Diego Garcia Military Base

Lord Ahmad of Wimbledon Excerpts

Tuesday 3rd June 2025 Lords Chamber

[Lord Coaker (Lab)]

I am not sure of the answer to that, but I suspect not. All I can say with respect to this is that, whatever the payment is that the UK Government are making, through the MoD and the FCDO, to the Mauritian Government for the use and protection of the base, we should be clear that the US’s ability to use the base, with its equipment, its facilities, and the soldiers, airmen and sailors of its military, is the massive contribution that the US makes to it. Whatever arrangements we have, the fact that the US and the UK are standing together on that base sends a massive signal to China, the rest of those who stand against us and our adversaries. We are a proud country. We are going to stand with our friends, and we will deter those who seek to undermine us.

[Lord Ahmad of Wimbledon (Con)]

My Lords, may I perhaps inform the Minister? He is, of course, right that the previous Government engaged on this in good faith to try to seek a resolution. The reason why it could not be agreed, as has been said before in your Lordships’ House, was the principal issue of security. I visited at the behest of a previous Prime Minister and directly met the Prime Minister of Mauritius. One assurance that he could not give me at that time was about the long-term security of both the maritime waters and the Diego Garcia base. Linked to that, my specific question is about the other islands that make up the British Indian Ocean Territory. What assurances and, indeed, guarantees are there that there will not be a separate negotiation on them?

[Lord Coaker (Lab)]

My Lords, I know that the noble Lord, Lord Ahmad, will have negotiated in good faith. I know too that if there had been an agreement that he felt was in the national interest then he would have recommended to his Government that it should be supported.

The point that I am making is that the principle was established that negotiations were happening to see what arrangement or agreement, if any, could be made between the UK and Mauritius with respect to Diego Garcia. This Government’s judgment is that we have reached such an agreement. The noble Lord is quite right to point out the security guarantees that we have. He will know that in the treaty there is a 24-mile buffer zone around the island, and the US and the UK can veto any development within that zone. He will also know that there is a further exclusion zone beyond that encompassing the rest of the islands, which means we can prevent development that we are opposed to there as well. That is why we felt we could sign an agreement containing the sorts of security guarantees that the noble Lord himself sought but did not manage to achieve, and therefore did not feel there was an agreement that he could come to or recommend we agree to. We feel that we have guarantees that will protect the integrity of the base by excluding others who would seek to undermine it.
