At precisely the moment Britain is contemplating one of the most consequential territorial decisions in decades, alarming signals are emerging from Mauritius, the very country to which sovereignty of the Chagos Islands may be ceded.
Paul Bérenger, until recently Mauritius’s Deputy Prime Minister and one of its most senior political figures, has resigned citing corruption as a driving factor. His claims are not vague insinuations but detailed allegations: a minister approached with a bribe by intermediaries linked to the Prime Minister’s Office, individuals allegedly removed and then quietly reinstated, and a purported recorded conversation involving discussions of money at the heart of government.
He further points to what he calls the “Mamy Ravatomanga affair”, alleging that “many millions” are at stake and that evidence, reportedly a recording, was dismissed as artificial intelligence. None of these claims have yet been independently verified, and the Mauritian government has not publicly responded. But that is precisely the point: when allegations of this seriousness surface at the highest levels of government, the burden is on the state to demonstrate transparency and accountability. Silence only deepens concern.
This is not a minor domestic dispute. It lands squarely in the middle of sensitive negotiations with the United Kingdom over the future of the Chagos Archipelago, a strategically vital territory that hosts the UK-US military base on Diego Garcia. The stakes for Britain are not abstract. They are military, geopolitical, and long-term.
The question is simple and unavoidable: can the UK responsibly transfer sovereignty of such a critical asset to a government facing credible allegations of corruption at its core?
Concerns do not stop at internal governance. There is growing unease about Mauritius’s broader strategic posture, including reported discussions and speculation around deals involving access to seabed resources, rare minerals, expanded fishing rights, and commercial exploitation of surrounding waters. In an era of intensifying global competition, particularly involving China’s expanding footprint across the Indian Ocean, any ambiguity about how such rights might be allocated should give policymakers pause.
The Chagos Islands are not just another territorial negotiation. They sit at the crossroads of global security architecture. Diego Garcia remains indispensable to Western defence capabilities, from counterterrorism operations to Indo-Pacific stability. To treat its future as a routine diplomatic concession would be a profound miscalculation.
Supporters of a deal argue that Britain must resolve longstanding legal disputes and align with international advice. But legal considerations cannot be divorced from present-day realities. Sovereignty is not an abstract moral token, it carries with it control over territory, resources, and strategic leverage.
If there are unresolved questions about corruption, governance, and external influence in Mauritius, then proceeding regardless would not be principled, it would be reckless.
At a minimum, any agreement must be contingent on demonstrable standards: transparency, institutional integrity, and binding guarantees over security and resource governance. Even then, scepticism would remain justified.
Britain is not merely negotiating a handover. It is making a generational decision about national security and geopolitical stability. To proceed in the face of such uncertainty would be to ignore the most basic duty of government: to act in the long-term interests of its people and its allies.
Until all doubts are credibly resolved, and until the Chagossian people themselves are granted genuine self-determination, there is only one responsible course.
Britain must hold its ground.
The Chagos Islands should not be handed over, and their future must remain under British sovereignty.
