The Deputy Speaker who was in the Chair before me read out the statement, and I will do so again for clarity. Having given careful consideration to Lords amendments 2 and 3, Mr Speaker is satisfied that they would impose a charge on the public revenue that has not yet been authorised by this House. In accordance with paragraph (3) of Standing Order No. 78, the amendments will therefore be deemed to be disagreed to and are not subject to debate.

We cannot keep having the same discussion again and again. This is a very substantial debate and many people hope to speak, so let us proceed as fast as we can.

Thank you for clarifying that, Madam Deputy Speaker.

In parallel with the other measures, we have established a contact group to give Chagossians a greater say in UK Government support to their communities and we are in the process of enhancing that group, as Baroness Chapman committed to do in the other place. Thanks to the work we have done and the reasonable concerns raised across the House, the Chagossian trust fund will be operated for Chagossians by Chagossians. There will be a Chagossian majority on the board, which will include a UK-based representative and a Chagossian chair. Those reasonable concerns have been raised in the course of the debates and we are trying to address them.

Before I call the shadow Foreign Secretary, for the benefit of the House, and to provide a fuller response to the point of order raised by the right hon. Member for South Holland and The Deepings (Sir John Hayes), it is Lords amendments 2 and 3, which relate to the referendum, that will be disagreed to under Standing Order No. 78(3). The expenditure necessary for a referendum has not been authorised by this House. Lords amendments 5 and 6 are within the scope of the debate. Although amendment 6 engages the financial privilege of this House, it does not in itself involve any expenditure. I hope that helps colleagues.

On a point of order, Madam Deputy Speaker. I only want to clarify that point slightly. Those amendments are mentioned on the Order Paper, but cannot be voted on because of financial privilege, yet they are on the Order Paper, so surely they can be debated and discussed, without us having a vote at the end. Otherwise, they should not have been put on the Order Paper.

Nusrat Ghani Portrait Madam Deputy Speaker (Ms Nusrat Ghani)
- Hansard - -

The advice I am getting from the Clerk is that that is incorrect because the amendments were disagreed to in the Lords, so we must continue with the debate in hand, as on the Order Paper.

Labour’s Chagos surrender Bill is back, and this House has its last chance to act in the national interest, defend the rights of the Chagossian community and protect the money of hard-pressed British taxpayers, who are being expected to foot a colossal bill of £35 billion, which is being given to a foreign Government to—guess what?—cut their taxes, while our taxes rise.

I put on record the thanks of Conservative Members to the other place for their scrutiny, and their diligence in once again holding this Government to account. When Labour plotted to deny this House a debate and a vote on the surrender treaty during the 21-day process under the Constitutional Reform and Governance Act 2010, it was Conservatives in the House of Lords who forced a debate and a vote. When Labour limited the time for this House to give the Bill the line-by-line scrutiny it needed, it was the House of Lords that stepped in and made time available. When this Labour Government ignored and neglected the views of the Chagossian community, it was the House of Lords and the International Relations and Defence Committee that came to the rescue and organised a survey, giving important insights into Chagossians’ concerns about the Government of Mauritius and the future of their ancestral home. When Labour refused to accept any amendments to modify and improve this £35 billion surrender Bill, it was the House of Lords that made important changes, which we are debating today.

Let me be clear: this is a Bill that the Conservatives have fought against at every single stage. We will not accept this deal to surrender British sovereignty; it is a deal that we will continue to oppose and challenge Ministers on. Every vote today is a vote to kill this Bill. We will keep on voting against this Bill and opposing it until the Government—and, one would hope, the Prime Minister—see sense, withdraw it and tear up the treaty. We are not the only ones vociferously opposing this, because we now know that the President of the United States is against it; he says that it is being done “for no reason whatsoever”, and that China and Russia will

“have noticed this act of total weakness.”

On a point of order, Madam Deputy Speaker. May I correct the record? The hon. Member for Spelthorne (Lincoln Jopp) says that there are not any veterans. I have served this country as an Army reservist, and I am very proud to have done so. We have many other Labour Members who have served and are veterans; they absolutely defend the national security of this country and have done so at many different stages. That comment is not accurate and needs to be corrected.

