UK Government Puts Chagos Islands Sovereignty Deal in 'Deep Freeze'
The United Kingdom has been compelled to shelve its agreement to transfer sovereignty of the Chagos Islands to Mauritius due to significant opposition from the United States, according to former top civil servant Lord Simon McDonald. The former Foreign Office permanent secretary stated that the Government had "no choice" but to place the plan in what he described as the "deep freeze" as it contends with an "openly hostile" US President.
Legislative Timeline Expires Amid Political Pressure
A Bill to cede sovereignty of the Indian Ocean archipelago is now unlikely to appear in the King's Speech, which outlines the legislative agenda for the upcoming parliamentary session. This development follows former President Donald Trump's public condemnation of the plan, which he labeled "an act of great stupidity." Officials confirm that the UK has yet to receive formal exchange of notes from Washington—a technical but legally essential step for enacting the treaty.
While the plan has not been entirely abandoned, the parliamentary timeline has effectively expired. Legislation cannot be passed before Parliament dissolves in the coming weeks, with a Government source characterizing the situation as "deeply frustrating." Lord McDonald, who served as the top mandarin at the Foreign Office from 2015 to 2020, defended the Government's position during a BBC Radio 4 interview.
International Law Versus Strategic Relationships
"The Government had no other choice," Lord McDonald explained. "The UK had two objectives: one was to comply with international law, the other was to reinforce the relationship with the United States. When the President of the United States is openly hostile, the Government has to rethink, so this agreement, this treaty will go into the deep freeze for the time being."
When questioned about whether alternative decisions could have facilitated the plan's realization, Lord McDonald emphasized that ministers were obligated to follow the International Court of Justice's 2019 advisory opinion, which recommended transferring the archipelago to Mauritius. He noted a growing trend of disregarding international law, led by the United States, and highlighted the UK's traditional commitment to upholding these legal standards.
Strategic Military Base at the Heart of the Dispute
Under the proposed deal, the UK would lease back the British-US military base on Diego Garcia for 99 years. However, ratification has stalled following Mr. Trump's public criticism. The Chagossian population was forcibly removed from the territory by 1973 to accommodate the military base, which remains a critical strategic asset for both nations.
Although the US initially agreed to the arrangement, Mr. Trump later denounced it as a "big mistake" amid deteriorating relations with Prime Minister Sir Keir Starmer over conflicting views on Greenland and the Middle East war. A Government source reiterated that securing the long-term operational future of Diego Garcia is the primary objective of the agreement.
Political Reactions and Future Implications
Conservative leader Kemi Badenoch declared that the agreement should find its "rightful place—on the ash heap of history," criticizing the Prime Minister for pursuing what she described as a misguided effort to surrender British sovereign territory. Meanwhile, the Liberal Democrats condemned the handling of the deal as "totally shambolic" across successive governments.
Liberal Democrat foreign affairs spokesman Calum Miller added: "Trump's fickle approach shows just how unreliable he is. We had a strong, stable, and effective military partnership with the US. Trump has gravely endangered that. Any deal must provide clarity on the future military partnership with the US and address Chagossian rights and Parliamentary scrutiny of the sums involved."
The Government remains committed to protecting Diego Garcia's operational capabilities, acknowledging ongoing threats, including potential legal challenges. Officials continue to engage with US administration and Mauritian counterparts to seek a solution that safeguards the base's future while addressing international legal obligations.
