On October 5, Mauritius Prime Minister Navin Ramgoolam made a statement on his Facebook page regarding his recent trip to the UK, specifically addressing the Chagos dispute. Ramgoolam claimed to have had a stern conversation with Jonathan Powell, the UK Prime Minister's national security adviser, on October 2. He stated that he clearly conveyed that Mauritius' sovereignty over the Chagos Islands is not negotiable and emphasized that time is of the essence. Ramgoolam also reaffirmed that international law is on Mauritius' side and demanded that the agreement signed must be ratified as planned.
According to Ramgoolam, he received assurance from Jonathan Powell that his concerns were heard, with Lord Charles Powell, Jonathan's brother and former adviser to Margaret Thatcher, serving as a witness to the conversation. However, the details of the discussion remain unclear, and it is uncertain whether Jonathan Powell promised to convey Ramgoolam's message to UK Prime Minister Andy Burnham. The Facebook post did not provide further insight into the conversation, leaving many questions unanswered.
A key question arising from Ramgoolam's statement is what specific legal action Mauritius plans to take against the UK. Will Mauritius pursue the UK government for not ratifying the treaty on the Chagos Islands, which was signed by Keir Starmer on May 22, 2025? The treaty, also known as the "Agreement," does not automatically bind the UK, according to the late Professor Ian Brownlie's international law treatise. Brownlie notes that signature alone does not establish consent to be bound, but it does obligate the signatory state to act in good faith.
Ramgoolam's government may consider pursuing the UK for not implementing the February 25, 2019, advisory decision by the International Court of Justice (ICJ). However, the ICJ's ruling was only advisory, and the UK was not legally obligated to comply. Another possibility is that Mauritius may seek a legal opinion on the matter, which could be costly. In the past, the Mauritian government has paid significant fees to law firms, including Withers LLP and Geoffrey Cox.
The Chagos dispute has been ongoing for decades, with Mauritius claiming sovereignty over the islands. The UK has maintained a significant presence in the region, and the issue remains a contentious one. Ramgoolam's statement suggests that Mauritius is willing to take a firm stance on the matter, but the path forward remains uncertain.
The UK's position on the Chagos Islands is complex, with the country having historically maintained a significant military presence in the region. While Keir Starmer signed the treaty on May 22, 2025, it remains unclear whether the UK government will ratify the agreement. If not, Mauritius may explore its options for seeking redress.
As the situation unfolds, one thing is clear: Mauritius is determined to assert its claim to the Chagos Islands. The question on everyone's mind is what specific steps the government will take next. With the UK's response still uncertain, the international community will be watching closely to see how this situation develops.
