Speaking in the House of Lords on 11 November 2025

Debate

Diego Garcia Military Base and British Indian Ocean Territory Bill

Contribution

My Lords, we had a vigorous debate on the Bill at Second Reading last week, and I thank each and every noble Lord who participated in that debate. I understand and respect the concerns that have been raised, both inside and outside this House. It is worth repeating what I said last week: this Government are committed to supporting—indeed, encouraging—the thorough scrutiny of this Bill throughout its progression. Noble Lords will understand the reason for the delay to the committal Motion last week. The Opposition’s lack of notice to the House regarding their amendment to the Motion made it impractical to proceed. I am pleased that, now the dust has settled, we are able to proceed with the committal Motion as originally planned. I reassure noble Lords that this short interruption will not impact the timing of Committee, which will be on 18 and 25 November. The debate at Second Reading reflected the strength of feeling across the House on this important issue, and I will take this opportunity to address some of those concerns. Last week, we heard the concern across the House that Chagossian perspectives were not sufficiently reflected in the treaty and the Bill. I respect and understand this concern. However, noble Lords will also know that there is a considerable diversity of opinion across Chagossian communities. To inform further debate on this matter, and to demonstrate the Government’s commitment to the Chagossian community, the Government invite the International Relations and Defence Committee to engage a range of Chagossians to ascertain their views on the implications of the Diego Garcia treaty, and to produce a report. This process will not hold up the passage of the Bill but will be a welcome addition to debate in the House. It will be for the committee to determine the timing of the report, and I extend my thanks to the noble Lord, Lord De Mauley, who has agreed in principle to undertake this work. I also welcome the challenge we heard to increase the participation of Chagossians in political processes. Noble Lords will know that the Government have established a Chagossian contact group to provide Chagossians with a formal role in decision-making on the UK Government’s support for their community. Following last week’s debate, the Government will explore opportunities to enhance that group by increasing its transparency and frequency. We are clear, however, that any decisions about the contact group must be made in agreement with its existing members. The Government will engage the group on this question shortly. Further concerns were raised at Second Reading about the Chagossian trust fund and British Chagossians’ eligibility for resettlement. The Government are committed to making a Statement about both to the House as soon as can be practically achieved. Noble Lords will understand that this should happen only with the agreement of the Mauritian Government, which the Government are urgently pursuing. I welcome the discussion we had on the Bill’s defence and security provisions. I reassure the noble Baroness, Lady Goldie, that I am committed to writing a response to the forensic questions that she asked last week. This response will be sent later this week and a copy will be laid in the Library of the House. Finally, I am aware that noble Lords have a strong interest in the protection of the environment around the Chagos Islands. Last week, I mentioned that the Government have welcomed the announcement of the Mauritian Prime Minister’s Office on 3 November, confirming Mauritian plans for the establishment of a marine protected area after entry into force of the treaty. This protected area will utilise the internationally recognised categories of the International Union for Conservation of Nature. There will be no commercial fishing across the entire 640,000 square kilometre area. The Great Chagos Bank will be given one of the highest levels of protection, with the rest of the MPA categorised as a highly protected conservation zone. Noble Lords will be reassured that there will be limited provision for controlled levels of artisanal fishing in confined zones intended for resettlement to allow for subsistence fishing by any Chagossian communities that resettle, while maintaining the commitment to nature conservation. It is clear that this Bill is fundamental to the operation of the base on Diego Garcia and the protection of national security. The Government have also demonstrated their firm commitment to supporting Chagossians and enhancing environmental protections for the archipelago. I look forward to further debate on these important issues in Committee. I beg to move.
