Diego Garcia Military Base and British Indian Ocean Territory Bill - Committee (1st Day) (Continued) – in the House of Lords at 10:15 pm on 18 November 2025.

14: Clause 1, page 1, line 7, at end insert “, but sections 2 to 4 of this Act do not come into force until the duties outlined in section (Approval in a referendum of the Chagossian people) have been discharged.” Member’s explanatory statementThis Amendment would prevent the provisions from coming into force until the Government has ensured that there has been a referendum of the Chagossian people on the question of sovereignty.
Lord Callanan
Shadow Minister (Foreign, Commonwealth and Development Office)
I thank the noble Lord for his statement, but the Chief Whip’s Office was informed last night of my intention to degroup these amendments. In fact, it wrote to me and to my noble friend Lord Lilley to ask if I agreed with grouping his Amendment with this degrouped amendment. Clearly, there was an expectation from the office that it would do that and then, sometime during the day, that expectation was changed. The noble Lord would have a case if the Chief Whip’s Office had been given no notice whatever and did not know anything about it, but clearly it does. As the Deputy Chairman of Committees indicated, notice has been given and there was an expectation that this would take place.
To go on to the issues in consequence—
Lord Leong
Lord in Waiting (HM Household) (Whip)
I just want to clarify that I have a note here saying that the Chief Whip decided this afternoon. Given how late the change was made, it could not be reflected in Today’s List, which had already been published. I informed the Deputy Chairman of Committees of the degrouping just 10 minutes ago.

Thank you. I think the noble Lord has just confirmed that the Chief Whip decided this afternoon, but the Chief Whip’s office was informed last night. If that was the case, why did the Chief Whip’s office email my noble friend Lord Lilley and me this morning asking whether we were in agreement with his Amendment being incorporated in my degrouping? Clearly, there was an expectation that that would happen. The Chief Whip decided this afternoon that he did not want to do that, and it is his right to do that. But, as the noble Lord, Lord Leong, has also acknowledged, it is my right on the Floor of the House to degroup the amendment, which is what I am doing. It seems to me to be a bit of a silly and pointless debate.
I am tempted to quote the late Lady Thatcher in a discussion on referendums, when she argued that they are a practice to be referred to only on constitutional issues. I think that still holds as a good rule of thumb. Where there is a chance that a model of governance is fundamentally altered, politicians may take a direct democratic approach. Despite our reservations, the Chagos Archipelago is about to undergo the most foundational change in its terms of governance. We are giving away sovereignty over the islands in what is another step in a long story of Britain, sadly, failing the Chagossians, the vast Majority of whom in a survey released today do not want Mauritius to be in control of their sovereignty. We would not cede sovereignty over a part of these islands to another state without consultation, and it is unlikely that it would happen without a referendum. So why does this principle not hold for the Chagossians? That is the question we are putting to the Government with these amendments.
I am sure that the Government have not applied different principles to different peoples out of pure negligence. The reason the Government will not agree to a referendum on this trajectory-altering decision is because, at heart, they know that this is a dud deal. The Government know they are selling the Chagossian people down the river, all to continue their policy of blind adherence to the opinions of the Attorney-General and international lawyers. They know that they have not taken the necessary steps to ensure that this is what is best for both the British and Chagossian populations. They know that, if given the choice, the Chagossian people would almost certainly choose for the archipelago to remain British.
A poll conducted by the Friends of the British Overseas Territories and endorsed by Whitestone Insight found that 99% of the 3,389 Chagossians who responded to the poll were in favour of the archipelago remaining British. It is simple: the Chagossian community overwhelmingly opposes this Bill, and that is why the Government have not consulted it properly—because they do not want to receive an answer that they do not like. That is why the Government will also, I suspect, resist a referendum on the Chagossians.
It is also puzzling that other noble Lords—sadly, not many of them are in the Chamber at this late hour—have not tabled their own amendments on a referendum. Certain members of the Foreign Office contingent that normally sits over there were in favour of two referendums on our EU membership, but it seems that they are not in favour of even a single one for the Chagossians.
The Liberal Democrats’ foreign affairs spokesman, Al Pinkerton, was very clear on his party’s support for a referendum. He said that the Liberal Democrats stood for Chagossian sovereignty over their own citizenship and protection of their rights. He said that
“this Bill fails the Chagossian people” because it continues the injustice of taking decisions about the Chagos Islands
“without the consent of those most affected”.
