Question to the Foreign, Commonwealth & Development Office:

To ask the Secretary of State for Foreign, Commonwealth and Development Affairs, what assessment he has made of the potential impact of (a) the International Telecommunication Union and (b) other UN agencies ceasing to recognise UK sovereignty over British Indian Ocean Territory on (i) Gibraltar and (ii) other UK Overseas Territories.

It is the Government's view that without a negotiated solution on the sovereignty of the British Indian Ocean Territory (BIOT), Mauritius would inevitably have pursued a campaign to obtain a legally binding judgment against the UK. We could expect a binding judgment that the UK was not sovereign over the British Indian Ocean Territory, to be applied by international organisations, including UN Specialised Agencies such as the International Telecommunication Union. This would have real-world impacts on the protection and security of the base including our ability to operate the electromagnetic spectrum undisturbed. Regarding impact on other Overseas Territories, BIOT is a unique case. No impact would be expected on other Overseas Territories as the situations are not comparable.
