The London Gazette is one of the official journals of record of the British government, and the most important among such official journals in the United Kingdom, in which certain statutory notices are required to be published. The London Gazette claims to be the oldest surviving English newspaper and the oldest continuously published newspaper in the UK, having been first published on 7 November 1665 as the Oxford Gazette. This title is also claimed by the Stamford Mercury and Berrow's Worcester Journal, because the Gazette is not a conventional newspaper offering general news coverage. It does not have a large circulation.

Other official newspapers of the UK government are the Edinburgh and Belfast Gazettes, which, apart from reproducing certain materials of nationwide interest published in the London Gazette, also contain publications specific to Scotland and Northern Ireland, respectively.

In turn, the London Gazette not only carries notices of UK-wide interest, but also those relating specifically to entities or people in England. However, certain notices that are only of specific interest to Scotland or Northern Ireland are also required to be published in the London Gazette.

London ⁱ/ˈlʌndən/ is the capital city of England and the United Kingdom, the largest metropolitan area in the United Kingdom, and the largest urban zone in 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.

London is a leading global city, with strengths in the arts, commerce, education, entertainment, fashion, finance, healthcare, media, professional services, research and development, tourism and transport all contributing to its prominence. It is the world's leading financial centre alongside New York City and has the fifth-largest city GDP in the world (and the largest in Europe). London has been described as a world cultural capital. It was the world's most visited city during 2011 and London Heathrow is the world's busiest airport by number of international passengers. London's 43 universities form the largest concentration of higher education in Europe. In 2012 London will become the first city to host the modern Summer Olympic Games three times.