The referendums that we are proposing would actually ask for the consent of those most affected. This was, he said, to be remedied through
“a referendum of the Chagossian people themselves
I was sad to see that there was no Liberal Democrat amendment on a referendum. That prompted me to put my amendments down for debate, and I am grateful to my noble friend Lord Lilley for also tabling his own amendments.

I am grateful to the noble Lord for giving way. He absolutely put his Amendment down. At first, I thought I would do him the courtesy of listening to how effective he was going to be in making his argument. So far, I am finding out that, the more briefly he speaks, the more persuasive he is.
Lord Callanan
Shadow Minister (Foreign, Commonwealth and Development Office)
It is not my fault if the Liberal Democrats do not want to be consistent on this.
The point is that colleagues of the noble Lords to my left have argued in the other place for a referendum, but the Liberal Democrats in your Lordships’ House have done nothing. The noble Lord has tabled just two amendments, only one of which is consequential. When we debated ratification, the noble Lord, Lord Purvis, withdrew his amendments to the Motion without a Division. I think that speaks a thousand volumes. It seems that it falls to my noble friends on these Benches to stand up for the Chagossians and ask for the referendum that they rightly deserve. I beg to move.
Lord Lilley
Conservative
I support my noble friend Lord Callanan’s Amendment. My own amendment also calls for a referendum. The Government have given priority to the Mauritians—and, indeed, to some extent, the advisory opinion of the International Court of Justice—maintaining what they think of as territorial integrity over the right to self-determination. That should not be the case. Under international law, the right of a group within a decolonised area to self-determination has priority over so-called territorial integrity. It is very regrettable that that has not yet been conceded.
When we come to vote on this subject on Report, as no doubt we will, I very much hope that this will be an area where there is widespread support across the House. I very much hope that the Liberal Democrats will support a vote requiring a referendum among the Chagossian people over the right to self-determination. We are told that they did so in the Commons. In fact, they were so moved by it and thought it such an important issue that they voted against the whole Bill at Third Reading.
So far, the amendments the Liberal Democrats have tabled cannot be said to be amendments that would require a referendum. Amendment 80, tabled by the noble Lord, Lord Purvis, would require that
“a Minister of the Crown must engage with the Government of the Republic of Mauritius with a view to establishing a Joint Parliamentary Commission”.
We are getting “could”, “may” and “might” added together.
Lord Lilley
Conservative
I will speak to the noble Lord’s Amendment first, because I am informing the House about it, and then he can tell me where I am wrong.
Amendment 80 would require that, having engaged with the Mauritian authorities to set up this joint commission, and having perhaps persuaded them to do so:
“The Minister of the Crown must further propose that the Commission’s responsibilities include … evaluating the recognition and protection of Chagossian rights, including … the right of return” and
“the right to self-determination”.
We would therefore have to seek the Mauritians’ agreement on setting up a commission and then propose to that commission that it does something to evaluate the recognition and protection of Chagossian rights, which would include the right of return and to self-determination. However, this amendment, if we were to accept it, contains absolutely no requirement for the House to support a referendum. Indeed, it is extremely unlikely that this convoluted chain of events would lead to such a recommendation.
The final sentence of the amendment reads:
“If the Commission described in subsection (1) is established, within five years of the commencement of the Treaty”,
et cetera. The commission is not envisioned to even get going for several years, and the amendment is probably realistic to recognise this. I am looking forward to a serious Liberal amendment, or their support for serious amendments from me and my noble friend that would require a referendum. I give way to the noble Lord, now that he knows more about what his amendment says.
Lord Purvis of Tweed
Liberal Democrat Lords Spokesperson (International Trade), Liberal Democrat Lords Spokesperson (International Development), Liberal Democrat Lords Spokesperson (Foreign and Commonwealth Affairs), Liberal Democrat Leader in the House of Lords
I first apologise to the noble Lord, Lord Callanan, for intervening when he was moving his Amendment. I am flattered by being so courted by the noble Lords, Lord Callanan and Lord Lilley. Historians will be aware that the Rough Wooing was not entirely successful in my Border area. I have a question for the noble Lord, Lord Lilley, that I am sure he will be able to clarify. He is aware that the House of Commons voted on Amendment 9 for a referendum. Tabled by my colleagues, it would have required the Government to seek to
“undertake negotiations with Mauritius on a Chagossian right of return and on a referendum” for Chagossians on self-determination. Parliament has voted on this already. The Division was 319 votes against and 83 in favour. The Conservatives did not support it. Why?