Nusrat Ghani Portrait Madam Deputy Speaker (Ms Nusrat Ghani)

I thank—[Interruption.] Order. I can make a decision; I do not need any help. That was not exactly a point of order, Minister. It was much more of an intervention, which may have been taken by the Member who was about to rise to her feet. However, the Minister has got his point on the record. We need to move at a pace; otherwise, we will not get speakers in.

Priti Patel Portrait Priti Patel
- Hansard - - - Excerpts

Although Lords amendments 2 and 3 have not been selected, I will briefly comment on them for members of the Chagossian community watching this debate. Owing to the actions of the Conservatives in the House of Lords, the Government were forced to slow down the ratification process for a brief moment while a survey was undertaken in the other place by the International Relations and Defence Committee. That was very important, because something like 3,000 respondents gave a view. They gave a very clear statement as to the direction of travel on the Chagos Islands—their ancestral home—and they want them to remain British.

In answer to the intervention by the hon. Member for Spelthorne (Lincoln Jopp), there is more than one veteran on the Labour Benches. I wonder what the veterans from the Conservative party who went through 11 rounds of negotiations under the previous Government were saying; they clearly supported this decision at that point, and there were clear reasons for doing so.

This is not an exercise in process; it is about whether this House chooses to protect on firm, enforceable terms an overseas base that is fundamental to British security and our closest alliances. Diego Garcia is a critical asset for the UK and our allies. It supports counter-terrorism, monitors hostile state activity, and enables the rapid deployment of UK and US forces across regions that matter deeply to our national interest. Those opposing the Bill need to be clear about what they are opposing. They are opposing a treaty that secures the base for 99 years with full operational freedom, one that is backed by our allies and was negotiated substantially under the previous Government.

On a point of order, Madam Deputy Speaker—never has a point of order been greeted with such joy from the Chair—you have rightly pointed out, as has Mr Speaker, the Lords amendments that engage Commons financial privilege. We guard that privilege jealously and exercise it with caution. How is the House supposed to exercise that financial privilege in an informed way when, despite several probes to the Minister to come up with a figure for what this deal will cost the public purse, those right hon. and hon Members attending the debate this afternoon have not been given that figure? We have had a lot of theory about how a figure had been arrived at, but no figure. How do we exercise—

Nusrat Ghani Portrait Madam Deputy Speaker (Ms Nusrat Ghani)
- Hansard - -

Order. Mr Hoare, I am worried that the longer you speak, the longer you will disappoint other colleagues who are hoping to contribute later in the debate, and I would not want to ruin your reputation on that front. This feels like a continuation of the debate. The Minister may or may not wish to respond to that point during his closing speech, but my job is to make sure that as many Members as possible who have sat through this debate get to put their voice on the record.

I call the Liberal Democrat spokesperson.

Al Pinkerton Portrait Dr Pinkerton
- Hansard - - - Excerpts

I will do my best, having received that cue from you, Madam Deputy Speaker.

This Bill returns to us from the other place with amendments that raise serious questions about the governance, cost and durability of the treaty concerning the future of Diego Garcia and the wider Chagos archipelago. For decades, decisions about the Chagos islands were taken without the consent of the Chagossian people. That was the defining feature of the injustice that they have experienced. My concern, shared by many across this House and others in this place, is that unless the Government properly consider the Lords amendments, Parliament risks giving statutory effect to a framework that lacks the safeguards necessary for accountability, legitimacy and long-term sustainability. That is precisely what the Lords amendments seek to address.

In the things that they have proposed, the Government have acknowledged the historic wrongdoing to the Chagossian people. They have recognised the right of return in principle and proposed a £40 million trust fund to address the harms caused by forced displacement. The framework before us today provides limited assurance, however, that the Chagossian people will have any meaningful agency over the decisions and structures that will shape their future. That matters, because legitimacy is not derived from intergovernmental agreement alone. It rests on whether those affected can participate meaningfully in decisions taken about their homeland.

At the core of the United Nations charter lies the principle of self-determination. Article 1.2 could not be clearer. One of the purposes of the United Nations is:

“To develop friendly relations among nations based on respect for the principle of equal rights and the self-determination of peoples”.

