Diego Garcia Military Base and British Indian Ocean Territory Bill

Debate between Blake Stephenson and Sammy Wilson

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

[Blake Stephenson]

There is a difference between talking with other countries and doing a deal. I know that those on the Opposition Front Bench who formed part of the previous Government were not going to do this deal. They may have been talking, but as we have heard, there was going to be no agreement. I thank the hon. Member for his intervention and reflecting that I was not part of the previous Government, but he knows full well that this agreement would not have been made under these terms if the Conservatives were in government now.

The marine protected area is one of the largest untouched marine ecosystems, and it is globally significant. As such, instead of heedlessly driving this hopeless surrender deal through Parliament, the Government should have been ensuring that protections for wildlife and the marine environment were watertight. When answering questions before the Foreign Affairs Committee in June, the Minister would not give any clear assurances or guarantees on the future of the marine protected area. Within his obfuscation about separate agreements with Mauritius, which hope we can “share objectives and values”, he admitted that we can only

“take it on trust that there will be a Marine Protected Area”

after sovereignty has been surrendered.

We absolutely do not need to take that on trust. The Government have failed to secure any meaningful safeguards or guarantees, and are instead hoping—merely hoping—that a memorandum of understanding will somehow protect that pristine ecosystem. How on earth can we have any confidence in that at all?

A simple change of Government in Mauritius, or even just a change of heart, would render the UK powerless to stop Chinese trawlers turning up and devastating the marine environment. Given the evidence of China plundering the high seas, for example in the south Atlantic, just outside the Falkland Islands zone of economic interest, it absolutely will do the same in that territory.

[Sammy Wilson]

The hon. Gentleman is making a powerful point about the marine environment in the area, but does he accept that we do not even need a change of heart by Mauritius? We do not need it to decide that the treaty was not worthwhile—it does not have the ability to give the protection. Even if there was no change of heart, there is no ability to give such protection, which is why this is a bad deal for the environment.

[Blake Stephenson]

I absolutely agree, and I note that the right hon. Gentleman and I are the only Members in the Chamber from the Environmental Audit Committee, which I think is a damning indictment on those Members in this House who are here to protect our environment and hold the Government to account on environmental protections.

Will the Minister now explain what will happen to the MPA in future, and say whether the Government will commit resources to support the protection of the MPA? If so, where will those resources come from? With the fisheries Minister of Mauritius talking of issuing fishing and trawler licences, it is more important than ever that we have lasting confidence in marine protections before British territory is surrendered to Mauritius. When the Minister sums up the debate, will he say whether he shares my concerns over new fishing and trawler licences?

New clause 3 would require that any written instrument on the establishment and management of the marine protected area be subject to the approval of this House to ensure that it is fit for purpose. Will the Minister say what progress has been made with developing the “separate…instrument”, referenced in article 5.2 of the treaty? Will it be in place before Mauritius assumes sovereignty? Any agreement on the Chagos MPA must be scrutinised like a treaty and presented to Parliament.

New clause 4 would require the Secretary of State regularly to report on the status of the marine protected area. Reports from Committees in the Lords have raised concerns about Mauritius’s track record on environmental protections. Does the Minister agree with those concerns, and therefore agree that the ecological status of this extraordinary environment must remain on the British Government’s agenda, and will he reflect on that in his summing up of the debate? Will he now accept that, as well as costing British taxpayers £35 billion, betraying British Chagossians and undermining our security, without better protections secured in the treaty, the Government’s Chagos surrender deal will harm the marine environment? All of this at a time when the Government argued that the state of public finances required tough choices—choices that punished pensioners, family farmers, and taxed education for the very first time.

The annual cost of the surrender of the Chagos islands could pay for 3,068 new teachers, 3,253 new nurses or 1,975 police officers. In the first year, the money paid to Mauritius could deliver a new GP surgery in 30 communities —communities such as Wixams and Wootton in my constituency of Mid Bedfordshire, which are still waiting for improved access to local healthcare. This was all a choice—a choice to prioritise ideological surrender over our communities, over our security, and over marine protections. It is shameful, and I encourage hon. Members across the House to support new clauses 3 and 4.
