Diego Garcia Military Base and British Indian Ocean Territory Bill

Al Pinkerton Excerpts

2nd reading
Tuesday 9th September 2025 Commons Chamber

[Luke Pollard]

I agree with the right hon. Gentleman about the way the Chagossians were treated. For those who have a copy of the treaty to hand, part of the preamble says that the parties are

“Conscious that past treatment of Chagossians has left a deeply regrettable legacy, and committed to supporting the welfare of all Chagossians”.

That is in the treaty because their treatment was unacceptable, as he has explained, and it has caused a legacy of pain and suffering for that community. It is the reason why the Foreign Office Minister, my hon. Friend the Member for Cardiff South and Penarth, has engaged so much with the different views of a range of Chagossian voices in this debate.

I will come on to answer the right hon. Gentleman’s question when the interventions slow down a wee bit but, to get ahead of that, people will be able to visit Diego Garcia. Chagossians will be able to visit Diego Garcia as part of this treaty, which they are not currently able to do, but they will not be able to reside on Diego Garcia. They will be able to do so on some of the outer islands, for which the provisions will be different, but the military base is a military base for a reason, and although people will be able to visit, they will not be able to reside there. I will come back to that in due course.

[Dr Al Pinkerton (Surrey Heath) (LD)]

Will the Minister give way?

[Luke Pollard]

If the hon. Member does not mind, I will come back to him when I deal with the Chagossians later, but in the meantime I am happy to take the other intervention.

[Luke Pollard]

I will come back to the hon. Gentleman in a moment.

Although the Chagossians could not be part of the negotiations as they were conducted on a state-to-state basis, both the Minister of State, Foreign, Commonwealth and Development Office, my hon. Friend the Member for Cardiff South and Penarth (Stephen Doughty), and Foreign and Commonwealth Development officials have met and had regular meetings over the past year, and stayed engaged with their diverse views. There are diverse views within the Chagossian community that are strongly held, and we have listened and respected those.

[Dr Al Pinkerton (Surrey Heath) (LD)]

As some Members laugh about the nature of the 99 years and other Members talk about the sums of money involved, I ask all of us to look at the Public Gallery to remind ourselves that there are Chagossians here today who feel deeply aggrieved by the deal. They feel that the Foreign Office and this Government have not gone above and beyond to consult all the groups involved. The Minister said that this deal does not refer to other overseas territories, but the principle of self-determination of our overseas territories’ citizens—

[Madam Deputy Speaker (Judith Cummins)]

Order. Interventions need to be brief.

I will not. I experienced the right hon. Gentleman defending the hereditary principle last week, and I do not think I have the strength in me this week to listen to another argument.

The final test was on costs and obligations. Again, Ministers have talked powerfully about the deal being less than 0.2% of the defence budget. Comparisons have been made with what the French are paying in Djibouti, and I am glad that we are getting a better deal than the French. Of course, Diego Garcia is 15 times larger than those bases and in a more strategic location. The treaty gives us immense operational freedom. It therefore seems to me that this is a modest investment for an irreplaceable asset. The risks from delay or abandonment—in this argument, we have to balance the treaty with the risks of what could happen—are vastly greater.

[Dr Pinkerton]

The hon. Gentleman describes Diego Garcia as an irreplaceable asset, but the Chagossians sitting in the Gallery do not see it as an asset; they see it as their home. Even though they have been displaced from their home for the best part of 50 years, they tell me that they see the actions in the Chamber as a new round of the same colonial humiliation they experienced in the 1960s and 1970s. What does the hon. Gentleman say to those Chagossians here today?

[Tim Roca]

I thank the hon. Member for raising that important aspect. We should all be honest that, as was put powerfully by my hon. Friend the Member for Crawley (Peter Lamb), our country’s history with the Chagossians has been very poor—if we look at some of the diplomatic cables from the 1960s, we see that disgraceful language was used—but I was reassured by what Ministers said about the preamble of the treaty and some of the provisions put in place.

It is a matter of fact that the previous Government were in negotiations with Mauritius over this issue. That was the case, and there will have been motivations for their doing that. I am worried about how our other overseas territories are being dragged into this. A couple of months ago, I was in Gibraltar with colleagues who privately told me they were horrified that party politics were being played with their communities. I am glad to see that Gibraltar’s Chief Minister was clear on the record that there was “no possible read across” to Gibraltar, and the Governor of the Falklands said that the

“historical contexts…are very different.”

