In the absence of the noble Lord, Lord Morrow, I should like to move the Amendment standing in his name. Amendments 3 and 4 are about the rights of Chagossians to bear children in the archipelago and the rights of people born in the archipelago to continued British Overseas Territories citizenship. So as not to detain your Lordships any longer than necessary, I will also speak to my own Amendment 50 in this group, which is about registering married Chagossians as British Indian Ocean Territory citizens.

The Minister has just repeated that she deeply regrets the treatment of Chagossians over the decades, and I believe her. She is obviously sincere and has said that on many previous occasions. In our debate last month, she described it as appalling and morally shameful; she said that they had been badly treated over many decades. So I pose the question: what is adequate restitution for this appalling treatment, which all sides seem to agree is deeply shameful? What would constitute a way of making good a wrong in a way that is understood morally and legally? What we mean by restitution, of course, is restoring something. If you have taken something from someone, restitution means giving it back or compensating them to an equivalent value.

I am afraid that all arguments end up in the same place: the restitution sought by Chagossians for those 60 years was the right to return to the homeland from which they had been plucked and then dumped hundreds, or in some cases thousands, of miles away in strange new lands. I want the Committee to think for a moment about what a return would be like: to imagine the resettlement of the atolls around Diego Garcia, if not of the base itself, with the coconut groves coaxed back into order, their fronds trimmed; children born in the islands being taught by their elders how to husk and split the coconuts; villages on the shore, with their bright roofs rising above the takamaka and banyan trees. Imagine the old churches being reconstituted and the coral stone being used. All of that is what is being sought by our fellow subjects of Chagossian origin, as British Indian Ocean Territory citizens, and it is not available under any alternative plan.

Mauritius recognises a right to settle in the island for Mauritians, under whom it includes Chagossians. But what is being proposed by Mauritius is the dissolution of BIOT citizenship into Mauritian citizenship, equivalent in the Seychelles, and now the equivalent for us. This is something that is unprecedented. I do not think that we have ever done this before. Yes, of course, when we have transferred jurisdiction as a withdrawing colonial power, we have transferred citizenship: you become a Kenyan or whatever it is. But I cannot think of any precedent where you remove somebody’s citizenship and instead give them citizenship of a country to which they feel no loyalty at all. As long as this wrong endures—as long as people feel that they do not have the nationality on their passport that they feel in their hearts—there will not be any stability.

The Minister spoke in the last round about why we should not reopen what was defined by the courts as a final, full and binding settlement. Well, it will not be final. By the way, that is what Mauritius agreed to in 1965, when it was paid to renounce all of its claims; reparations are never fully final. The deprivation of Chagossians of the citizenship that they want, that they want for their children and that past Governments legislated for—we amended the Nationality Act 1981 in 2022 in order precisely to create this status—is not going to result in a full and final settlement. On the contrary, there will be as much rejection of that new dispensation from the people most directly involved as there was recently from the Mauritians of the existing status quo. In fact, I would not be at all surprised if the part of the Chagossian population that rejects the deal constitutes itself as a Government-in-exile and begins to seek recognition. The idea that we are doing all of this in order to settle something quietly so that it all goes away is going to be tested by events—I hope I am wrong about this, but I suspect not. We are going to look back and think, “Why did we not see this coming?”

There is a way of going back to what was our plan as recently as 2015: looking at the places in the archipelago that can be resettled without prejudice to the base, allowing those people then to work in the civilian jobs, which are currently done mainly by Filipinos and Sri Lankans and so on, on Diego Garcia itself. It could be that this whole rap becomes what the Falklands war was to that archipelago: the beginning of an economic renaissance as Britain begins to take an interest in its overseas possession and begins to create active economic opportunities for the people there, whether servicing the military facilities or in fishing or whatever it is. But none of that is going to happen if we simply declare that our Chagossian fellow citizens are really just misguided Mauritians and that they have no more particular right to their ancestral homelands and to the graves of their ancestors than any other Mauritian citizen. It is in your Lordships’ power to put a stop to this and not to ratify this treaty. As our national poet said:

“Prevent it, resist it, let it not be so,

Lest child, child’s children, cry against you woe!”

My Lords, I will speak to my Amendments 45, 46, and 48. Following on from the noble Lord, Lord Hannan, these are measures that would in some way perhaps help to make the Chagossian people feel that we had listened to their genuine concerns. Now, all of us who have been involved with the Chagossians have been seeing a lot of very written and spoken letters and speeches about what they went through, and why these amendments in particular would be something that could move things forward for them. In particular, 95 Chagossians have written who were born on the islands and are here. These are men and women who lived very peaceful, self-sufficient lives on the islands, including Diego Garcia, until the day they were forced on to the ships and told they would never see their homeland again.

