British Prime Minister Keir Starmer says he has signed an agreement handing over sovereignty of the Chagos Islands to Mauritius.

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.

The Chagos Islands are in the middle of the Indian Ocean and home to a strategic military base on Diego Garcia.
