London is the capital city of England and of the United Kingdom, and is the most populous city in the European Union.
London's metropolitan area grew considerably during the Victorian era and again during the Interwar period with expansion halted in the 1940s by World War II and Green Belt legislation and has been largely static since.
London's other financial hub is the Docklands area in the east of the city, dominated by the Canary Wharf complex, whilst many other businesses locate in the City of Westminster which is the home of the UK's national government.