It is important that we—for the public out there who perhaps have not grasped the detail of this—just repeat some of the things that they have said and why these amendments might make a slight difference. They all tell the same story. They describe being ordered to leave their homes with only what they could carry. Some recall arriving at the jetty to see their dogs and livestock taken from them and killed before they were pushed on to the ship. Others remember family members separated, possessions thrown into the sea and the moment the islands disappeared over the horizon: as one said, “The day the world went dark”. One native islander, now in her 70s, said, “We left our islands with nothing but our clothes. They took our dogs from us, howling. We were pushed onto the boat and told we would never return. Our children and grandchildren still do not have the documents that say who we really are”. Another said, “They took my home and now they take my identity. My passport says nothing of where I come from. We want to remain British with the right to return to our islands. We do not want to become Mauritian”.

I should add that Chagossians living in Mauritius report that, more recently, Mauritian authorities have already begun to replace their recorded place of birth—changing it to simply “Mauritius”—and in some cases their birth dates. So their birthplace, their identity and their history are being administratively erased.

Amendment 45 is on passports and official documentation. Chagossians have lived for a long time without anything that really recognises their origins, because their birthplace was depopulated, renamed and reclassified: in administrative terms, their existence as a people was largely erased. This amendment ensures that Chagossians can hold passports and documents affirming their historic identity and their connection to the Chagos Archipelago and the British Indian Ocean Territory. That identity, let us not forget, was never surrendered voluntarily. It was severed by force. As another Chagossian said, “We want the papers that say who we are. We are Chagossians from the Chagos. That must not be erased”. Yet under Clauses 2 to 4, if they are passed unamended, the United Kingdom would relinquish sovereignty over every island except Diego Garcia, and the legal foundation for recognising Chagossian identity through official documentation would disappear. This amendment helps with that.

Amendment 46 is about citizenship rights for children. Exile produced a citizenship gap that now affects three generations. Had the Chagossians remained on their islands, their children would automatically hold British Overseas Territory citizenship today. But exile broke that line, leaving many Chagossian families undocumented or semi-stateless for decades. This amendment would restore what displacement interrupted: automatic BOTC and BIOT citizenship for children born in the United Kingdom to Chagossian parents. As another native Chagossian wrote, “My children were born here but they do not have the citizenship I would have given them if I had been allowed to live in my home. This is injustice continuing to the next generation”.

Amendment 48 is on the retention of BOTC passports. Many Chagossians still hold a BOTC passport showing that they have a connection to the British Indian Ocean Territory. These are probably among their most treasured possessions because, for many, they are the only official recognition that they belong to those islands. If BIOT is dissolved for all islands except Diego Garcia, these passports will not be renewable and Chagossian identity will disappear again on paper. Ms Colin, one of the Chagossians, wrote, “Do not take our passports from us again. We lost our homes. Must we also lose our true identity?” This amendment would prevent that second erasure.

The legal position is even more troubling, although I have gone on a great deal about the moral one, which I think is hugely important. Nothing in the treaty with Mauritius, international law or the British Nationality Act requires these nationality rights to be removed. The Government are removing them by choice, not necessity. In Section 17H of the British Nationality Act 1981, inserted in 2022, a person with a Chagossian ancestor has the right to be registered as a BOTC and therefore as a British citizen. The connection that matters in law is historic, whether the ancestor was born in the British Indian Ocean Territory or the islands designated as BIOT in 1965. Whether BIOT exists today is irrelevant. Its abolition does not legally require the abolition of Chagossian nationality rights. Only repealing Section 17H does that, and this Bill repeals it.

This has never happened before. There is no precedent in British nationality law for stripping a people of British nationality status when their territory is transferred. In every previous case, from Kenya in 1963 to Saint Kitts and Nevis in 1983, people lost British territorial citizenship only because they gained a new citizenship of their own independent territory. Chagossians have no such citizenship to inherit. Had the transfer of the islands occurred after the registration window opened in 2022, the handover would have had no impact on Chagossian nationality rights. Their status and their ability to transmit it to their children would have remained intact.

The Government’s justification that BOTC is tied to a continuing connection with a British territory is incompatible with the very reason Section 17H was created. The purpose of that section was historical restitution, recognising that exile unjustly prevented Chagossians passing citizenship to their children. That injustice has not been remedied simply because the territory is being transferred.

