The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign statelocated off the north-western coast of continental Europe. The country includes the island of Great Britain (a term sometimes loosely applied to the whole state), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another state: the Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea in the east, the English Channel in the south and the Irish Sea in the west. The UK's form of government is a constitutional monarchy with a parliamentary system, and its capital city is London. The current British monarch—since 6 February 1952—is Queen Elizabeth II. The United Kingdom consists of four countries: England, Scotland, Wales and Northern Ireland.The latter three havedevolved administrations, each with varying powers, based in their capital cities, Edinburgh, Cardiff and Belfast, respectively. Guernsey, Jersey and theIsle of Man are Crown dependencies and are not part of the UK. The United Kingdom has fourteen British Overseas Territories. These are remnants of theBritish Empire which, at its height in the late 19th and early 20th centuries, encompassed almost a quarter of the world's land mass and was the largest empire in history. British influence can be observed in the language, culture and legal systems of many of its former colonies. The United Kingdom is a developed country and has the world's sixth-largest economy by nominal GDP and eighth-largest by purchasing power parity. It was the world's first industrialised country and the world's foremost power during the 19th and early 20th centuries. The UK remains a great power with considerable economic, cultural, military, scientific and political influence internationally. It is a recognised nuclear weapons state and its military expenditure ranks fourth in the world. The UK has been a permanent member of the United Nations Security Council since its first session in 1946. It has been a member of the European Union (EU) and its predecessor the European Economic Community (EEC) since 1973; it is also a member of the Commonwealth of Nations, the Council of Europe, theG7, the G8, the G20, NATO, the Organisation for Economic Co-operation and Development (OECD) and the World Trade Organisation (WTO).
