trump warned against “giving away Diego Garcia,” calling the move detrimental to a close ally. He argued that the land should not be transferred and described the agreement as damaging to Western strategic interests.
Trump’s remarks appeared to contrast with earlier expressions of support from the US State Department, which had indicated official backing for the UK government’s plan. Following renewed scrutiny, the State Department declined to elaborate further, stating that it had nothing additional to add after comments made in the House of Commons.
In the United Kingdom, critics of the agreement have voiced concerns over national sovereignty and security. Opposition Conservative Party leader Kemi Badenoch argued that Britain should not pay to surrender territory it has administered for generations. Skeptics contend that transferring sovereignty could expose the islands to geopolitical maneuvering by rival powers such as Russia or China, particularly in a region of growing strategic competition.
Supporters of the deal counter that the lease arrangement ensures uninterrupted military access while addressing longstanding legal and diplomatic disputes with Mauritius. They argue that resolving the sovereignty issue strengthens the UK’s international standing and aligns policy with legal obligations. The 99-year lease is presented as a mechanism to safeguard security interests while honoring Mauritius’s claim.
The debate reflects broader questions about the balance between historical territorial control and modern diplomatic realities. For the UK government, the challenge lies in maintaining its strategic alliance with the United States, managing domestic political opposition and responding to international legal pressures.
As legislative procedures continue in the House of Lords, attention remains fixed on the final outcome. The US government’s insistence that there is no pause suggests that, at least at the diplomatic level, momentum remains intact. Whether political resistance in either country alters the trajectory of the agreement will depend on parliamentary deliberations, executive decisions and evolving geopolitical calculations in the Indian Ocean region.
