The British government has formally announced a historic agreement to transfer sovereignty of the Chagos Islands to Mauritius, finalising a long-contested chapter in post-colonial history. The move, confirmed by Prime Minister Keir Starmer's administration, comes despite recent criticism from former US President Donald Trump, whose own government had initially backed the plan.
The Details of the Landmark Sovereignty Agreement
A binding deal, signed between the United Kingdom and Mauritius in May, sets out the terms for the handover. Crucially, it includes a provision for the UK to lease back the Diego Garcia atoll for a minimum of 99 years. This strategic island is home to a critically important US military base, ensuring continued operational continuity for Western defence interests in the Indian Ocean.
The archipelago has been under British control since 1814. In a controversial move in 1965, the UK separated the islands from Mauritius, three years before the latter's independence. To establish the US base on Diego Garcia, British authorities evicted up to 2,000 indigenous Chagossians from their homes, a forced exile that has sparked decades of legal battles and activism.
Addressing the Legacy of Displacement
Today, an estimated 10,000 displaced islanders and their descendants live primarily in the UK, Mauritius, and the Seychelles. For generations, this diaspora has campaigned for the right to return to their homeland. The new agreement seeks to address this painful legacy by establishing a resettlement fund specifically designed to assist Chagossians in returning to the outer islands of the archipelago.
It is important to note that the resettlement provisions explicitly exclude the Diego Garcia atoll, which will remain under the long-term lease for military use. The focus is on enabling communities to rebuild lives on other habitable islands within the Chagos chain.
Geopolitical Implications and the Path Forward
The British government has defended its decision as the correct legal and moral course, aligning with international court rulings that found the UK's continued administration unlawful. The deal represents a significant shift in UK foreign policy and its approach to colonial-era disputes. While the Trump criticism highlighted the political sensitivities around the US base, the 99-year lease is seen as a robust safeguard for its future.
This sovereignty transfer marks the beginning of a complex implementation phase, centring on the practicalities of resettlement and the ongoing strategic management of Diego Garcia. For the Chagossian people, it opens a cautiously hopeful new chapter in their long struggle for justice and the right to return.
