Diego Garcia Military Base and British Indian Ocean Territory Bill

Debate between Aphra Brandreth and Graham Stuart

Committee of the whole House
Monday 20th October 2025 Commons Chamber

[Graham Stuart]

The right hon. Gentleman is quite right to ask that question. That is what we are trying to get to the bottom of, and we hope to hear answers from the Minister this evening so that ordinary citizens of this country can understand how it is in the UK’s interest to do this.

Of course, other points have been touched on, including, quite rightly, the Chagossians. Why is the Labour party—the party so committed to human rights and which very much sees itself as champion for the underdog—absolutely disregarding the Chagossians? As the hon. Member for Bolton West suggested, Labour also sets itself out as a nature and climate champion, yet it is handing this asset over to a country without the wherewithal—I do not know about the will, but it is certainly without the wherewithal—to ensure that the protection of that marine area continues. That is the problem, and it is why we need answers from the Minister. The Government may be unable to get anyone to speak in favour of the Bill, but they should think again, accept the amendments and new clauses, and bring some light to bear on this rather murky issue.

[Aphra Brandreth (Chester South and Eddisbury) (Con)]

The treaty that the Bill will implement is shocking for so many reasons: the security implications, the staggering costs, and the voices that it has ignored—the voices of British Chagossians. Their views and concerns are many and varied. I had the privilege of meeting members of the community when they came to Parliament, while the former Foreign Secretary, the right hon. Member for Tottenham (Mr Lammy), met British Chagossians only once, and that was on the very day that the treaty was signed—far too late for their voices to have any influence. They are rightly frustrated that they have been excluded from negotiations and denied meaningful engagement. It is painfully clear that their voices were not considered; if they had been, the treaty might have placed their rights at its very centre.

Instead, article 6 gives Mauritius the freedom to resettle Chagossians, but not the duty to do so. After half a century of waiting for it, their right of return is left entirely at the discretion of a foreign Government. Under article 11, despite the billions of pounds that the Bill will transfer to Mauritius, only a fraction—in the form of a trust fund—is intended for Chagossians. Even then, it will be administered solely by Mauritius, with no guarantee that British Chagossians will have any say in how it is spent.

The treaty says that the UK and Mauritius want to

“recognise the wrongs of the past”,

but how can we recognise a wrong if we refuse to listen to those who suffered it? New clause 7, tabled by the shadow Foreign Secretary, my right hon. Friend the Member for Witham (Priti Patel), is vital because it would require the Government to listen to and consult the Chagossian community here in the UK, and to report back on how their rights are being upheld. That would give British Chagossians the voice that they have been denied again and again.

Another vital issue is the risk that the Bill poses to one of the most precious marine environments on earth. The waters around the Chagos Islands form one of the world’s largest and most pristine marine protected areas. As we have heard, it is a haven of biodiversity, untouched by industrial fishing since 2010. Yet the treaty places that fragile ecosystem in jeopardy. Mauritius has promised to establish a new marine protected area, but it lacks the capacity to enforce it. It has no navy, and its coastguard of nine vessels is already stretched by patrolling waters thousands of miles away. By contrast, the UK has spent over £1.2 million since 2022 on monitoring and protecting those seas, developing world-leading expertise in remote enforcement through ships, sensors and satellite imagery.

Illegal fishing is already rife across the Indian ocean. China’s distant-water fleet is the largest in the world and the worst global offender for illegal fishing, according to the illegal, unreported and unregulated fishing index. What confidence can we have that Mauritius—a close ally of China—will be able or willing to resist such pressure and protect these fragile waters?
