Lords division · 30 Jun 2025 · No. 1

Agreement between the United Kingdom and the Republic of Mauritius concerning the Chagos Archipelago including Diego Garcia

Lord Callanan moved that this House resolves, in accordance with section 20 of the Constitutional Reform and Governance Act 2010 and in the light of concerns about the cost of the agreement, the absence of any legal requirement to conclude such an agreement, its impact on international security, and the lack of meaningful consultation of the Chagossian people, and recognising the right of Chagossians to be registered as British Overseas Territory citizens under the Nationality and Borders Act 2022, that His Majesty’s Government should not ratify the Agreement between the United Kingdom and the Republic of Mauritius concerning the Chagos Archipelago including Diego Garcia, laid before the House on 22 May.

The party breakdowns are our own analysis of the official voting records (recorded votes only; they do not describe the formal whip). How we work this out.

Peers attend divisions ad hoc, so there is no did-not-vote list. Tellers are counted in the Content and Not Content totals, unlike in the Commons.

Tellers: The Earl of Effingham (Content), Baroness Williams of Trafford (Content), Lord Kennedy of Southwark (Not Content), Baroness Wheeler (Not Content).
