Nigel Farage Issues Stark Chagos Warning to Andy Burnham Ahead of Donald Trump Meeting: ‘Can’t Go Ahead!’

Nigel Farage has issued a warning to Prime Minister Andy Burnham over the future of the Chagos Islands ahead of Burnham’s first face-to-face meeting with US President Donald Trump, arguing that Britain should not proceed with arrangements that could increase Chinese influence around the strategically important Diego Garcia military base.

Farage’s intervention comes at a particularly sensitive moment for the British government. Burnham is due to meet Trump in New York during the United Nations General Assembly, while the future of the Chagos Archipelago remains a disputed issue between Britain, Mauritius and the United States.

Speaking to GB News, the Reform UK leader said Burnham should make clear to Trump that Britain would not allow arrangements surrounding the Chagos Islands to undermine the strategic position of Diego Garcia.

Farage’s comments represent a political challenge to Burnham, but they also reflect a wider international problem surrounding the future of the Indian Ocean territory. The British government has already signed an agreement with Mauritius concerning sovereignty over the Chagos Archipelago, while the implementation of that agreement has faced opposition from Washington.

Farage’s warning to Burnham

Farage was asked what advice he would give Burnham before the Prime Minister’s meeting with Trump.

The Reform leader said Burnham should begin the conversation by making clear that Britain would not allow the Chagos Islands to become an avenue for increased Chinese influence.

He specifically highlighted two issues: the future of the Diego Garcia base and the position of the Chagossian people.

Farage argued that Burnham needed to make clear that the proposed arrangements could not simply proceed if they created a strategic problem for Britain and the United States. He also urged the Prime Minister to adopt a tougher position when discussing the Falkland Islands and other areas of disagreement with Washington.

His remarks were particularly significant because Trump has already criticised the Chagos agreement.

The US president has described the deal as a “big mistake”, while the legislation required to implement the agreement has not yet completed its passage through the British Parliament.

That means Burnham enters his meeting with Trump at a time when the two governments have a shared interest in maintaining the Diego Garcia base but do not necessarily agree about how the wider sovereignty question should be resolved.

Why Diego Garcia matters

Diego Garcia is the largest island in the Chagos Archipelago and hosts a strategically important UK-US military installation.

The base has been used for military operations, communications and other strategic purposes and is regarded by Britain and the United States as an important element of their defence relationship.

The original UK-Mauritius agreement was designed to separate the sovereignty question from the continued operation of the military base.

Under the treaty published by the British government, Mauritius would have sovereignty over the Chagos Archipelago, including Diego Garcia, while Britain would retain arrangements allowing the continued operation of the military facility for an initial period of 99 years.

The British government has repeatedly argued that the agreement protects the long-term operation of Diego Garcia.

A 2025 statement from Defence Secretary John Healey said the treaty was intended to guarantee continued UK control of the base for the next 99 years and beyond.

However, the political situation changed significantly after Trump returned to the White House.

Washington has raised concerns about the strategic implications of transferring sovereignty to Mauritius, particularly because of the broader competition between the United States and China in the Indian Ocean.

That concern has become one of the central obstacles to implementing the agreement.

Burnham attempts to find a compromise

Burnham has not abandoned the existing agreement.

Instead, he has indicated that his government wants to find a solution acceptable to both Mauritius and the United States.

On September 21, Burnham spoke by telephone with Mauritian Prime Minister Navin Ramgoolam. According to Downing Street, Burnham stressed his commitment to working with Mauritius and the United States to secure the continued operation of Diego Garcia and protect British national security.

The two leaders also agreed that their foreign ministers should meet during the UN General Assembly in New York.

That development is important because it suggests that Burnham is attempting to manage the dispute diplomatically rather than simply choosing between the Mauritian agreement and the American objections.

Reuters reported that Britain has signed the treaty with Mauritius, but the legislation needed to put the agreement into effect has not completed its parliamentary passage.

This leaves room for further negotiations.

Trump meeting adds pressure

Burnham’s meeting with Trump is therefore taking place against a complicated diplomatic background.

