There are specific arrangements in the treaty that prevent any foreign power from putting security apparatus or security forces on any of the outgoing islands. The right hon. Gentleman will be able to see that when the treaty comes before the House. In relation to the support of the United States, we would not have signed an agreement if it was not supported by our US friends. This deal secures the operation of the UK-US base on Diego Garcia well into the next century. I expect that when everyone looks at the detail of the deal, they will back it too.
