Diego Garcia Military Base and British Indian Ocean Territory Bill

Phil Brickell Excerpts

2nd reading
Tuesday 9th September 2025 Commons Chamber

[Luke Pollard]

I say politely to the hon. Gentleman—for whom I have a lot of time, and I respect his military service—that that comparison we have seen of the British Indian Ocean Territory with the Falkland Islands is shameful. I have seen the tweets from the Conservative party asking, with a map of the Falkland Islands, “Are they next?”—a shameful comparison, which stokes the flames of division and threatens the sovereignty of such overseas territories. Let me be clear, as my hon. Friend the Member for Cardiff South and Penarth from the Foreign Office has been clear at the Dispatch Box: there are no changes or implications for any other British overseas territories. Indeed, the British overseas territories support the deal. I hope that we will not need to revisit this again, but any implication that seeks to apply the experience of BIOT to other overseas territories is unhelpful to them. I am certain that the hon. Gentleman wishes to create no question marks over those overseas territories.

[Phil Brickell (Bolton West) (Lab)]

To go back to the point that the Minister was making earlier about control, can he confirm to the House that, contrary to the reasoned amendment in the name of the hon. Member for Clacton (Nigel Farage), we are not ceding control of the Diego Garcia military base, consistent with clause 3?

[Luke Pollard]

My hon. Friend is exactly right. On the reasoned amendments, my colleague who is to conclude the debate, the Minister of State, Foreign, Commonwealth and Development Office, my hon. Friend the Member for Cardiff South and Penarth, will respond to some of the details of the reasoned amendment selected by Mr Speaker. However, there is a lot of misinformation about this treaty, and I believe that in some cases it is deliberate misinformation to confuse the picture. Clearly, securing the operation of the base is the priority of this Government and of this treaty. Indeed, I believe in good faith that it was the priority of the previous Government as well, which is why they started the negotiations and held them for 11 rounds, and why we concluded them, because we agreed with the previous Government that securing the future operation of the base was the priority. That is why they started them; that is why we completed them.

[Priti Patel]

My hon. Friend is right. At the end of the day, the real judge of this will be the British people.

[Phil Brickell]

Will the right hon. Member give way?

[Priti Patel]

No, I am answering my hon. Friend. The real judge will be the British people. How will they view a Labour Government giving away £35 billion to a foreign Government? That money could be spent in this country. It is simply not acceptable at all.

[Phil Brickell (Bolton West) (Lab)]

It is a pleasure to speak in support of the Bill, which safeguards our national security and protects our constituents.

Diego Garcia is one of the most important military bases in the world. From that facility, Britain and the United States project stability across the Indian ocean, the Gulf and the wider Indo-Pacific. The base has been vital in the fight against terrorism and piracy for many years. Today, it is indispensable in containing the growing reach of the Chinese Communist party, as others have said. Beijing is building ports, airports and naval outposts right across the region; its so-called “string of pearls” is designed to encircle and dominate. If we are serious about standing up for the values that we hold dear—human rights, democracy and, at its heart, freedom—Diego Garcia must remain secure and undisputed, which can be achieved only through the treaty that the Government have concluded.

Conservative colleagues may huff and puff, as they have been doing ad nauseam over the past few hours, but let us not rewrite history. As has been pointed out, it was not Labour that opened negotiations with Mauritius.

[Dr Luke Evans]

Will the hon. Member give way?

[Phil Brickell]

I will make some progress, if I may. I wanted to intervene on Opposition Members earlier, but was not allowed to.

It was the Conservatives who rightly described the situation in 2022 as unsustainable, and it was they who held 11 rounds of talks on sovereignty. In 2023, when he was Prime Minister, the right hon. Member for Richmond and Northallerton (Rishi Sunak) said that he wanted to conclude a deal soon. At the time, when they were in government, Conservative Members recognised that the base’s legal status was under serious threat, and that an interminable sovereignty dispute risked paralysing operations.

Let me make a quick point about international law. In reflecting on the ICJ advisory opinion, the right hon. Member for Witham (Priti Patel) said that it is an international court that few have heard of. Those kinds of reckless throwaway remarks undermine the United Nations’ highest judicial organ. She mentioned that we are a permanent member of the UN Security Council. There are judges sitting in the ICJ who are elected by members of the General Assembly, and through the Security Council. Although we have had judges sitting in that international court since its inception, we have not since 2018, which is a source of much shame for the country at large. I hope that she will take back those remarks denigrating the international system of law that underpins our international work. Let us not forget, after all, that in the 1940s, the United Kingdom was the first country to submit a case for arbitration by the ICJ. [Interruption.] I ask those Opposition Members who are chuntering: where were you when those 11 rounds of negotiations took place? I know that two years is a long time in politics, but have you already forgotten—

[Madam Deputy Speaker (Caroline Nokes)]

Order. I wasn’t anywhere, and I have forgotten nothing. Will Members please be careful about the language they use in the Chamber?

[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.