Lord Lilley
Conservative
I am afraid I cannot tell the noble Lord that. I read the debate and it was not clear that there was much focus on the Liberal Amendment. He has read out part of it; it covered lots of other things and they probably thought it was a bit wishy-washy.
Lord Purvis of Tweed
Liberal Democrat Lords Spokesperson (International Trade), Liberal Democrat Lords Spokesperson (International Development), Liberal Democrat Lords Spokesperson (Foreign and Commonwealth Affairs), Liberal Democrat Leader in the House of Lords
I do not think that is quite acceptable. Amendment 9 was voted on, and it included everything that the noble Lord asked of me. Why did the Conservatives not support it?
Lord Lilley
Conservative
I do not know. I am not an official representative of the Conservative Party. I am flattered that the noble Lord thinks I control the Conservative Party in the Commons and in this place. I do not do either. I have not had any ministerial role since about 2000. I may give the impression of having power and influence beyond that which I really do, and I am flattered that he should think so.
I would like to see the Liberal Democrats support us. We know that, if they do, we will win, but they seem unlikely to do so. It is clear that they have done a deal with the Government. They will never defeat the Government on issues of substance because, if they do, they will not get as many peerages as they want next time. Let us be quite clear about this. It is as shoddy as that underneath this, I suspect. I hope I am wrong—I may well be. I often am.
It would be a wonderful thing, and we may be able to achieve something for the Chagossians in the shape of getting an Amendment on Report—not now, because we are in Committee—which has the support of a Majority in this House. If we carry it out, the odds are that the Chagossian people will declare that they do not want to be incorporated in Mauritius and would prefer to remain citizens of the British Indian Ocean Territory and British subjects. In that case, we should honour and support their decision when it is taken. I look forward to a Damascene conversion by the Liberal party to this amendment.

My Lords, we are almost having another debate on the referendum, which I spoke to on the original Amendment from the noble Lord, Lord Callanan, earlier. The referendum is probably one of the most important aspects of the Bill, because it is fair and needed and the Chagossians really want it. I am not really interested in what the noble Lord, Lord Purvis, said about what happened on the amendment on a referendum in the other place, because it was not in the manifesto. As far as I am concerned, we in this Committee should be able to make up our own minds and should certainly not be stopped from moving amendments to the Bill just because the other place has decided something.
It is so just so antidemocratic. I am amazed that the Labour Back-Benchers are going along with this. They are not here—does that mean that they do not actually support the Bill but are having to be loyal? It is a shocking Bill. As the noble Lord said at the beginning, and as the noble Baroness, Lady Goldie, said at Second Reading, this must rate as the worst Bill that Labour have brought forward—which is quite difficult, as there have been so many awful Bills. They just cannot justify it.
These amendments tonight are very important, and I hope that, when we come back on Report, many more Members will have actually read what has gone on in this debate and recognised that to support a referendum is the right thing to do.

I thank noble Lords for their comments on this. I feel that we have discussed the issue of a referendum fairly comprehensively, as the noble Baroness suggested.
The noble Lord, Lord Lilley, pointed the finger at the Lib Dems and accused them of inconsistency. I do not always see eye to eye with the noble Lord, Lord Purvis, nor with the Liberal Democrats, but if you want consistency on this issue, I do not think you could do much better than the noble Lord or his colleague, the noble Baroness, Lady Ludford, who has championed the rights of the Chagossians for very many years. I have frankly never heard a peep out of the noble Lord opposite or from many of his colleagues on this topic, the rights of Chagossians, resettlement or anything else to do with the Chagos Islands. If we are after consistency, then the Liberal Democrats have, to be fair, been pretty consistent on this issue for very many years now.
On the issue of a referendum, I remind the Committee that negotiations on the treaty were between the UK and Mauritius, with our priority being to secure the full operation of the base on Diego Garcia. The Chagos Archipelago has no permanent population nor has ever been self-governing. No question of self-determination for its population can therefore arise. This has been tested in the English courts, as we said in our earlier debate, in a series of judgments since the 1970s. The transfer of sovereignty does not deprive the Chagossians of any existing right.
A time for a referendum or some formal legal basis of a consultation would have been prior to this point, maybe even prior to or during some of the 11 rounds of negotiation undertaken by the previous Government. This is despite the fact that they clearly now think that there is absolutely no legal risk to the security of the islands. It is really important that we do not allow the Chagossian community to have the impression that a consultation or a referendum held now would in any way be able to affect a treaty that has already been agreed by two Governments and that we have been instructed to ratify by votes in both Houses. The Bill has also been through all its processes in the other place.
