Diego Garcia Military Base and British Indian Ocean Territory Bill

Debate between Baroness Chapman of Darlington and Lord Morrow

Committee stage
Tuesday 25th November 2025 Lords Chamber

[The Minister of State, Foreign, Commonwealth and Development Office (Baroness Chapman of Darlington) (Lab)]

In relation to Amendment 20J, the House has dedicated at least 15 hours to debating the Government’s rationale for entering this treaty. It has been subject to two reports, by the International Agreements Committee and the International Relations and Defence Committee. Three separate committees—the IAC, the IRDC and the Foreign Affairs Committee—have held evidence sessions and questioned the Minister for the Overseas Territories.

The Government have been consistently clear throughout. The legal case was compelling and there was no credible alternative. A policy of hanging tough, which I assume the noble Lord has in mind, would have been a real gift to our adversaries. As we have stated on numerous occasions, the continued operation of the base was under threat. Courts were already making decisions which undermined our position. If a long-term deal had not been reached, further wide-ranging litigation was likely, with no realistic prospect of the UK successfully defending its legal position on sovereignty in such cases.

Legally binding provisional measures from the courts could have come within weeks, affecting, for example, our ability to patrol the waters around Diego Garcia. Both the IRDC and the IAC recognise that the treaty provides legal certainty for the base. I hope the noble Lord will withdraw his amendment.

[Lord Morrow (DUP)]

My Lords, I thank all those who have spoken in this debate. I have noticed that no one has spoken against the amendment, other than the Minister who brought her explanation and reason. I beg leave to withdraw my amendment.

[Baroness Chapman of Darlington (Lab)]

I suggest that the noble Lord looks at the ways in which marine protected areas are generally enforced. It is not, as he seems to imagine, by patrolling in vessels around the ocean, checking on things. That is not how these things work. But I will gladly send him some information about that.

[Lord Morrow (DUP)]

My Lords, I thank the noble Baroness, Lady Hoey, and the noble Lord, Lord Callanan, for their contributions. Having listened to the Minister, I am wondering whether she will get time to reflect on this debate and on what has been asked and what has been said. Perhaps, if she does, she will write to us and put her reply in the Library, for the availability of every Peer in this House. I beg leave to withdraw my amendment.
