Mounting Chaos Over Starmer’s Chagos Islands Handover

The Labour government’s decision to cede sovereignty of the Chagos Islands to Mauritius has spiralled into a full-blown political crisis for Sir Keir Starmer. What was intended as a "clean break" from a long-standing colonial dispute has instead ignited a firestorm involving national security concerns, disgruntled islanders, and a growing rebellion within his own backbenches.

As of late February 2026, the fallout from the deal—which sees the UK give up the British Indian Ocean Territory (BIOT) while retaining the strategic Diego Garcia airbase on a 99-year lease—is threatening to overshadow the government’s wider foreign policy agenda.

The Security "Sieve"
The primary criticism levelled at Number 10 is the potential for Chinese influence in the region. Security experts have warned that once Mauritius takes control of the outer islands, there is "nothing in the contract" to prevent them from leasing land to Beijing for surveillance hubs just miles from the UK-US base.

The US Stance: While the Biden administration initially offered tepid support, the mood in Washington has shifted. US defence officials are reportedly "deeply uneasy" about the long-term viability of Diego Garcia if the surrounding waters are no longer under British jurisdiction.

The "Gibraltar & Falklands" Fear: Critics argue that by "surrendering" Chagos, Starmer has sent a signal of weakness to Madrid and Buenos Aires, potentially jeopardising other British Overseas Territories.

The Betrayal of the Chagossians
Perhaps the most damaging optics for the government come from the Chagossian people themselves. Despite the government's rhetoric of "rectifying historical wrongs," many islanders feel they have been traded like "pieces on a chessboard."

Excluded from the Table: Representatives of the displaced community claim they were not consulted on the final terms of the deal.

The Right to Return: While the treaty allows for a "programme of resettlement" on the outer islands, many Chagossians are skeptical of Mauritius's ability to fund and protect their return, with many preferring to remain under British sovereignty.

Parliamentary Pushback
Inside Westminster, the "chaos" is palpable. The Conservative opposition has branded the deal a "shameful capitulation," but more worryingly for Starmer, several Labour MPs have expressed private dismay over the "rushed" nature of the announcement.

"We are essentially paying Mauritius to take territory that we then have to rent back from them," noted one senior backbencher. "It’s a diplomatic riddle that doesn't benefit the British taxpayer or the islanders."

The Legal Quagmire
The deal is now facing a series of High Court challenges from Chagossian advocacy groups. Lawyers argue that the sovereignty transfer is "constitutionally invalid" without a referendum of the people actually from the islands. If these legal hurdles hold, the "spring handover" promised by the Foreign Office may be delayed indefinitely.