The International Court of Justice made it clear in 2019 that the people of a non-self-governing territory must be consulted and that their freely expressed and genuine will must determine their future. That did not happen in 1965, and it is not happening now. Mauritius speaks of completing decolonialisation, yet ignores the fundamental principle of decolonialisation, which is the right of the people of the territory concerned to self-determination. The people of the Chagos Archipelago, the only people ever to live there, have not been consulted. They have not been given a referendum. They have expressed overwhelmingly that they do not wish their identity, their citizenship rights or their homeland to be handed over without their consent. As one native islander, Mr Joseph Elyse, wrote:

“We want to be recognised as a people before it is too late. Every year more of us natives pass away. We want our rights returned while we are still alive”.

These amendments do not seek advantage; they seek restoration. They would not create extraordinary rights; they would correct extraordinary wrongs. They would ensure that a people removed from their territory in circumstances now acknowledged by everyone as unjust is not erased again through the disappearance of its legal status, documentation and citizenship.

Many of the 95 surviving native islanders were children when they were taken from their homes. Some have died without justice. Those who remain ask for something profoundly simple: “Let the world know who we are, let our children have what was taken from us and let us be Chagossians in law as well as memory”. This House should honour that request. I therefore commend Amendments 45, 46 and 48 to the Committee, and urge noble Lords to support them.

I thank my noble friend Lord Hannan of Kingsclere for moving Amendment 3 on behalf of the noble Lord, Lord Morrow. We all hope his family member gets well soon. I also thank the noble Baroness, Lady Hoey, for her very powerful speech.

These amendments all touch on the impact that the Bill will have on the citizenship rights of Chagossians. Clause 4 will limit the rights of those descended from Chagos Islanders to gain British citizenship, in several ways. My amendments in this group also seek to challenge the Government’s approach. It should be noted that settlement in the UK is not what many Chagossians want. Many want to return to the archipelago, and this is something that Ministers have discussed previously. That said, British citizenship should be an option for the Chagossians given the responsibility that I think everybody here believes that we owe them thanks to our historic links and, I am afraid, our record of mistreating their community.

My Amendment 7 would prevent the citizenship provisions coming into effect with the treaty, allowing more time for the Government to consider their approach in domestic law alongside the treaty. It might also allow for greater consultation of the Chagossian community, who are ultimately the people who will be affected by Clause 4. In her reply can the Minister confirm whether the Government have had any conversations with Chagossians about the effect of Clause 4? Can she confirm whether substantive discussions on citizenship rights have been held with the Chagossian contact group, which she claims to have met on a couple of occasions? What was the outcome of those discussions? I would also like to know whether Ministers have made any changes to their plans on citizenship rights as a result of some of the concerns raised by the Chagossian community.

My Amendment 39 probes the limitation of citizenship rights by birth year. Will the Minister please explain why 2027 has been chosen as the cut-off date? What opportunity will there be for the Chagossian community to make a case for its extension, should circumstances require it? Another important issue with any cut-off date for applications is communication. Have Ministers given any consideration to the procedure that should be followed to ensure that eligible Chagossians are contacted about their rights?

I have tabled Amendment 40 to probe the requirement that a person must not have previously held British citizenship to be eligible under the changes made by Clause 4. We can understand why it would not be appropriate for a person who has had their citizenship revoked not to be eligible, but why should a person who has given up their citizenship voluntarily be barred by this clause? I hope the Minister will be able to address these questions.

I thank noble Lords for their speeches. A host of amendments, as we have heard, have been tabled in relation to citizenship rights. Some of them come from a bit of a misunderstanding of what Clause 4 does. I hope that I can explain the detail of what the Bill will mean. If it is not enough, I am very happy to write a letter and put it in the Library, because it is detailed and a little bit complicated. If that would be helpful, that is something I am happy to do. Let me have a go at explaining it all properly this evening and that may suffice.

Clause 4 makes provisions related to British nationality as a consequence of the dissolution of the British Indian Ocean Territory. These provisions are essential to ensure that the existing entitlements the Chagossians have to British citizenship remain unchanged. This clause also amends the British Nationality Act 1981 to reflect that BIOT will no longer be a British Overseas Territory, and as a result no future claims to British Overseas Territory citizenship can be made on the basis of a connection to BIOT.

This will not result in any change to the existing British nationality status that any Chagossian currently holds; this remains protected. Any Chagossian who currently holds British Overseas Territory citizenship retains it. Current routes to British citizenship will also continue to exist with their original expiry dates for application. This clause is vital in order to protect Chagossians’ rights to continue to obtain British citizenship. Seeking to delete the clause would be to play politics with this right.

