History: London, England, United Kingdom

Geography
Scope
Greater London is the top-level administrative subdivision covering London. The small, ancient City of London at its core once contained the whole settlement, but as the urban area grew the City Corporation resisted attempts to amalgamate it with its suburbs, causing "London" to be defined in a number ways for different purposes; and the situation was once open to legal debate. Forty per cent of Greater London is covered by the London post town, within which 'LONDON' forms part of postal addresses.
