The Channel Islands are not part of the UK or the European Union or the Commonwealth of Nations. They are not even part of the British Overseas Territories. the islands are just off the French coast of Normandy. They claim to be Crown Dependancies and make the UK responsible for their protection, but they do not form part of our systems or taxation which is why tax excites live there. The later may be why they continue to exist. They are Jersey, which is the largest of the islands; and the Guernsey of which Alderney, Sark and some smaller islands are a part of. They have a total population of about 170,000 and both Jersey and Guernsey are often on short and near cruises. English and French are spoken. The UK pound is used though they have their own versions of the pound.
