London is the capital and
largest urban area of England and the United kingdom. At its core,
the ancient city of London, to which the name historically belongs,
still retains its limited mediaeval boundaries, but since at least
the 19th century the name "London" has also referred to the whole
metropolis which has developed around it. Today the bulk of this
conurbation forms the London region of England and the greater
London administrative area, with its own elected mayor and assembly.
