Diego Garcia Military Base and British Indian Ocean Territory Bill

Debate between Aphra Brandreth and Sammy Wilson

Consideration of Lords amendments
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.
