evidence: The United Kingdom announced on Thursday that agreement has been reached to hand over the Chagos Islands to Mauritius, ending decades of dispute and negotiation over Britain’s last African colony. [...] Before granting independence to Mauritius in 1968, Britain was found to have unlawfully separated it to form a new colony on the Chagos archipelago named the British Indian Ocean Territory (BIOT). [...] The campaign challenging British ownership of the Chagos archipelago included the Mauritian ambassador to the UN, Jagdish Koonjul, raising his country’s flag above the atoll of Peros Banhos in a ceremony in February 2022 to mark the first time Mauritius had led an expedition to the territory since the expulsions.
