London (Washington Insider Megazine) January 30, 2026 – Chagos Islands exiles have offered to name one of the archipelago’s islands after U.S. President Donald Trump if he blocks the UK-Mauritius sovereignty agreement. Chagossian leader in exile Misley Mandarin urged Trump to veto the deal, describing it as essential to preserve British control and allow their return. The proposal follows Trump’s recent criticism of the arrangement as “an act of great stupidity,” despite prior U.S. endorsement, prompting renewed talks between London and Washington. UK officials maintain the treaty secures the Diego Garcia military base for generations while addressing international legal challenges.
The Chagos government in exile, led by Misley Mandarin, formally proposed renaming an island in honour of President Trump as a “gesture of thank you” for intervening against the UK’s planned handover of sovereignty to Mauritius. Mandarin, selected by UK-based Chagossians in late 2025 as their “first minister,” contacted Trump directly and expressed 100 per cent confidence that Washington would halt the process. He suggested the renaming could also boost American tourism to the remote Indian Ocean territory.
This development coincides with Trump’s 19 January Truth Social post condemning the deal, marking a reversal from earlier Trump administration support expressed by Secretary of State Marco Rubio. UK Prime Minister Sir Keir Starmer insisted on 28 January that Trump had initially backed the agreement “in very clear terms” following U.S. intelligence review.
Background to UK-Mauritius Chagos Islands Agreement
The UK agreed in May 2025 to transfer sovereignty of the Chagos Archipelago to Mauritius under a £4.5 billion treaty, leasing back Diego Garcia—the largest island and site of a joint UK-U.S. military base—for at least 99 years. The arrangement followed International Court of Justice rulings deeming the islands Mauritian territory, despite lacking jurisdiction over Commonwealth areas, and aimed to secure the base’s legal foundation amid challenges.
A UK government spokesperson stated the deal ensures “the operations of the joint US-UK base on Diego Garcia for generations, with robust provisions for keeping its unique capabilities intact and our adversaries out.” The treaty received public endorsement from the U.S., Australia, and other Five Eyes allies, plus India and Japan, at the time of signing.
Chagossians were forcibly removed from the islands in the 1960s and 1970s to facilitate the Diego Garcia base construction, with no permanent inhabitants permitted since except military personnel. Campaigners, including the exile government, oppose the handover, arguing they were not consulted and favour British protectorate status for return rights.
Misley Mandarin’s Direct Appeal to President Trump
Mandarin wrote to Trump last week, interpreting the president’s social media criticism as a response to his plea. In interviews, he called for an immediate veto, stating Trump “needs to veto it as soon as possible” to prevent the surrender. The proposed island naming echoes a 2019 precedent when Israel named a Golan Heights settlement Ramat Trump after U.S. recognition of its sovereignty.
Mandarin questioned Starmer’s emphasis on Mauritius’s autonomy, asking, “What about British overseas territory? What about British Chagossians?” He expressed delight at Trump’s stance, linking it to broader U.S. security interests in the Indo-Pacific.
The White House has not directly responded to Mandarin’s letter, though Trump tied the Chagos decision to his push for U.S. acquisition of Greenland, warning China and Russia had noted Britain’s “act of total weakness.”
Trump Administration’s Shifting Position on Deal
Trump met Starmer in February 2025, reportedly stating the arrangement would “work very well,” with Rubio later welcoming it post-interagency review as securing Diego Garcia’s “long-term, stable, and effective operation.” However, Trump’s 19 January post labelled it unjustified stupidity, prompting UK reconsideration of U.S. involvement.
On 28 January, Starmer reiterated Trump’s initial support during a flight to China, as White House officials and Republican senators met Chagossian campaigners opposing the treaty. Further meetings occurred on 29 January, with sources indicating the exile group offered to name the main island after Trump for vetoing the deal and enabling their return as a British protectorate.
UK ministers emphasise national security remains paramount, with the base under prior legal threat from court decisions.
UK Political Reactions to Trump’s Criticism
Reform UK leader Nigel Farage aligned with Trump on 20 January, stating, “Thank goodness Trump has vetoed the surrender of the Chagos Islands.” Conservative leader Kemi Badenoch called it “not just an act of stupidity, but of complete self-sabotage,” after meeting U.S. House Speaker Mike Johnson, who shared her view.
House of Lords amendments to disclose full handover costs were voted down by ministers on 29 January. A Chagossian referendum amendment was ruled out by Speaker Sir Lindsay Hoyle as imposing public revenue charges.
Downing Street maintains the deal’s international backing and base protections, rejecting compromise claims.
Strategic Importance of Diego Garcia Military Base
Diego Garcia hosts a vital UK-U.S. naval and air facility supporting Indo-Pacific operations, drawing Trump administration focus amid traditional European ties. The base’s capabilities are preserved under the treaty, with adversaries excluded via lease terms.
Human Rights Watch noted on 20 January that Trump’s attack overlooks Chagossians’ unresolved return rights, as Mauritius also bars habitation except for base staff. The archipelago’s uninhabited status persists post-evictions.
Ongoing Campaign Efforts by Chagos Exile Government
The UK-based Chagossian government in exile advocates retaining British sovereignty to facilitate returns. Mandarin’s leadership focuses on lobbying U.S. figures, with recent Capitol Hill and State Department engagements.
Opponents assert the deal undermines Chagossian interests without consultation, favouring protectorate status over Mauritian control. The naming offer aims to secure Trump’s intervention amid his Greenland rhetoric linking Arctic and Indian Ocean security.
Legal and International Context of Sovereignty Dispute
The treaty addresses ICJ opinions on Mauritian sovereignty, though non-binding on Commonwealth matters. Signed last May, ratification awaits final U.S. and allied alignment.
Reuters outlined key facts on 20 January, noting Trump’s call amid ongoing implementation. Sky News highlighted controversy over Diego Garcia’s formal transfer despite lease-back.
As of 30 January, the Telegraph reported exiles’ renewed naming pledge to derail Starmer’s agreement. UK-U.S. talks continue, with no formal veto confirmed.
