The UK has announced it is giving up sovereignty of a remote but strategically important cluster of islands in the Indian Ocean after more than half a century.

The deal – reached after years of negotiations - will see the UK hand over the Chagos Islands to Mauritius in a historic move.

This includes the tropical atoll of Diego Garcia, used by the US government as a military base for its navy ships and long-range bomber aircraft.

The announcement, made in a joint statement by the UK and Mauritian Prime Ministers, ends decades of often fractious negotiations between the two countries.

The US-UK base will remain on Diego Garcia – a key factor enabling the deal to go forward at a time of growing geopolitical rivalries in the region between Western countries, India, and China. //

Half a century or more after the UK relinquished control over almost all its vast global empire, it has finally agreed to hand over one of the very last pieces. It has done so reluctantly, perhaps, but also peacefully and legally.

The remaining British overseas territories are: Anguilla, Bermuda, British Antarctic Territory, British Virgin Islands, Cayman Islands, Falkland Islands, Gibraltar, Montserrat, Pitcairn, Saint Helena, Ascension and Tristan da Cunha, South Georgia and the South Sandwich Islands, Turks and Caicos Islands. There are also two sovereign base areas on Cyprus under British jurisdiction.
