The Chagos archipelago is a group of islands south of the Maldives that were a dependency of Mauritius until 1965. The US wanted a base in the Indian Ocean and identified the largest island, Diego Garcia, as ideal.

Both acts have been declared illegal and the Chagossians are on the verge of returning home. But will Mauritius’ claim for sovereignty undermine this? And what sinister forces are at work?
