British Indian Ocean Territory

Priti Patel Excerpts

Wednesday 2nd April 2025 Commons Chamber

[Priti Patel (Witham) (Con)]

(Urgent Question): To ask the Secretary of State for Foreign, Commonwealth and Development Affairs if he will make a statement on the status of the negotiations surrounding the future sovereignty of the British Indian Ocean Territory.

[The Minister of State, Foreign, Commonwealth and Development Office (Stephen Doughty)]

I thank the right hon. Lady for her question. As we and Mauritius have repeatedly said, including in joint statements on 20 December and 13 January, both sides remain committed to concluding a deal on the future of the Chagos archipelago that protects the long-term effective operation of the joint UK-US base on Diego Garcia. We are now working with Mauritius to finalise the agreement, and although it is in everybody’s interest to progress the deal quickly, we have never put an exact date on it, and we do not intend to do so now. Following signature, the Government will bring forward a Bill to enable the implementation of the treaty, and Parliament will of course have the opportunity to scrutinise the treaty in the usual way before ratification.

I repeat that the Government inherited a situation in which the long-term future of the military base was under threat. This deal is rooted in a rational and hard-headed determination to protect UK security and that of our allies. It will protect the base on Diego Garcia, and cement the UK and US presence in the Indo-Pacific for generations to come.

Thank you, Mr Speaker, for granting this urgent question. It is incredibly disappointing that, only a day after Foreign Office oral questions, Ministers have had to be hauled back to the House to explain what is going on. Yesterday at lunch time, Downing Street briefed that the agreement between the UK and Mauritius, under which the UK would give away the Chagos islands and pay for the privilege, has been finalised. That was not said in this House yesterday. The Prime Minister of Mauritius has also issued a public statement confirming that. Despite being interrogated on this botched deal in the Chamber yesterday, Ministers gave no indication of this very significant development.

We are still completely in the dark about fundamental questions of enormous importance. How many billions of pounds of hard-pressed British taxpayers’ money will we be expected to fork out to lease back territory that we already own? This comes as vulnerable pensioners are having their winter fuel payments ripped away, and family farms and businesses are being punished with new taxes by this Labour Government. What safeguards will be in place to protect the military base on Diego Garcia from other states that may try to establish a foothold on the archipelago? Ministers have so far refused to publish even a map of the buffer zone. What happens to the vital military base on Diego Garcia at the end of the treaty, and what kind of sovereign rights, if any, will we be able to exercise over Diego Garcia in the meantime?

The Prime Minister of Mauritius says that he forced changes to the arrangements on the exercise of sovereign rights and the lease extension. Will the Minister finally confirm that the account given by the Prime Minister of Mauritius is correct? He cannot simply stand here and avoid these questions. The House does deserve answers; so do the British public—the taxpayers. Put simply, the British Indian Ocean Territory should remain British, but Labour has prioritised appeasing the whims of left-wing lawyers and activists, rather than standing up for our national interests. It is high time this deal was ditched.

Finally, there have been reports of implied military threats to the Chagos islands, a British sovereign territory—Labour Members may laugh, but this issue is fundamental to the security of our country—from the regime in Tehran. The Iranian regime has threatened this space. These purported military threats are important. We understand that, in response to such reports, there has been an unusual build-up of American bomber aircraft and equipment-carrying aircraft at the joint UK-US military base on Diego Garcia. This is very serious, and we clearly need to take these threats seriously. We would welcome clarity about the Foreign Office’s diplomatic response on this issue.

[Stephen Doughty]

On parliamentary accountability for this issue, I have answered no fewer than five urgent questions on the subject in the last six months, and I have answered 130 written questions from her and her colleagues. We discussed this twice at Foreign, Commonwealth and Development Office questions yesterday. As I have repeatedly said, when the details of the treaty are finalised, it will be presented to this House, and there will be full scrutiny in the usual way. I have explained that a Bill will be brought in to put into force the important aspects of the treaty that require legislative change, and there will of course be full debates, as there should be, in this House.

I simply reject the basis of much of the right hon. Lady’s question. As I have said repeatedly, if there was not a problem, why did the Government of whom she was a part start negotiations, and go through 11 rounds of them? There is a significant challenge, and this deal is paramount for our national security. We will not scrimp on our security, and it is important that the deal is put in place, as has been recognised by all the parties.

We will only agree a deal that is in the UK’s best interests and protects our national security. Importantly, the right hon. Lady asked about the security provisions to protect the base. These will include full UK control over Diego Garcia, including control of the electromagnetic spectrum, and unrestricted access to and use of the base, as well as a buffer zone around Diego Garcia in which nothing can be built or put in place without our consent. There will be a robust mechanism and review process to ensure that no activity on the outer islands can impinge on the base’s operations. Indeed, there will be a prohibition on the presence of foreign security forces, either civilian or military, on the outer islands. As the Prime Minister has said, the full details will of course be set out when the treaty is laid before Parliament, and that will include costs. We will not scrimp on security.

The right hon. Lady asked an important question in relation to Iran. She will understand that for operational reasons and as a matter of policy, we do not offer comment or information relating to foreign nations’ military aircraft movements or operations. The UK, in close co-operation with our allies in the United States, closely monitors the security environment in the Indian ocean region to identify and mitigate any potential threats to the base on Diego Garcia.
