On Thursday, the United Kingdom signed a controversial £101 million annual agreement with Mauritius over the Chagos Islands, an archipelago in the Indian Ocean that houses a major UK-US military base on Diego Garcia. This agreement has once again thrown the spotlight on Britain’s colonial past and the disputed sovereignty over the islands. The new lease, which will last for 99 years, allows Britain to maintain military control over Diego Garcia while technically handing over jurisdiction of the Chagos Islands to Mauritius.
“The strategic location of this base is of the utmost significance to Britain,” said UK Prime Minister Keir Starmer, referring to ongoing international security operations across the Red Sea and Indo-Pacific.

Critics of the deal, particularly opposition leaders and human rights advocates have called the agreement both morally wrong and financially irresponsible. They argue that the UK is essentially paying to maintain control of a territory that the United Nations and the International Court of Justice (ICJ) have repeatedly said must be returned to Mauritius.
In 2019, the ICJ declared that the UK’s continued occupation of the islands was illegal under international law. The UN General Assembly followed with a vote urging Britain to hand over the territory. Despite this, Britain has now committed to a £3.4 billion long-term payment arrangement with its former colony.
Conservative MP Priti Patel slammed the decision as “bad for our defence and security interests, bad for British taxpayers and bad for British Chagossians.”

The deal’s announcement was briefly stalled when the UK High Court granted an interim order to a British citizen born in the Chagos Islands. That legal setback, however, did not stop the UK government from signing what it calls a strategic necessity.
“This individual and his co-conspirators preyed on the vulnerability of the elderly and recently widowed to defraud them of their hard-earned life savings,” said ICE Homeland Security Investigations Special Agent Chad Plantz during a related announcement about international cooperation.
The UK insists that keeping the Diego Garcia base under British control is essential for long-term global security. Still, critics argue this is just another way for Britain to justify clinging to colonial territory at the expense of Chagossians who were forced out decades ago.
By repeatedly defying international legal orders and now paying a massive sum to legitimize its hold, Britain has exposed its willingness to trade moral responsibility for military strategy. This has reignited debates about whether the UK is ready to confront its colonial past or simply monetize it.
