British possessions

Extracted from the Wikipedia article British possession.
Overview
In common statutory usage the British possessions include British Overseas Territories, and the Commonwealth realms but not protectorates. British admiralty law has a less expansive meaning under the Merchant Shipping Act 1995, where a "relevant British possession" includes the Crown Dependencies (the Isle of Man and the Channel Islands) and "any colony" (the self-governing British Overseas Territories). It may also be used more expansively, to refer to member states of the Commonwealth of Nations which have a continuing tradition of British law even after they have become republics, and even if those countries no longer recognize themselves as British possessions.
