Ramgoolam and UK's Burnham Agree Chagos Roadmap at Commonwealth Summit
Mauritius PM Navin Ramgoolam met UK counterpart Andy Burnham at the Commonwealth Summit in Antigua, agreeing a plan to advance the Chagos deal before December 2026.
Mauritius Prime Minister Navin Ramgoolam wrapped up the 28th Commonwealth Heads of Government Meeting in Antigua and Barbuda with a one-on-one bilateral meeting focused on the long-running Chagos Islands dispute, sitting down with his British counterpart Andy Burnham to push the negotiations forward.
The two leaders agreed on a roadmap to make concrete progress on the issue before December 2026, signalling renewed momentum in talks that have stretched on for years. Mauritius has long maintained that the Chagos Archipelago, situated in the Indian Ocean, is part of its sovereign territory, a position backed by an advisory opinion from the International Court of Justice in 2019 and a United Nations General Assembly resolution in 2019.
The archipelago has been administered by the United Kingdom as the British Indian Ocean Territory since 1965, when it was detached from Mauritius before the island nation gained independence in 1968. The UK leases Diego Garcia, the largest atoll in the chain, to the United States as a major military base. That base is widely considered a strategic asset of significant geopolitical importance.
A draft agreement between Mauritius and the UK was announced in October 2024 under the previous British government, but the deal stalled amid political scrutiny on both sides. The transition to a new UK government, combined with continued concerns about the terms of the arrangement, meant negotiations required fresh impetus at the highest level.
Mauritius is reported to have opposed certain conditions or elements within the current framework during the discussions, though the full details of those objections were not disclosed in available reporting. The two governments appear to have used the margins of the Commonwealth Summit, a forum of 56 member states sharing historical ties to Britain, as an opportunity to reset the conversation directly between principals.
The Commonwealth summit in Antigua and Barbuda brought together heads of government from across Africa, the Caribbean, the Pacific and Asia, making it a natural setting for Mauritius to press its sovereignty claim at the international level while engaging the UK bilaterally.
What this means: For Mauritians, the December 2026 target date gives the negotiations a clearer timeline than has existed in recent years. If a final agreement is reached, it would formally recognise Mauritian sovereignty over the Chagos Islands while likely allowing continued operation of the Diego Garcia base under a lease arrangement. That outcome would be a historic milestone for a dispute that traces back to decisions made before Mauritius even became an independent country.

Frequently Asked Questions
What is the Chagos Islands dispute between Mauritius and the UK?β
The Chagos Islands, also known as the British Indian Ocean Territory, were separated from Mauritius by the UK in 1965, three years before Mauritius gained independence in 1968. Mauritius argues the detachment was unlawful and that the archipelago is part of its sovereign territory. In 2019, the International Court of Justice issued an advisory opinion supporting Mauritius, and the UN General Assembly called on the UK to end its administration of the islands. The UK and US operate a major military base at Diego Garcia, the largest island in the chain.
What was agreed at the Commonwealth Summit between Mauritius and the UK on Chagos?β
At the 28th Commonwealth Heads of Government Meeting held in Antigua and Barbuda, Mauritius Prime Minister Navin Ramgoolam and UK Prime Minister Andy Burnham agreed on a plan to advance the Chagos negotiations before December 2026. The specific terms were not publicly detailed, but the meeting signals a renewed commitment from both sides to reach a resolution within a defined timeframe.
How would a Chagos deal affect Mauritius?β
A finalised agreement would formally recognise Mauritian sovereignty over the Chagos Archipelago for the first time since 1965. It is widely expected to include a lease arrangement allowing the US and UK to continue operating the Diego Garcia military base. For Mauritius, the deal would represent a landmark diplomatic achievement and could come with financial terms, resettlement rights for displaced Chagossians, and strengthened international standing.
