Britain retains sovereignty over 14 territories outside the British Isles, which were renamed the British Overseas Territories in 2002. Some are uninhabited except for transient military or scientific personnel; the remainder are self-governing to varying degrees and are reliant on the UK for foreign relations and defence. The British government has stated its willingness to assist any Overseas Territory that wishes to proceed to independence, where that is an option. British sovereignty of several of the overseas territories is disputed by their geographical neighbours: Gibraltar is claimed by Spain, the Falkland Islands and South Georgia and the South Sandwich Islands are claimed by Argentina, and the British Indian Ocean Territory is claimed by Mauritius and Seychelles. The British Antarctic Territory is subject to overlapping claims by Argentina and Chile, while many countries do not recognise any territorial claims in Antarctica.
