Volkswacht Bodensee - UK hands Indian Ocean islands to Mauritius but keeps key US military base

The British government has been under pressure for decades to hand over the islands but has resisted because of the Diego Garcia base's key role for US operations in the Indian Ocean and Gulf.

"For the first time in more than 50 years, the status of the base will be undisputed and legally secure," the UK foreign ministry said. A joint British-Mauritius statement said the base would remain open on an "initial" 99-year lease.

Biden hailed the continuation of the base on Diego Garcia -- the largest island in the chain -- which was notably used during the wars in Afghanistan and Iraq. The base is used by US long range bombers as well as US ships.

"I applaud the historic agreement and conclusion of the negotiations," Biden said in a White House statement, adding that the site "plays a vital role in national, regional, and global security".

Mauritius Foreign Minister Maneesh Gobin called the announcement "a day to remember" and a "seminal moment" in his country's relationship with former colonial power Britain.

British Prime Minister Keir Starmer said he spoke to his Mauritian counterpart Pravind Jugnauth and both hailed the agreement, according to Downing Street.

- Turnaround -

The deal comes after nearly two years of negotiations and marks a significant turnaround after decades of British dismissals of Mauritian sovereignty claims.

At the start of talks in 2023, the two sides agreed that the Diego Garcia military base would continue to operate whatever the outcome.

In 2016, the UK extended the US lease of the military base until 2036.

The joint British-Mauritius statement said the two would work on a treaty finalising the accord that would ensure Diego Garcia's operation "well into the next century".

The treaty could also pave the way for the return of Chagos islanders, who were expelled by the UK in the 1970s as the military base was developed.

But with no permanent population -- and Diego Garcia the only habitable island and remaining off-limits as part of the deal -- resettlement looks unlikely.

Britain decided in 1965 to separate the Chagos islands from Mauritius and set up a military base there, which it leased to the United States.

In doing so, it evicted thousands of Chagos islanders who have since mounted a series of legal claims for compensation in the British courts.

The joint statement claims the agreement will "address wrongs of the past" and "support the welfare of the Chagossians", who were forced to live in exile, including in the UK.

But Chagossian Voices, representing islanders around the world, said they were excluded from the talks and only learned of the deal from the media.

"The views of Chagossians, the indigenous inhabitants of the islands, have been consistently and deliberately ignored and we demand full inclusion in the drafting of the treaty," they added.

- Mounting pressure -

Mauritius has claimed the archipelago -- renamed British Indian Ocean Territory -- since its independence in 1968 and garnered increasing international support.

In 2019 the International Court of Justice advised Britain to hand over the remote islands. During the hearings, the UK apologised for the "shameful" eviction of islanders, but ignored the ICJ ruling at the time.

The same year, the UN General Assembly also voted a resolution calling on Britain to "withdraw its colonial administration".

Without the agreement, "the long-term, secure operation" of the military base would be under threat, Britain's foreign ministry said, including through legal challenges posed by international courts.

"Today's agreement secures this vital military base for the future," Foreign Secretary David Lammy said, adding that the deal would also shut down the potential use of the islands being used as a "dangerous illegal migration route to the UK".

In addition, the UK announced a "package of financial support" to Mauritius including an annual payment and an infrastructure partnership.

Claiming to resolve "all outstanding issues between the United Kingdom and Mauritius" with the agreement, the countries will also cooperate on environmental and irregular migration, the joint statement said.
