"UK Hands Over Chagos Islands to Mauritius While Securing Strategic U.S. Military Base in Diego Garcia Amid Political Outcry and Global Security Tensions"
In a historic shift with global implications, the United Kingdom has officially transferred sovereignty of the Chagos Islands to the Republic of Mauritius in an agreement hailed by some as a monumental victory for decolonization and by others as a strategic maneuver to retain Western influence in the Indian Ocean. The move, which follows years of legal disputes and international pressure, notably includes provisions allowing the U.K. and its closest ally, the United States, to maintain control over Diego Garcia—the largest island in the Chagos Archipelago and the site of a critical U.S. military base—for at least the next 99 years. British Prime Minister Keir Starmer signed off on the deal asserting that it guarantees national and allied security, supports intelligence operations, and cements a longstanding military partnership with the United States. The base at Diego Garcia has been used for various high-stakes missions, including anti-terror operations in the Middle East and surveillance across Asia, making it one of the most valuable strategic outposts outside continental NATO. The deal involves the UK paying over $100 million annually to Mauritius for the lease of Diego Garcia, a move Starmer described as "value for money" when weighed against the strategic benefits of sustaining Western military dominance in a region where China has been growing its naval and commercial footprint. U.S. Secretary of State Marco Rubio praised the agreement and said President Donald Trump fully supported it during his February meeting with Starmer in Washington, calling the deal a “monumental achievement” for democracy and military cooperation. Mauritius’ Prime Minister Navin Ramgoolam, celebrating what he called a “complete decolonization,” emphasized that his nation’s sovereignty over the entire archipelago is finally recognized, correcting what he called a historical injustice. However, despite these diplomatic accolades, controversy continues to swirl, especially among the Chagossian diaspora and within the British Parliament. Thousands of native islanders, known as Chagossians, were forcibly removed from the islands in the late 1960s and early 1970s to make way for the military base, and many still live in exile, primarily in Crawley, Sussex, in the southeast of England. Critics argue that the new agreement, while addressing international legal mandates, does little to correct the human cost of displacement or offer a clear path for the return of Chagossians to their ancestral homes. Labour MP Peter Lamb, representing Crawley, voiced deep concern in Parliament, questioning the moral standing of the UK in supporting self-determination for Ukraine while denying it to its own displaced citizens. "What should I tell my Chagossian constituents?" he asked. On the political right, the backlash was even more severe. Conservative leader Kemi Badenoch accused Starmer's government of undermining British sovereignty and national defense, warning that Mauritius' growing ties with China could jeopardize intelligence operations and Western security interests. "Only Keir Starmer’s Labour Party would negotiate a deal where we pay to give something away," she declared. Populist leader Nigel Farage echoed these sentiments, suggesting the agreement “plays directly into China's hands” at a time when geopolitical rivalry in the Indo-Pacific is intensifying. From a legal perspective, this agreement aims to comply with a 2019 advisory opinion by the International Court of Justice and a 2021 ruling from a United Nations maritime tribunal, both of which deemed the UK’s hold on the islands as illegitimate and called for the completion of the decolonization process. Though the ICJ’s ruling is not legally binding, it has had significant diplomatic impact, bolstering Mauritius' campaign and drawing support from many nations within the African Union and beyond. The new agreement includes economic incentives and development funding for Mauritius, but it explicitly excludes any commitment to resettle displaced islanders on Diego Garcia, which remains under tight military control. U.S. officials also remained firm on the need to keep Diego Garcia operationally exclusive due to classified activities conducted there. In a press briefing, Prime Minister Starmer insisted the base is “vital for British and American forces” and “critical for neutralizing threats in unstable regions like the Middle East and Southeast Asia.” According to military analysts, Diego Garcia serves as a launchpad for both strategic bombers and reconnaissance aircraft, and its location allows the rapid deployment of naval assets across the Indian Ocean, Africa, and Asia. The UK's role in leasing it from Mauritius while maintaining operational authority ensures the continuity of Five Eyes intelligence-sharing between the US, UK, Canada, Australia, and New Zealand. Some Chagossians have cautiously welcomed the deal, hoping it might open the door for future negotiations over resettlement and citizenship rights, but others are dismayed. Olivier Bancoult, a long-time Chagossian activist, said in an interview that the agreement “makes peace with governments but not with the people who were harmed.” Campaigners argue that without guarantees for a right of return, cultural restoration, or reparations, the deal remains a geopolitical transaction that leaves humanitarian concerns unresolved. Human rights groups and former colonial legal experts have also weighed in, warning that the UK’s decision to prioritize military strategy over indigenous rights could damage its international image, especially at a time when it is championing democratic values and the rule of law globally. Meanwhile, in the town of Crawley, community members held vigils and meetings this week, expressing concern over being left out of the process and asking whether future generations will ever be allowed to return to their homeland. Starmer’s government maintains that while Chagossian welfare remains a “concern,” the immediate focus must be on global security and upholding strategic alliances in a volatile world. Supporters of the agreement argue that with tensions rising in the South China Sea, the Red Sea, and around Taiwan, Western military preparedness must not be compromised by delays over territorial disputes, especially when those disputes have legal settlements that enable continuity in security arrangements. British defense officials note that China has been ramping up its influence across the Indian Ocean, funding port developments in Sri Lanka, Pakistan, and parts of East Africa, and the Diego Garcia base represents a critical counterbalance to Beijing’s maritime ambitions. As this deal unfolds, its ripple effects are likely to be felt across global forums including the United Nations General Assembly, the African Union, and the Commonwealth. Whether it marks a progressive step toward reconciling colonial legacies or a contentious bargain that trades justice for strategy, only time will tell. The debate in Parliament is far from over, and Chagossians say their struggle for recognition and restitution will continue. Meanwhile, the geopolitical chessboard of the Indian Ocean has been reshaped by a deal that seeks to blend diplomacy with defense, morality with militarism, and history with hard choices—one that may define the legacy of Britain’s 21st-century foreign policy.
