It is unclear what the announcement will mean for them.The UK will provide a package of financial support to Mauritius, including annual payments and infrastructure investment.

Mauritius will also be able to begin a programme of resettlement on the Chagos Islands, but not on Diego Garcia.There, the UK will ensure operation of the military base for "an initial period" of 99 years.US President Joe Biden welcomed the "historic agreement", saying it was a "clear demonstration that through diplomacy and partnership, countries can overcome long-standing historical challenges to reach peaceful and mutually beneficial outcomes".

He said it secured the future of a key military base which "plays a vital role in national, regional, and global security."The Chagos islanders themselves – some in Mauritius and the Seychelles, but others living in Crawley in Sussex – do not speak with one voice on the fate of their homeland.

Some are determined to return to live on the isolated islands, some are more focused on their rights and status in the UK, while others argue that the archipelago’s status should not be resolved by outsiders.

Isabelle Charlot, speaking on BBC Radio 4's World At One programme, said the deal brought back hopes her family could return to her father's island "roots".Interestingly, Sir Keir took issue with the long-standing view of many that immigration helps drive or at least prop up economic growth.

The other context here is the insurgency of Reform UK.Nigel Farage argues, as he has for years and years, that politicians have been far too slow to get how much immigration matters to so many people.
