Diego Garcia Military Base and British Indian Ocean Territory Bill

Peter Prinsley Excerpts

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

[Nigel Farage (Clacton) (Reform)]

Before I speak to amendment 10, which stands in my name on the amendment paper, I have a quick reminder: the International Court of Justice made an “advisory” judgment—it has no force in law. Quite why the previous Government sought to enter 11 rounds of negotiation off the back of it is beyond me, but it is even more extraordinary for a Government that is full to the rafters with human rights lawyers. They believe in human rights so much that somehow they are seeking to follow a court that is part of the United Nations in total contrast, as the hon. Member for Surrey Heath (Dr Pinkerton) pointed out, to one of the most basic principles of the United Nations: namely, national self-determination. We thought it mattered so much 40 years ago that we sent a taskforce 8,000 miles away to defend the rights of the people of the Falkland Islands.

I feel great sympathy for the Chagossians. They got a rotten deal 50 years ago, and in many ways they are perhaps getting an even worse deal now. They should be consulted. The fact they are not being consulted is shameful for a Government who go on endlessly about human rights and the international rule of law. That is the human cost of this.

As to the economic cost, well, lots of sums have been bandied about, from £3.4 billion from the Prime Minister to £35 billion, but it all depends on the rate of inflation. If the average rate of inflation over the next 100 years is 3%, it will be over £50 billion, but that may be as nothing to the opportunity loss here. This marine park should have been turned decades ago into the greatest marine tourism site in the world.

The hon. Member will be aware that his friend President Trump is in favour of this deal, so would he tell us whether he disagrees with him?

[Blake Stephenson (Mid Bedfordshire) (Con)]

Since this House first learned of the disastrous terms of the Chagos surrender deal, there has been significant focus on the spiralling cost and on the defence and security implications—we have heard many such arguments today. The Government’s weakness has compromised our national security. They are surrendering British territory to an ally of China and paying £35 billion—or perhaps as much as £50 billion—for the privilege. Their failure to defend the British national interest is shameful.

Equally shameful is the Government’s failure to consider the impact that the deal will have on environmental protections for marine areas. Members from across the House have reflected on that today, but it is a shame that so few Labour Members came to stand up for our environmental protections in the Indian Ocean Territories. I will address the importance of new clauses 3 and 4, two sensible amendments tabled by the shadow Foreign Secretary to strengthen oversight of the marine protected area.

The region of the Indian ocean that hosts the unique and remarkable Chagos Islands is of critical importance to wildlife. The archipelago is a biodiversity hotspot. The 640,000 sq km marine protected area, which has been monitored by the UK for the past 15 years, has kept the surrounding waters in near-pristine condition. The coral reefs in the untouched marine protected area are some of the healthiest in the world. They are a sanctuary for marine life, including endangered species such as hawksbill turtles, green turtles and reef sharks, and they are located along hugely significant migratory routes for species of tuna, whales and seabirds. The remarkable resilience of the reefs to coral bleaching events also makes them highly significant for scientific research to better understand resilience to changing climates.

[Peter Prinsley]

Like me, the hon. Member is a new Member, so I am puzzled: why does he consider that his party started these negotiations, if the whole thing is such a terrible idea?

[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.
