Lords division · 12 Jan 2026 · No. 1

Diego Garcia Military Base and British Indian Ocean Territory Bill

Lord Callanan moved, as an amendment to the motion that this Bill do now pass, at end to insert “but that this House regrets that the UK-Mauritius Agreement concerning the Chagos Archipelago including Diego Garcia does not secure the long-term future of the Diego Garcia Military Base, creates uncertainty over the continuing unrestricted use of the Military Base and imposes £35 billion of costs on UK taxpayers for which the Government has no mandate, and that the Government failed to consult the Chagossian people before signing the Treaty”. The House divided:

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 Courtown (Content), Baroness Williams of Trafford (Content), Lord Kennedy of Southwark (Not Content), Baroness Wheeler (Not Content).
