UK gives sovereignty of the Chagos Islands to Mauritius. The US base on Diego Garcia stays

The U.K. has agreed to hand sovereignty of the long-contested Chagos Islands, an archipelago of more than 60 islands in the Indian Ocean, to Mauritius, in a deal to secure the future of a strategically important U.K.-U.S. military base at Diego Garcia. The British government said Thursday the agreement is strongly supported by international partners including the U.S. As part of the deal, the U.K. will retain sovereignty of Diego Garcia for an initial period of 99 years. Britain's government said without the deal the secure operation of the military base would be under threat, with contested sovereignty and legal challenges.
