Diego Garcia Military Base and British Indian Ocean Territory Bill

Baroness Meyer Excerpts

Committee stage
Tuesday 18th November 2025 Lords Chamber

[Lord McCrea of Magherafelt and Cookstown (DUP)]

I am coming to a conclusion. I understand what it is like to feel ignored and sidelined; to have someone in Government tell you that your identity is second class; that you cannot really be a full British citizen. I know what it is like to have fought for your rights to represent your people when a foreign state wades in against you. I understand the struggle to be heard more than most. Parliament therefore has a responsibility to correct that course. These amendments do not ask for much.

[Baroness Meyer (Con)]

My Lords, I shall speak in support of Amendments 14 and 25. This treaty and the Bill that will enact it is bad for our country, for our security and for British taxpayers. As we have already discussed, it will leave Britain poorer, weaker and strategically exposed.

This treaty is also bad for the Chagossian people. Half a century ago, they suffered the terrible injustice of forced removal. This treaty compounds that injustice by offering no guaranteed right of return, no legally binding resettlement plan and no meaningful protection of their rights. This is truly shameful. For a Government who claim to uphold human rights, it is an extraordinary moral failure.

Dr Al Pinkerton, the Liberal Democrat spokesman, said at Third Reading in the House of Commons that

“we cannot allow the Bill to pass without ensuring that Chagossians themselves are sovereign over their citizenship, the governance of their islands and the prospect of return”.—[Official Report, Commons, 20/10/25; col. 756.]

He is right, and I am surprised that no Liberal Democrat in this House has put down any amendment in support of a referendum. To deny the Chagossians their right of self-determination and to shape the future of their homeland is unworthy of a country that champions justice, fairness and democracy. This amendment would give them a chance, but it would also give us, a nation that prides itself on a centuries-old democratic—

[Lord Purvis of Tweed (LD)]

I am grateful to the noble Baroness. I make the assumption that, in her defence, she did not read my amendment before making her statement, because the right to self-determination is there under proposed new subsection (3)(b)(ii). Can she clarify what her referendum would be? Would it include the sovereignty, the possession and the inhabitation of the military base on Diego Garcia?

[Baroness Meyer (Con)]

I presume that a referendum would actually ask the Chagossian people what they want for their future and self-determination.

[Lord Purvis of Tweed (LD)]

To clarify: it is the position of the Opposition that the referendum would also be for there to able to be inhabitants on the military base?

[Baroness Meyer (Con)]

But I allow my noble friend.

[Lord Hannan of Kingsclere (Con)]

The Chagossian people have made it very clear what they want. They had their own opinion poll on the subject, and that has been independently verified: 99.22% of people voted for it. The noble Lord, Lord Purvis of Tweed, asked what the proposition would be. It is for a resettlement on the outer atolls, under British jurisdiction and as British overseas citizens, in accordance with the plan set out in 2015, to which the noble Baroness, Lady Foster, referred earlier.

[Baroness Meyer (Con)]

Yes, and they seem to approve what we are saying. Basically, these amendments are about asking the Chagossian people about the right to self-determination through a referendum. I have never met a Chagossian in my life, but I have received many letters from them over the past few days and feel that this is my moral duty, and I think that, in good conscience, the Government should allow them self-determination.

[Baroness Hoey (Non-Afl)]

My Lords, I support all the amendments in this group, but I particularly like Amendment 64, because it goes to the heart of the issue and is very simple and straightforward: we want a referendum. I think the noble Lord, Lord Hannan, answered the noble Lord on the Front Bench who asked about what a referendum would mean; I concur exactly with that, and I hope that that has satisfied him.

When we are trying to get an argument for providing the people of the Chagos Islands with self-determination, sometimes it is useful to consider the arguments being put against it. There are two key arguments that the Government seem to deploy for backing the Mauritius treaty and the Bill, rather than a self-determination referendum, the provision of which would be not necessarily easy but technically possible and would include all the Chagossians not just in the UK but around the world.

The Government’s first argument would seem to be that we are excused from the need to provide the Chagossians with self-determination because we removed them from the Chagos Islands and so they can no longer be offered self-determination. So long as the Government say that it was very wrong that the Chagossians were removed, the Government seem to think that the fact that they no longer live on their islands relieves us of the moral obligation to provide them with self-determination on their future. For me, this constitutes a pretty appalling logic that lays bare not only the complete moral failure of the current Government but the deployment of a rather dreadful logic in a way that I believe really lets down the people of our country, the United Kingdom, in a very humiliating fashion.

The Chagossians themselves call this out in a very powerful statement on self-determination, which I am sure the Minister will have read, that they issued yesterday. I am going to quote from it, because I think it is really important. They say:

“In recent years there has been much repenting of colonialism within certain parts of the West, including the United Kingdom. The problem with colonialism is one of alienation. In its conventional form it is problematic because it alienates a people from the dignity of self-government of their home territory, but not from that territory. They can continue to live on the territory that is their home and nurture the hope that at some point they might be afforded the dignity of self-government. The colonialism to which we have been subjected, however, presented a far more extreme and unusual alienation because it alienated us not just from the dignity of a measure of self-government but far more problematically, from our territory, our home, by taking it from us.


If the international community is serious in its commitment to decolonise then it cannot afford to accommodate either alienation. To do so, however, in the context of re-denying”—


I emphasise this—

“the people concerned self-determination while simultaneously paying a country that played a key role in denying that people self-determination in relation to their territory on the previous occasion, more money than is required to resettle the people with the rightful claim to the territory, in order to lease one of their islands, demonstrates extreme moral disorientation.

In this context the policy of the current Government to state that what happened between 1968 and 1973 was deeply wrong but then not lift a finger to put that right, even as they demonstrate that the resources are more than available to do so, not only makes the condemnation of what happened between 1968 and 1973 completely hollow, but also necessarily has the effect of affirming the validity of what happened”.


I think every noble Lord should read that statement carefully; there is more in it.

If we put this another way, attempts by His Majesty’s Government to claim that the United Kingdom is relieved of any obligation to provide the people of the Chagos Islands self-determination in relation to their islands because they are not living there is just another way of saying that we are relieved of the responsibility for having prosecuted the most extreme form of colonialisation because we prosecuted the most extreme form of colonialisation. I think it is plain for all to see that, if we are justifying ourselves in not providing self-determination to the Chagossians—which we would do by at least asking people in a referendum—because we removed them from their islands, we are suggesting that removing them from their islands validates this, as if the crime of their forced removal constitutes a source of validity. Rather than providing a source of validity for not providing self-determination to the people of the Chagos Islands, I believe that this logic lays bare the complete moral failure of the current Government and the way in which it shames us as a nation.

The other argument that the Government provide against affording the Chagossians a self-determination referendum is implicit in their references to Chagossians who support the Mauritius treaty, as if the Chagossians supporting it means that providing the Chagossians self- determination is unnecessary because we already know what they want. I do not doubt that there are some Chagossians, particularly some in Mauritius, who support the Mauritius treaty. There has never been, in my opinion, a self-determination referendum in which 100% of people voted in one way. However, what is incontrovertible is that we have to engage with the fact that not only do we have some 650 Chagossians who have been involved here in the United Kingdom but the survey of over 3,000 Chagossians living in the UK, Mauritius and the Seychelles demonstrates over 99% opposition to being given away—just think about that—to the Republic of Mauritius and support for self-determination as a resettled British overseas territory such as Anguilla or Montserrat. That is 99%. They do not want to be given away to Mauritius; they want to stay British.
