Diego Garcia Military Base and British Indian Ocean Territory Bill

Aphra Brandreth Excerpts

Tuesday 20th January 2026 Commons Chamber

[Sammy Wilson]

Most people listening to this debate, even if they do not know a great deal about the Chagos islands and the base, will understand that we have handed over the islands when there was no necessity to do so, only to use taxpayers’ money to lease them back. That is one of the scandals of the treaty.

The Minister talked about building a relationship of trust with the Chagos islanders. What way is this to build trust? The Government have refused to give them a say on whether this treaty reflects their interests and deals with their concerns and the despicable way in which they have been treated in the past. The cost is wrong. The way in which we are treating the people who are affected by the treaty is wrong. The Government’s position on the long-term security of the base is wrong. This is a bad deal for the United Kingdom, and we should be ashamed that the Government’s majority is being used to push the deal through when it is so clear that it is full of flaws and problems for our future.

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

The Bill goes to the very heart of our national security, the safety of the British people, our global reach and our operational effectiveness in two of the most volatile and unpredictable regions of the world: the Indo-Pacific and the middle east. It also raises serious questions about the cost of this deal to the British taxpayer, which amounts to £34.7 billion.

Even in the short time since the Bill was first brought to the House, the world has become even more unstable, yet the Government remain content to press ahead with the Bill. I struggle to see how it makes us safer, considering the requirement “to expeditiously inform” Mauritius of operational activity, and considering that Mauritius is a signatory to the Pelindaba treaty. The implications of the Bill for the basing of nuclear weapons, which are vital to our security and to our deterrence, and which have been deployed to Diego Garcia in the past, should concern every Member of the House. We need further clarity and assurance from the Government on that point.

That brings me to the £28 billion shortfall in the defence budget that the Chief of the Defence Staff recently presented to the Prime Minister. It does not take a mathematician to see the point that I am making; indeed, the maths is so basic that I suggest that even the Chancellor could work it out.

I will make progress, because we are nearly out of time. Instead of pursuing the Bill, the Government could withdraw it, and redirect the vast sums involved towards addressing that shortfall and genuinely strengthening our national security.

[Aphra Brandreth]

We are short of time. Ultimately, the Lords amendment is about accountability to Parliament and to the electorate. There is no mandate for the Bill. If the Government choose to force it through using their majority, they must, at the very least, be accountable for the cost.

British Chagossians are the forgotten people of this Bill. They may have been forgotten by the Government, but they have not been forgotten by Conservative Members. We continue to oppose the Bill with them firmly in our minds. The Prime Minister has rightly stated that Greenland’s sovereignty and right to self-determination rest with the people of Greenland and the Kingdom of Denmark. The question is simple: why is that same right not afforded to the British Chagossians?

The Bill has profound implications for our national security and public expenditure. The amendments tabled by Opposition peers are there for a reason: not for political gain, but to make a bad Bill slightly less damaging, to introduce safeguards, to offer some reassurance to the British taxpayer, and to ensure that the voices of the British Chagossian people are finally heard.
