Diego Garcia and British Indian Ocean Territory

Wendy Morton Excerpts

Wednesday 25th February 2026 Commons Chamber

[Mr Speaker]

I call the shadow Minister.

[Wendy Morton (Aldridge-Brownhills) (Con)]

Labour’s Chagos surrender is a shameful, unnecessary and reckless deal that will leave Britain weaker, poorer and less secure. This is not a legal necessity but a political choice made by a floundering Prime Minister, and it is British taxpayers who will be left to pay the price. No other Government would pay £35 billion to hand over their own sovereign territory and make their country less secure in the process. At a time when families are being squeezed, Ministers are asking them to subsidise another country’s budget, potentially funding tax cuts in Mauritius while taxes rise here at home. That is indefensible. Can the Minister therefore confirm that no payments will be made under the treaty of the so-called strategic partnership unless and until ratification is fully complete?

This is also a national security crisis. Diego Garcia is one of the most strategically vital military bases in the world, yet Ministers are pressing ahead before resolving the binding 1966 UK-US treaty, before addressing concerns raised by President Trump, and without guaranteeing that the lease can never collapse or be legally challenged. On the United Nations convention on the law of the sea, will the Minister confirm that article 298 provides an opt-out from compulsory dispute settlement for military activities, meaning that this is a political choice, not an unavoidable legal trap?

Will the Government suspend the Bill until the legal position with the US is settled and any amendments have been scrutinised under the Constitutional Reform and Governance Act process? Will the Minister confirm whether the Pelindaba treaty would apply if Mauritius were to take sovereignty, and if so, what iron-clad safeguards protect our nuclear deterrent?

Finally, what of the British Chagossians, some of whom are now on the islands? Can the Minister guarantee that there will be no forced removal and that their rights will be protected in full? British sovereignty is not for sale, and this House should not be bounced into surrendering it.

[Mr Falconer]

As I have said, I would find the Conservatives’ position more plausible had they not held 11 rounds of these negotiations. The attempt by Conservative and Reform Members to act as though there was no issue to be addressed, and as though the reason they started 11 rounds of negotiations was some sort of lack of focus—[Interruption.] If there was no issue to address, I am not sure why right hon. and hon. Members in the previous Government began the negotiations. I can assure the House that the treaty will go through the full parliamentary process in the usual way, and we are discussing these questions with the Americans in the usual way.
