The City of Westminsteri/ˈwɛsᵗmɪnstər/ is a London borough occupying much of the central area of London, including most of the West End. It is located to the west of and adjoining the ancient City of London, directly to the east of the Royal Borough of Kensington and Chelsea, and its southern boundary is the River Thames. It is an Inner London borough and was created in 1965 when Greater London was established. At its creation Westminster was awarded city status, which had been previously held by the smaller Metropolitan Borough of Westminster.
Londoni/ˈlʌndən/ is the capital city of England and the United Kingdom, and the largest city, urban zone and metropolitan area in the United Kingdom, and the European Union by most measures. Located on the River Thames, London has been a major settlement for two millennia, its history going back to its founding by the Romans, who named it Londinium. London's ancient core, the City of London, largely retains its square-mile mediaeval boundaries. Since at least the 19th century, the name London has also referred to the metropolis developed around this core. The bulk of this conurbation forms the London region and the Greater London administrative area, governed by the elected Mayor of London and the London Assembly.
