Mauritius is contemplating legal action against the United Kingdom concerning the ongoing delays in ratifying an agreement over the Chagos Archipelago. The announcement was made by the country’s former prime minister, Navin Ramgoolam, who indicated that the government is currently consulting with legal firms to explore available options.
The Chagos Archipelago, which includes the strategically significant island of Diego Garcia, was administered by Britain alongside Mauritius until 1965. Following Mauritius’ independence in 1968, the sovereignty over these islands has been a contentious issue. An agreement signed in May 2025 stipulates that the UK will transfer sovereignty of the Chagos Islands to Mauritius while leasing Diego Garcia back for an initial period of 99 years. This arrangement is critical for the continued operation of the joint US-UK military base located there, which is seen as a vital asset for military operations in the Indian Ocean and the Middle East.
The lease payments for Diego Garcia are projected to total approximately $3.9 billion over the duration of the lease. Despite this significant financial promise, the ratification process has stalled in the British Parliament, drawing scrutiny from various political figures, including US President Donald Trump, who described the UK’s decision as an act of “great stupidity” and “total weakness.”
In a recent interview with Le Défi Quotidien, Ramgoolam expressed concerns about the impact of the delay on Mauritius’ national budget, which is facing a shortfall of about 10 billion Mauritian rupees (approximately $211 million). He acknowledged that the budget for the fiscal year 2026–27 would be particularly challenging.
The situation has also led to diplomatic tensions with the Maldives. On February 27, 2024, Mauritius suspended diplomatic relations after the Maldives refused to recognize Mauritian sovereignty over the Chagos Archipelago. The Mauritian Foreign Ministry stated that the Maldives “no longer recognizes the sovereignty of the Republic of Mauritius over the Chagos Archipelago, its territorial integrity, and is now objecting to the Agreement between Mauritius and the United Kingdom.”
As Mauritius navigates these complex geopolitical waters, the potential for legal action against the UK marks a significant chapter in the long-standing dispute over the Chagos Islands, highlighting the intersection of international law, diplomatic relations, and national interests.
