The deal, which was intended to transfer sovereignty of the Chagos Islands to Mauritius while re-leasing the strategic Diego Garcia military base, has effectively stalled as the UK runs out of time to pass the required legislation before Parliament is dissolved.According to the BBC, officials made it clear that the agreement had not been completely abandoned, but they acknowledged that the main legal requirement, the formal exchange of messages from the United States, had not yet been completed.
US support for uncertainty stalls legislation
The agreement, signed in May 2025, initially received American support. However, tensions rose after Trump publicly criticized the plan, calling it an “act of complete weakness” and urging the UK not to “abandon Diego Garcia.”Despite previous support from the US State Department, the lack of official confirmation has prevented the UK from moving forward. A government spokesman stressed that the deal would only go ahead with US approval, adding that ensuring Diego Garcia’s long-term security remained “the whole reason for the deal.”
As reported by the BBC, a government spokesperson said: “Diego Garcia is a key strategic military asset for both the UK and the US. Ensuring its long-term operational security is and will continue to be our priority – that is the whole reason for the deal.”He added: “We still believe that the agreement is the best way to protect the base’s long-term future, but we have always said that we will not move forward with the agreement unless it has the support of the United States.”
The spokesman added: “We are continuing to engage with the United States and Mauritius.” The proposed arrangement would see the UK pay around £101 million a year to lease the base, a major British-American military asset in the Indian Ocean.
Strategic and political concerns dominate the debate
The Chagos Islands, controlled by Britain since the early 19th century, are of great geopolitical importance due to the Diego Garcia base, which has supported major military operations, including in Afghanistan and the Middle East.The deal also aims to resolve long-standing disputes over sovereignty, with Mauritius asserting its claim to the islands since independence. However, critics argue that the move could weaken the strategic positioning in the region, especially amid increasing global competition.
Political reactions and criticism intensified
The postponement of the deal sparked strong political reactions. Conservative Leader Kemi Badenoch welcomed the move, saying the agreement deserved to be consigned to the “ash heap of history” and accused Starmer of trying to “hand over British sovereign territory.”Likewise, UK reform leader Nigel Farage described the pause as “long overdue” and urged the government to prioritize resettlement rights for displaced Chagos residents.However, critics elsewhere said the handling of the deal had been inconsistent. Callum Miller, the Lib Dems’ foreign affairs spokesman, described the process as “completely chaotic” and warned that Trump’s changing position had exposed weaknesses in the UK-US partnership.On the other hand, many Chagossians opposed the deal, seeing it as a betrayal that failed to guarantee their right to return to the islands after being displaced decades ago.With no Chagos-related legislation expected in the King’s next speech, the future of the agreement remains uncertain, as the UK continues negotiations with both the US and Mauritius.
