Diego Garcia Military Base and British Indian Ocean Territory Bill

Debate between Al Pinkerton and Graham Stuart

Committee of the whole House
Monday 20th October 2025 Commons Chamber

[Dr Pinkerton]

The maximum possible financial transparency around the treaty arrangements is essential, not least for securing and establishing public trust. I fear that, without those high levels of accountability, public trust would rapidly dissipate. Furthermore, once every financial year, the Secretary of State should present to the House an estimate of the expenditure expected to be incurred in connection with the treaty, including payments or financial commitments to the Government of Mauritius and the cost of maintaining and operating Diego Garcia. If actual payments exceed those estimates, a supplementary estimate must be laid before the House for approval and parliamentary scrutiny. I reassure Conservative colleagues that the Liberal Democrats will support any amendment to the Bill that would increase financial transparency of the treaty.

However, our moral duty extends beyond matters of territory and finance. New clause 12 would require a comprehensive review of the welfare, integration and general needs of Chagossians living in the UK. Many Chagossians here face significant challenges, including housing insecurity, barriers to employment and limited access to public services. The review would assess what support is needed and ensure a full debate in this House and the other place on its findings. That is how we show genuine care for those displaced by the actions of our predecessors in the Chamber and in Whitehall.

Finally, new clause 13 would require the Government within six months to consult with Chagossians residing in the UK and the organisations that represent them on how the Act and the treaty affect their community socially, economically and legally.

[Graham Stuart]

The hon. Gentleman is giving a powerful speech on the Chagossians and marine protected areas, as well as the need for transparency. But it is not just about transparency. What I have not heard from him, on behalf of the Liberal Democrats, is any sense of outrage at the very fact that we are to pay out £35 billion for sovereign British territory on which we have arguably the most important base in the whole Indian ocean.

[Dr Pinkerton]

I am grateful to the right hon. Gentleman for his question. It is precisely in order to cast the strongest possible spotlight on the financial transaction involved that we are asking for financial accountability to be magnified. On his geopolitical point, nobody can question the significant geopolitical importance of the base—it is vital to our national security and to global security. It is essential that it is maintained in British hands, but that must be achieved with the consent of the Chagossians.

The resulting report to be laid before Parliament within 12 months would allow us to evaluate whether the Government’s legislative intent has translated into justice and inclusion in the lives of those who are most directly affected.

These amendments would address critical shortcomings with the Bill. They would embed accountability, environmental protection and a commitment to the right to self-determination within its framework for implementation. I urge Ministers to ensure that the Chagossians are not treated as diplomatic collateral in any future discussions with Mauritius. They are not a footnote to be managed between states; they are a people deserving of justice, agency and dignity.

The Chagossians have waited more than 50 years to go home. The least we can do now is let them decide freely and finally what home means for themselves and ensure that they have the tools they need to exercise their rights. The amendments tabled in my name seek to afford those protections and ensure that those rights are respected.
