This agreement, which would see the UK cede sovereignty over the islands to Mauritius while retaining a lease on the strategic US military base at Diego Garcia, has faced recent complications.

Deal for Chagos Islands Faces New Doubts

A prior agreement to transfer sovereignty of the Chagos Islands to Mauritius, while keeping the key UK-US military base on Diego Garcia operational under a lease, has encountered fresh obstacles. This deal, struck by the UK with the previous Mauritian government, has been re-evaluated by the new administration in Mauritius. Prime Minister Navin Ramgoolam has indicated that the draft deal did not sufficiently benefit his country, leading to renewed negotiations for revised terms and potentially increased financial contributions.

  • The UK had agreed to cede sovereignty of the Chagos Islands, also known as the British Indian Ocean Territory.

  • A lease agreement was to be maintained for the significant UK-US military base on Diego Garcia.

  • The new Mauritian Prime Minister, Navin Ramgoolam, has stated the initial deal was not beneficial enough.

  • This has prompted the recommencement of negotiations for a new, possibly more lucrative, arrangement.

Shifting US Political Landscape and Chagos

The Chagos Islands deal has become a point of contention within the US political sphere, particularly with the incoming Trump administration. Initially, Britain's top diplomat, David Lammy, expressed confidence that Donald Trump would support the agreement, even in the face of opposition from US Republicans. However, Marco Rubio, nominated as Trump's Secretary of State, publicly voiced concerns about the deal during his time as a US senator. He sought reassurances from David Lammy that the agreement would not negatively impact US security interests, given the presence of the American base. It remains unclear if these concerns have been fully addressed.

  • David Lammy had previously predicted Donald Trump's approval of the Chagos Islands deal.

  • Marco Rubio, prior to taking office as Secretary of State, expressed public criticism of the deal.

  • Rubio reportedly sought assurances from Lammy regarding US security interests at Diego Garcia.

  • The deal was not a subject of discussion during Keir Starmer's initial call with Donald Trump.

Geopolitical Factors Influencing the Deal

Recent reports indicate that Donald Trump's previous backing for the Chagos Islands agreement may have been withdrawn due to Britain's refusal to grant the US permission to utilize UK bases, specifically RAF Fairford, for potential military actions against Iran. The US president is reportedly considering further military action against Iran, a situation exacerbated by the movement of an American warship into the region and the lack of progress on Iran's nuclear program.
