The Chagos Islands are home to Diego Garcia, one of world's most secretive places and home to an important U.S. military base.

The governments of Britain and Mauritius have reached a final deal to settle the future of the Chagos Islands but have been barred from signing it by a British judge.

Britain signed a multi-billion dollar deal on the future of the Chagos Islands with Mauritius after a last-gasp injunction was overturned, securing itself a lease for the U.S.-UK Diego Garcia air base for the next century.
