The UK’s proposal to transfer sovereignty of the Chagos Islands to Mauritius has sparked heated debate, with critics warning of possible security risks to the joint UK-US military base on Diego Garcia. The deal, championed by Labour leader Sir Keir Starmer, has faced backlash from opposition figures and international observers alike.

Mauritius Prime Minister Dr. Navin Ramgoolam rejected the initial agreement, calling it “not good enough” and demanding a renegotiation.

Fresh concerns have emerged about whether the deal adequately safeguards against foreign powers, particularly China, establishing military installations on other islands in the Indian Ocean archipelago.

Shadow Defence Minister Mark Francois voiced apprehensions in parliament, questioning whether Mauritius could allow third-party military presence on Chagos Islands not included in the agreement. These fears stem from China’s growing geopolitical ambitions and its potential to exploit the sovereignty shift to position itself closer to Diego Garcia, a critical hub for regional security.

In a written response, Defence Minister Luke Pollard assured that robust measures were in place to protect Diego Garcia.

“Our primary goal throughout negotiations was to protect the joint UK-US military base on Diego Garcia, which plays a crucial role in regional and international security. The operation of the base will continue unchanged with strong protections from malign influence.”

However, critics like Francois remain skeptical, stating: “Yet more Chagos chaos from this government … The protections against a third country, such as China, putting installations elsewhere in the archipelago may be weaker than first mooted.”

The deal’s rejection by Mauritius has further complicated the situation. Ramgoolam argued that the proposed terms would not deliver sufficient benefits to his nation. The Mauritian government’s stance has reignited calls for a renegotiation to address economic and sovereignty concerns.

At the heart of the debate lies the Treaty of Pelindaba, which prohibits nuclear weapons in Mauritius’ territory. This has raised questions about whether Britain and the US could maintain the operational flexibility of Diego Garcia, given its strategic role in nuclear deterrence.

The outgoing Biden administration has supported the agreement, but former US President Donald Trump and his team have signaled strong opposition. Nigel Farage, addressing parliament, suggested the deal could set a dangerous precedent akin to the UK’s failed commitment to Hong Kong.

“There is very deep disquiet among senior members of the incoming administration,” Farage said, referencing his conversations at Trump’s Mar-a-Lago resort. “They can’t understand why we would surrender sovereignty of these islands on an advisory judgment from a pretty obscure court.”

Labour Defends the Deal

Despite mounting opposition, Labour remains steadfast in its commitment to finalize the handover. Responding to an urgent question from Tory Shadow Foreign Secretary Dame Priti Patel, Foreign Office Minister Stephen Doughty insisted the deal aligns with the UK’s national security interests.“Let’s get back to the actual facts,” Doughty urged.

“The Prime Minister has confirmed himself in Mauritius to his assembly that he is willing to conclude this deal with the United Kingdom. Those are the facts, and we will protect our national security and our interests.”

Doughty dismissed fears of a breakdown in UK-US relations, expressing confidence that once Trump’s team reviewed the details, they would support the agreement.

Meanwhile, Farage suggested that the terms of the deal be put to a referendum among exiled Chagossians, many of whom have long campaigned for the right to return to their homeland.

“The voices of the Chagossians must be heard,” he asserted. “Their input is vital in ensuring any agreement reflects the will of those most directly affected.”

The ongoing saga underscores the delicate balance between strategic military considerations, international relations, and the rights of displaced communities. As debates rage on, the future of the Chagos Islands remains uncertain, with both domestic and global implications hanging in the balance.