With that, I hope the noble Lord decides to withdraw his Amendment.
Lord Callanan
Shadow Minister (Foreign, Commonwealth and Development Office)
My Lords, it is now 10.48 pm. There are not many Members remaining in the Chamber. The next group of amendments is very long and relates to a very important issue, so I invite the Government to resume the House at this stage.
Lord Leong
Lord in Waiting (HM Household) (Whip)
My Lords, we are very happy to continue. As I said earlier, the degrouping was done very late. I have been instructed that we have to carry on until the next group.
Baroness Foster of Aghadrumsee
Non-affiliated
I note that, in the supplementary Marshalled List of amendments, the noble Lord, Lord Thurlow, has two amendments which pertain to the environment. It would be much better if those were attached to the next grouping. Therefore, I agree with the noble Lord, Lord Callanan, that this is a good point to adjourn.
Baroness Hoey
Non-affiliated
My Lords, following on from that, these amendments coming up are on really important environmental issues that the government party says it cares about very much. I know that there may well have been some agreement, but we Back-Benchers who are not in any political party do not get asked about our agreements on anything, so I would formally like to propose that this House do now resume.
Lord Purvis of Tweed
Liberal Democrat Lords Spokesperson (International Trade), Liberal Democrat Lords Spokesperson (International Development), Liberal Democrat Lords Spokesperson (Foreign and Commonwealth Affairs), Liberal Democrat Leader in the House of Lords
My Lords, degrouping after groups have been published goes against what is clearly in the Companion. It is to be discouraged, as a consequence of the Procedure Committee clearly outlining in 2022 why it is, in effect, a discourtesy to the House. This has happened. Sometimes there are consequences to these discourtesies, which is why the Companion indicates that they should be discouraged, and that is when colleagues are under the understanding that reaching certain target groups will be adhered to. It is up to all colleagues to offer due respect to other colleagues who take part in these groupings, but I have been watching the clock on a number of occasions when colleagues have gone far beyond what is considered a courtesy to the Committee in the Companion. There are consequences to how we conduct our debates; one is that we should adhere to our understanding and consider the next group.
Baroness Hoey
Non-affiliated
My Lords, I actually move that this House do now resume.
Viscount Stansgate
Deputy Chairman of Committees, Deputy Speaker (Lords)
The noble Baroness has moved that the House do now resume. I will take advice as to whether it is debateable. It is debateable, in which case the Motion now stands before the Committee.
Baroness Chapman of Darlington
Minister of State (Development)
I wish to oppose the noble Baroness in the suggestion, because I think we have made some good progress this evening and had some good debates. We are about to discuss some very important issues around the marine protected area. I am here and ready to do that, despite the bizarre late degrouping for no apparent reason, when we had a repeat of an earlier debate. I think it would be good to make some progress this evening.
Baroness Foster of Aghadrumsee
Non-affiliated
I imagine that the noble Lord, Lord Thurlow, would want his two amendments grouped with the other marine protected area amendments. Unfortunately, he is not here. It would be good to have all those amendments grouped together, so that we could have a thorough exposition of the environment, instead of part of it tonight and part of it next Tuesday. I would have preferred it if my Amendment 20A was grouped with the right of Chagossians to return, which was already debated but, because it was not, it now has to wait until next week. So I think there is an argument to have the next group next week, so that all the marine environment amendments can be heard together.
Viscount Stansgate
Deputy Chairman of Committees, Deputy Speaker (Lords)
My Lords, the Question has been put that the House do now resume. I must now put that Question. I think on a show of voices the Not-Contents have it.
Baroness Hoey
Non-affiliated
My Lords, would it be helpful if I move that the House do now adjourn?
Baroness Foster of Aghadrumsee
Non-affiliated
Obviously, we are not going to have a vote now, but it would be helpful for those of us who are non-aligned in this House to have more communication than we have had to date in relation to these matters. There seem to be quite a few of us.
Lord Purvis of Tweed
Liberal Democrat Lords Spokesperson (International Trade), Liberal Democrat Lords Spokesperson (International Development), Liberal Democrat Lords Spokesperson (Foreign and Commonwealth Affairs), Liberal Democrat Leader in the House of Lords
Perhaps I might say to the noble Baroness that communication with regard to the degrouping was not equally applied to all, so I have sympathy with her. Perhaps if we continue with this group now, we might conclude this evening in an amicable way.
