Speaking in the House of Lords on 25 November 2025

Debate

Diego Garcia Military Base and British Indian Ocean Territory Bill

Contribution

My Lords, I associate myself with the remarks of my noble friend Lord Callanan on the amendments to which he spoke. I shall be dealing with the word “expeditiously” and I will try to ensure that that characterises my contribution, and perhaps influences this debate. I wish to speak to my Amendments 83, 85, 86 and 87. At Second Reading, I raised the issue of the mismatch between the Bill and the treaty that it implements. My main concern in this whole affair is our defence and security and the implications of this Bill on that. I identified a range of areas where greater clarity is required. Before I continue, I should say that I have received a letter from the Ministers, for which I thank them. That sought to clarify some of the questions that I asked at Second Reading. The letter brings a degree of clarification, but in other respects it leaves me with questions. I shall address these as I explain my amendments. Amendment 83 is simply a technical drafting amendment to accommodate my remaining amendments in this group. It specifies that the commencement of the treaty cannot occur until the conditions outlined in my amendments have been satisfied. Amendment 85 relates to the specific notification requirements under Annex 1 1(b)(viii) of the treaty. My amendment would require that Clauses 2 to 4 do not come into force until the Secretary of State has published a statement establishing that the notification in Annex 1 1(b)(viii) of the treaty does not require the consent of Mauritius in response. The provision in Annex 1 to which this refers says that: “In accordance with this Agreement and with reference to Article 2(5) and Annex 2, in respect of Diego Garcia, Mauritius agrees the United Kingdom shall have … unrestricted access, basing and overflight … for non-United Kingdom and non-United States of America aircraft and vessels, upon notification to Mauritius”. The amendment seeks to enable the Secretary of State to make explicit, before Clauses 2 to 4 of the Bill can come into force, that the consent of Mauritius is not required for us to host third-party forces on Diego Garcia. As I mentioned, I have the letter from the Ministers in which they helpfully clarify that permission from Mauritius is not required. However, I require the Minister to confirm that such notification is after the event. If notification is required before the event, that implies consent is required, or that the intimation of an objection by Mauritius is possible. That is why I seek the clarification. We cannot have a situation where Mauritius can in any way object to which forces are present at the base. The operation of the base, including the matter of the basing of our allies, must be solely at the discretion of the United Kingdom. I would appreciate the Minister giving a guarantee that Mauritius will have no control whatever over the basing and overflight of other countries’ forces. Unusually, the Minister and I are perhaps nearly at consensus in idem here. If that is the case, why would the Secretary of State be reluctant to publish a statement? Amendment 86 is another defence and security amendment. It seeks that Clauses 2 to 4 would not come into force until the Secretary of State has published a statement establishing that the obligation under Annex 1(2) of the treaty “does not extend to aircraft and vessels which have landed or docked at the Base for the purposes of maintenance or refuelling prior to the armed attack on a third state”. Annex 1(2) of the treaty is the provision that requires the United Kingdom “to expeditiously inform Mauritius of any armed attack on a third State”. As we have discussed, much has been made of what is meant by “expeditiously”. The Ministers’ letter to me stated that they are satisfied that this does not require the UK to seek the permission of Mauritius, nor for notification to be given prior to the event. That is helpful. The International Agreements Committee of this House has also concluded that it interprets “expeditiously” to mean “as soon as reasonably practicable in the circumstances”. I believe that the Minister gives her interpretation in good faith, but what of Mauritius’s interpretation? Does the Minister know whether the Mauritian Government share this view? If she does not currently know, and I quite accept that she may not, I would be happy for her to write to me to confirm the point.
