Sir Iain Duncan Smith

Conservative — Chingford and Woodford Green

Speaking in the House of Commons on 20 January 2026

Debate

Diego Garcia Military Base and British Indian Ocean Territory Bill

Contribution

I rise because in the previous debate we had on this, a question was posed to Ministers, and it has been asked again now: what are the reasons for this Bill? First, Ministers rested on one idea, which was all about how we had somehow received a binding judgment from the International Court of Justice, and this was therefore important because we had to stand by that. I remember it became clearer and clearer during that debate, particularly for some Members, that this simply was not correct. There is no binding judgment; it is an advisory judgment, because we have an opt-out for all matters to do with Commonwealth Governments. That is very clear, and it has been said by many judges and other learned legal people. Some of my right hon. Friends, one of whom I see on the Front Bench, have raised other reasons in these debates. Beyond the ICJ judgment, we were told there were other issues, and that somehow if we did not do this we would face challenges under the United Nations convention on the law of the sea and by the International Telecommunication Union, which stands steadily. What is most interesting about all this is that, when pressed throughout, bit by bit Ministers’ arguments fell apart. These issues are very detailed, so I will not go into them now, but they will have to be raised in much more detail later.