We reasonably expected to have the opportunity to vote to reaffirm our commitment to the UN charter and, crucially, our commitment to the right of Chagossians as a distinct, albeit displaced people to self-determine their future. It is therefore deeply regrettable that Members across this House have been denied that opportunity today.

Iain Duncan Smith Portrait Sir Iain Duncan Smith
- Hansard - - - Excerpts

It does not really matter to me who is in government because I am in opposition. I was opposed to this then, so if the hon. Member does not mind, I am not going to try to defend any of that. I can tell him that I was far more opposed to it than many of his hon. Friends on the Back Benches are now. I hope I have now expunged any dishonour on my part.

On the two critical areas—UNCLOS and the ITU—we discovered that certain articles exempted us from any legal challenge in any way, and therefore they were not binding. I say that because today is a matter of intense sadness. As the Minister knows, I am a massive admirer of him for his steadiness and determination, often on unpopular matters. However, I have to say to him on Lords amendments 2 and 3, and the Liberal Democrats say the same, that this is a matter of sophistry. If we believe in free speech and free debate, and if we believe in voting on what we believe or what we oppose, I genuinely ask why we cannot do so on Lords amendments 2 and 3.

Sitting in the Gallery are people who will be utterly depressed by the idea that this Chamber has shut itself out from debating the rights of the Chagossians and to vote on those rights today. I know it was clever to get that done, and I know the Speaker’s Office was under pressure to do that, but I simply say that this is not right. It is not right that this House cannot decide on those rights, particularly given that the UN committee mentioned by the hon. Member for Blackley and Middleton South (Graham Stringer) has made it very clear that the Government should stay this legislation, because of its fears with regard to race relations.

I simply say that this is a sad moment for this House, because this horribly flimsy piece of legislation completely casts away any rationale. Then this morning we heard from the President of the United States, who was previously prayed in aid in all this; it was said that we should somehow motor through this because he was in favour of it, and if the American Government are in favour of it, we should stand with them. A previous Foreign Secretary said that if America did not want it and did not agree with it, we would not do it, but here we are rushing through with it.

Why are we rushing? Why do we not stay this Bill, wait to hear exactly what America thinks about it and make a decision about whether we carry on? Surely, that would make more sense and be more rational. Through all of this, I just do not get what the unpalatable haste is all about—to dismiss the Chagossians, to dismiss the logic and the reasons why we have to do this, and to head towards paying billions and billions of pounds of taxpayers’ money for no reason at all. I think somebody else said that today.

Meanwhile, China is looking at this and laughing, as are Russia, Iran and all the other nasty states. Honestly, this is a bad day. This is badly done. It is a bad day for us and for the concepts of dispute, debate and liberty. We should hang our heads in shame, because the House of Lords is better at debating things than we are, and it has much better rights.

Tom Hayes Portrait Tom Hayes
- Hansard - - - Excerpts

My hon. Friend the Member for Halesowen (Alex Ballinger) has said much of what I was going to say, thankfully, so I will try to be brief. The shadow Foreign Secretary, the right hon. Member for Witham (Priti Patel), made a set of arguments predicated on the case for national security. It is therefore important to take on the question of how secure we are. Look at the economic security that this Government inherited: 15 years of slow, weak growth, the lowest business investment in the G7, and wages that had grown at a consistent 2% a year flatlining. Look at the impacts of the Brexit deal negotiated by the Conservatives: in early 2025, the UK’s GDP was between 6% and 8% lower than it would have been without Brexit, and we lost between £180 billion and £240 billion of output. This is important, because it relates to the credibility of the Opposition when they make their case on the basis of national security.

Nusrat Ghani Portrait Madam Deputy Speaker
- Hansard - -

Order. Mr Hayes, this debate is about the issue in hand, not the credibility of the Opposition. Let us get to the point quickly.

Tom Hayes Portrait Tom Hayes
- Hansard - - - Excerpts

Moving forward three pages—those pages were a condensed history of how our country was left completely insecure by the Opposition—to look at Diego Garcia, it is a critical UK asset for national security. We all agree on that in the House. It supports counter-terrorism, monitors hostile states and enables rapid deployment of US and UK forces worldwide. That is, in large part, why the US Administration have backed what this Government have been pushing forward. Recent operations against high-value ISIS targets show its vital role in keeping global trade routes and the British people safe.

