The United Kingdom has permanently paused its transfer of the Chagos Islands to Mauritius after President Trump withdrew American cooperation for the 2024 agreement. The British government announced Saturday that it is abandoning the deal entirely, stating it cannot proceed with the transfer without U.S. support.
The agreement, which would have transferred sovereignty of the islands to Mauritius while allowing continued use of the Diego Garcia military base, stemmed from a decades-long legal battle addressing Britain's colonial past. The U.K. and U.S. have shared the strategic base on Diego Garcia, the largest island in the Chagos archipelago, since the 1970s.
The British government said ensuring the Diego Garcia base's long-term operational security remains its priority. "We are continuing to engage with the U.S. and Mauritius," the statement said.
What the Left Is Saying
Progressive Democrats and international law advocates have expressed frustration with the reversal. Prime Minister Keir Starmer pushed back against Trump's criticism of the original deal in January, noting the president's previous words of "welcome and support" during their White House meeting.
Starmer has also criticized Trump's handling of the U.S.-Israeli conflict with Iran, initially pausing the U.K.'s approval for American forces to use British bases during "Operation Epic Fury." After reversing his position following Trump's attacks, Starmer drew parallels between Trump and Russian President Vladimir Putin over energy prices.
"I'm fed up with the fact that families across the country see their bills go up and down on energy, businesses' bills go up and down on energy, because of the actions of Putin or Trump across the world," Starmer told ITV News.
Progressive critics argue that abandoning the transfer undermines Britain's efforts to address its colonial legacy and cede territory that has been under U.K. control since the 1960s.
What the Right Is Saying
Republicans and Trump supporters have celebrated the decision to halt the transfer. Trump called the original deal a "great act of stupidity" in January and posted on Truth Social in February urging the British government: "DO NOT GIVE AWAY DIEGO GARCIA!"
Trump defended his criticism of Starmer after the U.K. prime minister initially refused to allow U.S. forces to use British bases for operations against Iran. Trump called Starmer "not Winston Churchill" and said he was surprised by the response given the strong U.S.-U.K. relationship.
"They were really pretty much our first ally. ... They didn't want us to use the island — the so-called island — which for some reason they gave up rights to it," Trump told The Hill last month.
Conservatives argue the Diego Garcia base is critical to American military operations in the Indo-Pacific region and that transferring sovereignty to Mauritius would have compromised U.S. strategic interests. They praise Trump for prioritizing American security over historical reconciliation efforts.
What the Numbers Show
The Chagos Islands have been under British control since the 1960s, when the U.K. expelled approximately 2,000 Chagossian residents to make way for the military base. The original 2024 agreement was intended to resolve a long-standing territorial dispute at the United Nations.
The Diego Garcia base hosts approximately 1,500 U.S. military personnel and contractors. The facility is considered strategically vital for American power projection in the Indian Ocean region.
The U.S.-Iran conflict that began Feb. 28 has contributed to higher prices on trade goods and oil exports in the United Kingdom, according to economic data cited in Starmer's public statements.
The Bottom Line
The reversal of the Chagos Islands transfer highlights ongoing tensions between the U.S. and U.K. over strategic priorities versus post-colonial reconciliation. The British government has prioritized maintaining the Diego Garcia base's operational security, which it called "the entire reason for the deal." The U.K. will continue engaging with both the U.S. and Mauritius, but the path forward for any revised agreement remains unclear.
The episode illustrates the broader challenge of balancing historical justice claims with contemporary security interests, particularly in U.S. strategic partnerships in the Indo-Pacific.