I am confident that we meet the three tests.

[Phil Brickell]

Thank you, Madam Deputy Speaker.

Labour has finished what the previous Government started—what was left to us after former Prime Minister Liz Truss let the genie out of the bottle in starting negotiations with Mauritius in 2022. That was reported, and much maligned, by Matthew Parris in The Spectator at the time—let us not forget that. This Government have sought to strike a deal in Britain’s best interests, given the legal mess that they inherited. Let us be clear: this agreement secures the future of the Diego Garcia base. Britain retains control of the base, as the Minister confirmed in response to my intervention near the start of the debate. There is a protective buffer zone, and no foreign security forces will be on the outer islands. There will be a robust mechanism to prevent interference, and for the first time, Mauritius has agreed back the base’s operations. That is a huge strategic win.

What about cost? Let us get this clear, because some of the disinformation coming from the Conservative party is concerning; it is unnecessarily setting hares running about the future of other British overseas territories, including the Falkland Islands and Gibraltar. The overall cost has not changed from that negotiated with the former Mauritian Prime Minister, and suggestions to the contrary are simply false. When set against the cost of inaction, the financial component is modest. It is far cheaper than the spiralling costs of legal uncertainty, and far cheaper than the price we would pay if Chinese expansionism went unchecked in the Indian ocean. For a fraction of our defence budget, we will secure a cornerstone of global stability. Let us not forget that the agreement will have an average annual cost that represents 0.008% of total Government spend, according to the Government Actuary’s Department.

[Dr Pinkerton]

Earlier in his very carefully crafted speech, the hon. Gentleman said that this deal protects freedom. One of the freedoms that citizens of the British overseas territories to which he referred most appreciate is the freedom to determine their own future. Why does he think that Chagossians should be made an exception and denied the right to determine their own future?

[Phil Brickell]

I am sure that the Minister will come to that in his closing remarks. I have to concur with other Members that the way the Chagossians were treated in the ’60s and ’70s was utterly shameful. I am proud that there will be rights of return, and the ability to visit.

Conservative Members claim to be the champions of defence, but that is not borne out by the facts, which include an 18% cut in defence spending in their first five years in government, and their shrinking the Army to its smallest size since the Napoleonic era. In how many years out of 14 was the target of 2.5% of GDP spent on defence hit? Zero. They should not lecture Labour Members on national security. The Government’s plan is straightforward, transparent and serious. We have the largest increase in the defence budget since the cold war; we are rebuilding alliances that previous Governments wantonly vandalised; we are acting where there was dither; we are governing in the national interest; and, importantly, we are securing the long-term future of the Diego Garcia base.

It is clear that a binding adverse judgment against the UK was inevitable. Since 2015, 28 international judges have expressed views on Chagos sovereignty. That was under the previous Government, and not one of those 28 judges backed Britain’s claim. Without an agreement, our ability to operate the base would have been compromised. Overflight clearances would have been at risk, contractor access would have been uncertain, communications would have degraded, costs would have soared, and investment would have fallen. Who would that benefit? I put that to Conservative Members, but I will give them a clue: it is not Britain, and not Britain’s allies. This deal secures Diego Garcia, cements our role in the Indo-Pacific, strengthens our ability to push back against Chinese influence, and shows that Britain is a dependable ally that takes national security seriously.

I wish to make a closing remark on the reasoned amendment by the Reform party, in the names of the hon. Members for Clacton (Nigel Farage), for Boston and Skegness (Richard Tice), for Runcorn and Helsby (Sarah Pochin) and for Ashfield (Lee Anderson), who seem not to be present. I will read out a part of it that I am gobsmacked nobody has picked up on in this debate:

“because the reason for the UK-Mauritius Treaty and for bringing forward this Bill follows a judgment from the International Criminal Court, from which the UK does not recognise judgments as binding, only advisory”,

they will oppose this Bill. I want Reform to answer: which case before the International Criminal Court is it referring to? Is Reform suggesting that, were it to come to power, it would not recognise the binding judgments of the International Criminal Court? Will it take us out of the ICC? Unfortunately, Reform Members are not here to respond.

The Conservatives opened the door to this treaty. Labour inherited a legal mess, but it has delivered a deal in the long-term national interest. For a small cost, we have achieved a huge strategic win. That is why I am proud to support this Bill, and I will vote with the Government tonight.
