The UK’s Chagos Islands pact with Mauritius may lead to the exile of certain islanders.

• Human Rights Watch warns that the UK government’s deal to hand over the Chagos Islands to Mauritius could “entrench” the exile of Chagossians from Diego Garcia, the largest island in the archipelago.

• The forcible displacement of the entire Chagossian indigenous people, mostly to Mauritius, for a U.S. military base on Diego Garcia is described as an “ongoing colonial crime against humanity.”

• The deal will see Britain pay £101 million annually for 99 years to lease the facility.

• Mauritius will be able to resettle Chagossian islanders to all over 50 islands, apart from Diego Garcia.

• The British government will establish a £40-million trust fund for the 10,000-strong Chagossian diaspora.
