LONDON, UK: The United Kingdom on Saturday, April 11, confirmed it will not proceed with its previously announced plan to transfer sovereignty of the Chagos Islands to Mauritius, marking a significant shift in policy.

The 2024 agreement, which aimed to resolve longstanding legal disputes over the Indian Ocean territory, has been halted following changes in strategic and diplomatic considerations.



British officials indicated that the decision reflects current security priorities, particularly concerning the continued operation of the joint UK-US military base on Diego Garcia.

The United States plays a central role in operating the facility, which is considered a key strategic asset in the region.



The announcement follows months of public criticism of the proposed transfer by President Donald J Trump, who had questioned the implications of the deal for military readiness and regional security.

Diego Garcia base gains importance amid Iran-linked operations

The Diego Garcia base has taken on heightened importance amid recent military operations linked to the conflict with Iran.

US defense planning has relied on the base’s location and capabilities, including its role in supporting long-range bomber missions and logistical operations.

Trump had previously emphasized the importance of maintaining uninterrupted access to the facility, particularly during ongoing military engagements.

While the US State Department had earlier signaled openness to the sovereignty transfer, the administration’s position shifted as operational demands increased.

UK officials acknowledged that continued US cooperation is essential to the base’s functioning, and that any change in sovereignty would require alignment with joint defense requirements.

Keir Starmer flags economic impact of global tensions

The policy reversal has also added strain to diplomatic relations between Washington and London. Prime Minister Keir Starmer addressed the broader impact of global tensions on the UK economy, including rising energy costs and market instability linked to the conflict.

In recent remarks, Starmer referenced the challenges posed by shifting international dynamics, drawing comparisons to the economic disruptions seen in previous geopolitical crises.

His comments reflected domestic pressure as the UK manages the economic effects of ongoing global developments.

Officials in London have not directly linked the decision on the Chagos Islands to specific statements by US leadership, but acknowledged that coordination with allies remains a key factor.

US-UK tensions rise over military cooperation

Tensions between the two governments have been further highlighted by public exchanges over military cooperation. Earlier in the conflict, the UK briefly reviewed the use of certain bases for US operations before reaffirming its support.



During that period, Trump publicly questioned the pace of the UK’s response, referencing historical leadership comparisons. UK officials subsequently confirmed continued access to facilities, including Diego Garcia and RAF Fairford, for US operations.

Despite these exchanges, both governments have maintained ongoing coordination on defense matters.

Operational security of Diego Garcia takes precedence over treaty

In its official statement, the UK government said that ensuring the long-term operational security of Diego Garcia remains its primary concern.

Officials noted that while the proposed agreement with Mauritius was intended to provide a durable legal framework, current conditions require maintaining existing arrangements.

The government added that discussions with Mauritius will continue, though no revised timeline for sovereignty negotiations has been provided.

For now, the Chagos Islands will remain under British administration, with Diego Garcia continuing to function as a key military hub supporting joint operations.
