Speaking in the House of Lords on 30 June 2025

Debate

UK-Mauritius Agreement on the Chagos Archipelago

Contribution

My Lords, today’s debate is odd for two reasons, and that is the one point on which I think I agree with the introductory remarks of the noble Lord, Lord Callanan. First, had the outcome of last July’s general election been different, it is highly possible that the noble Lord, Lord Callanan, or one of his colleagues would have been standing at the Dispatch Box defending an agreement similar to the one we are debating now. How else can one construe the 11 rounds of negotiations that the Government of which he was a member conducted with the Government of Mauritius before that election following the ruling of the International Court of Justice and the overwhelming vote in the UN General Assembly that the UK should negotiate in this sense? Secondly, the noble Lord, Lord Callanan, put down the wrecking Motion he has introduced calling for the agreement not to be ratified even though neither of the two committees examining the agreement—the International Agreements Committee, of which I have the honour to be a member, and the International Relations and Defence Committee—had even begun to take evidence on the text of the agreement, let alone put such evidence in the public domain. The reports of these two committees are now available to the House and they provide no—I repeat, no—justification for the Motion that the noble Lord has put before us. That surely demonstrates a contempt for the two committees, which is deplorable. Some will say, “Well, that’s just politics”, but it should not be so if the work of our committees is to be taken seriously by the House. Now, that lacuna has been filled and our report and the evidence on which it is based have been published and are available to the House, as is the extremely valuable letter from the International Relations Committee. That it should have become available so late in the day is a matter for profound apology, but given the 21 working days we had to conduct our inquiry of quite a complex agreement, it was inevitable once the Government had already, at an earlier stage, turned down our request for an extension. The committees heard the evidence of three distinguished international lawyers. While this evidence was not unanimous, two out of the three—Philippe Sands and Sir Christopher Greenwood—were very clear that the agreement reached was necessary if the UK was to avoid a legally binding finding at some point in the future in addition to the advisory opinion already rendered by the ICJ. It was also particularly striking that Sir Christopher was so clear that it would be incompatible—I repeat, incompatible—with the policy expressed so frequently at the Dispatch Box by both the outgoing Government and the incoming one that the UK supports the rules-based international order, if the UK should then find it inconvenient to do so on this occasion. For what it is worth, that is my own opinion too. At a time when the rules-based order is under such severe attack, it would be especially damaging if one of its principal supporters were to choose opportunism over principle. None of the evidence we received supported the view that has been expressed that this agreement is in any way analogous with, or undermines the legal basis for, the UK’s sovereignty over Gibraltar, the Falkland Islands and the sovereign base areas of Cyprus. In conclusion, I would urge Members to vote against the Motion tabled by the noble Lord, Lord Callanan, and to take note of the report from the International Relations Committee, which clears the way for ratification of the agreement reported on. That is the course consistent with our national security interests and with our respect for international law. Before concluding, I want to say how sorry I am to be speaking before the noble and learned Baroness, Lady Prentis, as I would have wished to congratulate her on her maiden speech. I am sorry also to be speaking before the noble Lord, Lord Boswell of Aynho. He was my boss on the European Union Committee for many years and a completely outstanding chairman of that committee, for whose work we should all express great gratitude today.