With this deal, we have full operational freedom. We have control of installations, communications, logistics and land use with strict safeguards, a UK-controlled electromagnetic spectrum, a 24 nautical mile buffer zone and a ban on foreign military presence on the outer islands. In the interests of giving a briefer speech, I am going to put down the two pages that further explain the way in which the treaty reinforces the UK’s relationship with the Chagos islands and supports our national security.

We have talked about this issue at great length. There have been many urgent questions, statements and debates in the House. The Opposition talk about the importance of national security. This country is facing some of the gravest threats to our national security. We are repelling Russian cyber-attacks and disinformation daily. Our security services are having to fight against Russian spying and sabotage of our infrastructure.

On a point of order, Madam Deputy Speaker. I am not sure which amendments are being addressed. There are at least five on the amendment paper to be talked about. I just wondered if Russia is relevant to any of those amendments.

Nusrat Ghani Portrait Madam Deputy Speaker
- Hansard - -

Dr Luke Evans, you need to stop using points of order to continue debates. No doubt Mr Hayes is going to get right to the point and then conclude very quickly.

Tom Hayes Portrait Tom Hayes
- Hansard - - - Excerpts

I always listen to you, Madam Deputy Speaker, and to the hon. Member for Hinckley and Bosworth (Dr Evans). As I said at the outset, I support all of what was said by my hon. Friend the Member for Halesowen, who went into great detail about the amendments. The point I am bringing us back to is that Conservative Members need to put country before petty party politics. They are acting in a childish way and they are overexcited about this debate. This treaty protects our national interest. It safeguards British interests. The Opposition have a cheek, when they were responsible for at least 85% of the negotiations that led to this debate.

I will close with this. In this House, we speak through the Chair, because doing so tempers debate. When I speak with schoolchildren about the House, they remark upon the fact that we are in an old building, and that shows our continuity over many years of history. In this place, we make decisions in a sombre, sober way. We do not make them in the same way as the President of the United States did last night, in the form of a rash tweet. Let us not take that social media post at face value. Let us do the reasonable thing and debate this matter properly.

Time is tight, and interventions should be taken with caution. I call Sir John Hayes.

John Hayes Portrait Sir John Hayes
- Hansard - - - Excerpts

I am immensely grateful, Madam Deputy Speaker. The best laws begin as Bills that metamorphosise during their passage and are improved through scrutiny. However, that depends on Ministers listening and learning. The amendments before us from the House of Lords are measured and reasonable. They are not wrecking amendments, but attempts to save the Government from their worst instincts. They provide greater scrutiny, greater parliamentary oversight and more checks and balances, yet they are rejected by the Government.

I will not speak, in the brief time available, about the cost of the deal, although it is wholly unpalatable that we should give away a treasured possession and then rent it back from a foreign place. I will not speak about the strategic cost of doing just that, although I will draw on Lord West’s remarks. That former Labour security Minister, who sits on the Intelligence and Security Committee with me, said:

“surrendering sovereignty over the Chagos Islands would be an irresponsible act, which would put our strategic interests—and the interests of our closest allies—in danger.”

That is wholly unwise.

I will speak, however, about the interests of the Chagossians, who have been ignored throughout this process, who were uninvolved in the negotiations from the outset, whose voice has not been heard, and whose future has been disregarded. That seems to me to be wholly unethical.

This is unwise, unpalatable, unwelcome, unethical, and fundamentally wrong. The Lords amendments would make some improvement to something that is woeful. I implore the Government to accept the amendments. More than that, I implore them to abandon this sorry mission, which is not in the national interest, and certainly not in the interests of the Chagos islanders.

For the final Back-Bench contribution, I call Andrew Rosindell.

Andrew Rosindell Portrait Andrew Rosindell (Romford) (Reform)
- Hansard - - - Excerpts

This has been fundamental to everything I have ever stood for in this House as a Member of Parliament. This Bill did not have its origins in this Government; these were originally the proposals of the previous Conservative Government. No Government have ever given the right of self-determination to the Chagossian people. Shamefully, we have treated them differently from all the other overseas territories. We sent a taskforce to rescue the Falkland Islands. Margaret Thatcher would never have given one inch of British territory away to a foreign country, let alone have paid billions of pounds to do so. This is a shameful day for our country. We are giving away the King’s islands. Rescuing the Falkland Islands was the right thing to do; betraying the Chagossian people is absolutely the wrong thing to do.