I turn to the amendments tabled. Amendment 4 is a good example of an amendment that I would gently say is somewhat misconceived in its intent. Chagossians born on the Chagos Archipelago already automatically hold British Overseas Territory citizenship and British citizenship. This amendment would therefore seek to require the Secretary of State to bring forward legislation that would apply to anyone of any nationality born on the Chagos Archipelago once it is no longer a British territory.

The Government are clear that, as BIOT will no longer be an overseas territory, it will no longer be possible to make a new claim for British Overseas Territory citizenship. Instead, the Bill preserves Chagossians’ ability to claim British citizenship. Whether a Chagossian has British Overseas Territory citizenship or not will have no bearing on their ability to claim British citizenship under their bespoke citizenship route.

Amendment 39, tabled by the noble Lord, Lord Callanan —I cannot remember whether he said this was a probing amendment—would remove the existing time limit on the rights of Chagossian descendants to apply for British nationality. The time limit reflected concerns that an open-ended offer could result in an unlimited number of individuals without a close and continuing connection to the UK or to an overseas territory acquiring rights to live in the UK indefinitely.

A five-year period was chosen for adults, in line with previous examples of time-limited schemes in the UK and overseas. This was agreed as a reasonable period to allow Chagossian descendants to decide whether they wish to become British citizens. Those under 18 were also given five years to apply from the point that they become an adult.

This is a generous scheme. It reflects the unique and regrettable situation of Chagossians and was welcomed by many when the previous Government accepted the amendments to the Nationality and Borders Bill in 2022. To be clear, is the noble Lord, Lord Callanan, saying that he does not support his previous Government’s decision-making when it comes to balancing the rights of Chagossians with conventional time limits for citizenship schemes? I think he may have shifted his position; he made a clear statement on that in his contribution, and he is, of course, entitled to do so.

Amendment 40, also tabled by the noble Lord, Lord Callanan, seeks to allow a wider range of former British nationals to reacquire British nationality without applying to the Home Secretary to resume it. This amendment would amend the existing limitation found throughout British nationality law that prevents those who have renounced British nationality regaining it without making an application for resumption at the Home Secretary’s discretion. The current drafting of Clause 4 preserves the status quo across all nationality routes, ensuring that the Home Secretary can consider whether a person should be able to resume their citizenship.

Amendment 41 seeks to ensure that Chagossians can apply for British citizenship indefinitely. The Government believe it is right that British citizenship should be limited to those Chagossians with a close and continuing connection with the United Kingdom, and that normally it should be passed on only to the first generation born outside the UK. Of course, if a Chagossian British citizen lives in the UK, his or her children born here will be British citizens. If children are born overseas to a British citizen by descent, the legislation contains sufficient provisions for a child to be registered where a continuing connection with the United Kingdom is demonstrated.

The time limit in current legislation reflected concerns that an open-ended offer could result in an unlimited number of individuals without a close and continuing connection to the UK or to an overseas territory acquiring unfettered rights to live in the UK indefinitely. Chagossians granted British citizenship under the free registration route protected by the Bill can pass British citizenship on to their children.

Amendment 42 would require the Government to consult on a timescale for Chagossians to apply for British nationality under new Section 4KA. For the reasons mentioned in relation to Amendments 39 and 41, the Government do not deem it desirable to change the current five-year time limit.

Amendment 43 seeks to amend the existing provisions and increase the time that some Chagossians can apply to register as British citizens once they reach the age of 18 from five years to 12 years. We do not think it is necessary to extend this period to apply to those under the age of 18. This would create an imbalance between those who were under the age of 30 when the citizenship route opened and those who were born during the current five-year application period.

Amendment 44 seeks to allow new British Overseas Territory citizens to be created through a connection to BIOT once BIOT is no longer an overseas territory. This would allow Chagossians who hold BOTC to pass on that status for one further generation born outside an overseas territory. This would create an anomaly whereby individuals with no connection to an existing British Overseas Territory could acquire that status.

I appreciate that this is a bit involved and complex, and that noble Lords may wish to come back to some of these issues at later stages, but I think it is helpful to lay it out in a detailed and technical way at this stage. If a letter would be a more helpful format for noble Lords, I will put this into a letter and share it. In light of this, I hope the noble Lord will withdraw his amendment.

Amendment 3 withdrawn.

Amendment 4 not moved.

House resumed. Committee to begin again not before 8.16 pm.

Amendment

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.

Secretary of State

Secretary of State was originally the title given to the two officials who conducted the Royal Correspondence under Elizabeth I. Now it is the title held by some of the more important Government Ministers, for example the Secretary of State for Foreign Affairs.

Clause

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.

Minister

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.