As a bill passes through Parliament, MPs and peers may suggest amendments - or changes - which they believe will improve the quality of the legislation.
Many hundreds of amendments are proposed by members to major bills as they pass through committee stage, report stage and third reading in both Houses of Parliament.
In the end only a handful of amendments will be incorporated into any bill.
The Speaker - or the chairman in the case of standing committees - has the power to select which amendments should be debated.

A parliamentary bill is divided into sections called clauses.
Printed in the margin next to each clause is a brief explanatory `side-note' giving details of what the effect of the clause will be.
During the committee stage of a bill, MPs examine these clauses in detail and may introduce new clauses of their own or table amendments to the existing clauses.
When a bill becomes an Act of Parliament, clauses become known as sections.
The government chief whip, whose official title is parliamentary secretary to the Treasury, is appointed by the prime minister and is responsible to him.
The chief whip has to maintain party discipline and to try to ensure that members of the party vote with the government in important debates.
Along with the other party whips he or she looks after the day-to-day management of the government's business in Parliament.
The chief whip is a member of the Cabinet.
It is customary for both the government and the opposition chief whips not to take part in parliamentary debates.
The chief whip's official residence is Number 12 Downing Street.
The term "majority" is used in two ways in Parliament. Firstly a Government cannot operate effectively unless it can command a majority in the House of Commons - a majority means winning more than 50% of the votes in a division. Should a Government fail to hold the confidence of the House, it has to hold a General Election. Secondly the term can also be used in an election, where it refers to the margin which the candidate with the most votes has over the candidate coming second. To win a seat a candidate need only have a majority of 1.
The House of Lords. When used in the House of Lords, this phrase refers to the House of Commons.
The House of Commons votes by dividing. Those voting Aye (yes) to any proposition walk through the division lobby to the right of the Speaker and those voting no through the lobby to the left. In each of the lobbies there are desks occupied by Clerks who tick Members' names off division lists as they pass through. Then at the exit doors the Members are counted by two Members acting as tellers. The Speaker calls for a vote by announcing "Clear the Lobbies". In the House of Lords "Clear the Bar" is called. Division Bells ring throughout the building and the police direct all Strangers to leave the vicinity of the Members’ Lobby. They also walk through the public rooms of the House shouting "division". MPs have eight minutes to get to the Division Lobby before the doors are closed. Members make their way to the Chamber, where Whips are on hand to remind the uncertain which way, if any, their party is voting. Meanwhile the Clerks who will take the names of those voting have taken their place at the high tables with the alphabetical lists of MPs' names on which ticks are made to record the vote. When the tellers are ready the counting process begins - the recording of names by the Clerk and the counting of heads by the tellers. When both lobbies have been counted and the figures entered on a card this is given to the Speaker who reads the figures and announces "So the Ayes [or Noes] have it". In the House of Lords the process is the same except that the Lobbies are called the Contents Lobby and the Not Contents Lobby. Unlike many other legislatures, the House of Commons and the House of Lords have not adopted a mechanical or electronic means of voting. This was considered in 1998 but rejected. Divisions rarely take less than ten minutes and those where most Members are voting usually take about fifteen. Further information can be obtained from factsheet P9 at the UK Parliament site.
Ministers make up the Government and almost all are members of the House of Lords or the House of Commons. There are three main types of Minister. Departmental Ministers are in charge of Government Departments. The Government is divided into different Departments which have responsibilities for different areas. For example the Treasury is in charge of Government spending. Departmental Ministers in the Cabinet are generally called 'Secretary of State' but some have special titles such as Chancellor of the Exchequer. Ministers of State and Junior Ministers assist the ministers in charge of the department. They normally have responsibility for a particular area within the department and are sometimes given a title that reflects this - for example Minister of Transport.

The House of Commons is one of the houses of parliament. Here, elected MPs (elected by the "commons", i.e. the people) debate. In modern times, nearly all power resides in this house. In the commons are 650 MPs, as well as a speaker and three deputy speakers.
The Conservatives are a centre-right political party in the UK, founded in the 1830s. They are also known as the Tory party.
With a lower-case ‘c’, ‘conservative’ is an adjective which implies a dislike of change, and a preference for traditional values.

The Second Reading is the most important stage for a Bill. It is when the main purpose of a Bill is discussed and voted on. If the Bill passes it moves on to the Committee Stage. Further information can be obtained from factsheet L1 on the UK Parliament website.