My former party went along with this for years, ignoring everything I ever said to every Foreign Minister and every Foreign Secretary. Over and over again, I raised this issue, and warned that it would lead to this catastrophe. I was ignored, and now we see the betrayal of the Chagossian people, our national security is being threatened, and we are paying billions for it. I say to all colleagues on both sides of this House—including those in my new party, but particularly those in my old party —that this is a humiliation for this country, and a betrayal of the loyal British people sitting in the Gallery today who should have the right of self-determination. I am ashamed of what this Parliament is voting on today. I will speak up for the rights, democracy and self-determination of all the British people in all the overseas territories.

With the leave of the House, I will close the debate. Hon. and right hon. Members have raised important questions and points during the debate. Once again, I must reiterate that for those who engage in genuine and constructive debate, the Government are willing to find compromise where that is reasonable and proper, and that debate is welcome, as it has been in the other place.

The deal sits at the cornerstone of the defence and security of both the United Kingdom and the United States. It plays a crucial role in defending our interests, our countries and our people and ensures that we remain equipped to face an increasingly complex and dangerous world.

I have to challenge one of the points that has been made repeatedly and falsely throughout the debate. We have heard the same nonsense that this deal puts the base at threat from Chinese interference. [Interruption.]

Nusrat Ghani Portrait Madam Deputy Speaker

Order. There appear to be many side conversations taking place. If Members wish to leave the Chamber, they can do so. Otherwise, we should focus on what the Minister is saying.

I fear the Minister may have inadvertently misled the House. The only public statement by the Chinese Government on this subject was on 29 May last year when they welcomed the Chagos deal.

That is not a point of order. Can we prevent the debate from continuing in points of order? If colleagues wish to intervene, they can try to do so, and it is up to the Minister whether he wishes to respond to those interventions. We can keep going until 7.18 pm when the time will cut off.

Stephen Doughty Portrait Stephen Doughty
- Hansard - - - Excerpts

I was referring to an article published on 14 January by the Chinese ambassador to Mauritius.

The former Government had access to the same legal advice, the same security briefings and the same threat assessments as we do now, including on threats to the operations of this crucial base, and senior figures raised no objections in Parliament, filed no critical questions and voiced no concerns on social media. It is only after leaving government that they have done so. That is not principled opposition; it is opportunistic.

Many questions were raised about the finances. I must be clear that the higher figure of £34.7 billion that was released by the Government Actuary’s Department was a nominal amount and was not adjusted for inflation or the social time preference rate, so it is deeply misleading to cite that figure, given the changing value of money over time. A pound today is not worth the same as a pound tomorrow. Quite frankly, I am baffled at hearing these complaints about the finances, given the billions that the Conservatives wasted on defective personal protective equipment, the festival of Brexit and who knows what else.

There were some very sensible and I think legitimate questions raised about the costs. The Government have always sought to be transparent on these matters. We set out the forecasts at the time of publication, and the documents that we published at the time of the treaty set out that the net present value of the treaty was £3.4 billion, calculated using the Green Book methodology —I have set that out on many occasions before. Of course, I would expect forecasts to change over time, given the changes in the OBR’s forecast inflation rate and other matters. We were transparent then, and of course we will continue that transparency in the usual ways before the House. Indeed, the TaxPayers’ Alliance, no less, has confirmed that the use of a discount rate to give NPV is a standard concept in finance, and that it is reasonable for the Government to use an inflation assumption and a discounting rate to give an NPV of the cost. If we use its suggestion of 2.9%, the annual payments would be £96 million on average, which is £5 million less in today’s money than the Government’s forecast at the time of the treaty’s publication.

Lords amendment 1 disagreed to.

As the House was informed earlier, Mr Speaker is satisfied that Lords amendments 2 and 3 would impose a charge on public revenue that has not been authorised by a money resolution in this House. In accordance with paragraph (3) of Standing Order No. 78, Lords amendments 2 and 3 are therefore deemed to be disagreed to.