The two leaders have already spoken by telephone, but the New York meeting will be their first face-to-face encounter.

Their relationship has attracted considerable attention because the governments have disagreed over several international issues.

The Chagos Islands are one of them.

Other areas of potential discussion include defence, Iran, Ukraine, the Falkland Islands and Britain’s wider relationship with the United States. The Times reported that Burnham’s priority is to establish a workable relationship with Trump despite differences between London and Washington.

The Chagos dispute could therefore become an important test of the Prime Minister’s diplomatic approach.

For Farage, the issue is straightforward: Britain should not make an arrangement that could allow an important military location to become vulnerable to foreign influence.

The Reform leader has previously criticised the Chagos agreement and has argued that Britain should reconsider the deal.

His latest comments put that position directly into the context of Burnham’s meeting with the American president.

The Chinese influence question

China’s role is at the heart of many of the concerns surrounding the Chagos dispute.

Mauritius has maintained diplomatic and economic relations with China, as have many countries across the Indian Ocean region. For Washington, the possibility of increased Chinese influence around a strategically important military facility is therefore a significant consideration.

However, the British government has argued that the treaty contains safeguards intended to protect the operation of Diego Garcia.

The 2025 Defence Ministry statement said the agreement included restrictions designed to protect the base and its surrounding security environment. The government also emphasised that Britain would retain operational control of the facility.

The disagreement, therefore, is not simply about whether Diego Garcia will continue operating.

There is broad recognition of the importance of the base.

The more difficult question is how its long-term security can be guaranteed while sovereignty over the wider archipelago changes.

The Chagossian dimension

The dispute also involves the Chagossian people, whose families were removed from the islands decades ago.

The UK-Mauritius agreement includes provisions concerning the welfare of Chagossians and allows Mauritius to establish a programme for resettlement on islands other than Diego Garcia.

This humanitarian and historical dimension makes the dispute more complicated than a conventional military or territorial disagreement.

Farage’s warning concentrates heavily on security and sovereignty, while supporters of the agreement have emphasised international law, the historical treatment of Chagossians and the need to resolve the long-running sovereignty dispute.

Consequently, any decision by Burnham will have consequences beyond Britain’s relationship with Trump.

A difficult balancing act

Burnham now faces the task of balancing several interests at once.

Mauritius wants the sovereignty agreement implemented. The United States wants assurances about the security of Diego Garcia. Britain wants to maintain its military relationship with Washington while protecting its own strategic interests. Meanwhile, the Chagossian issue remains an important part of the political and legal background.

Farage’s intervention adds another layer of domestic political pressure.

His argument is that Burnham should use the meeting with Trump to make clear that Britain will not permit the Chagos settlement to create a strategic opening for China.

Burnham, however, has signalled that he wants to work with both Mauritius and the United States to find a resolution.

That difference illustrates the broader political divide over the issue.

For Farage, the priority is preventing any arrangement that could compromise Britain’s strategic position. For the government, the challenge is finding a framework that preserves the military base while dealing with the sovereignty dispute and Britain’s commitments to Mauritius.

What happens next?

The immediate focus will be Burnham’s meeting with Trump in New York and the diplomatic discussions surrounding the UN General Assembly.

The Prime Minister is unlikely to be able to settle the entire Chagos dispute in a single meeting.

The British Parliament must still consider the legislation required to implement the treaty, while London, Port Louis and Washington continue discussions over the future of Diego Garcia.

Farage’s warning nevertheless ensures that the issue will remain politically prominent.

His demand that the proposed arrangement “can’t go ahead” if it risks unacceptable foreign influence represents his political position, rather than a settled fact about the treaty’s consequences.

The central question for Burnham is therefore whether he can reassure Trump that Diego Garcia’s long-term security will be protected while maintaining Britain’s agreement with Mauritius.

With the strategic importance of the base widely recognised by both Britain and the United States, the outcome of those negotiations could have lasting implications for Britain’s defence policy, its relationship with Washington and the future of the Chagos Archipelago.
