The United Kingdom, officially the United Kingdom of Great Britain and Northern Ireland, is a sovereign island country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands within the British Isles.
The United Kingdom is one of the eighteen British Commonwealth Realms and thus a member of the Commonwealth of Nations. It is also a member of the United Nations, the Asia-Pacific Treaty Organisation, and the North Atlantic Treaty Organisation.
