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.

London Luton Airport (IATA: LTN, ICAO: EGGW) (previously called Luton International Airport) is an international airport located 1.5 NM (2.8 km; 1.7 mi) east of the town centre in the Borough of Luton in Bedfordshire, England and is 30.5 NM (56.5 km; 35.1 mi) north of Central London. The airport is 2 mi (3.2 km) from Junction 10a of the M1 motorway. It is the fourth-largest airport serving the London area after Heathrow, Gatwick and Stansted, and is one of London's six international airports along with London City and Southend.

In 2008, over 10 million passengers passed through the airport in a single year for the first time. However, passenger numbers were slightly lower during 2011 at 9.5 million, making Luton the fifth-busiest airport in the UK. The airport serves as a base for EasyJet, Monarch Airlines, Thomson Airways and Ryanair. The vast majority of the routes served are within Europe, although there are some charter and scheduled routes to destinations in Northern Africa and Asia.

Luton (ⁱ/ˈluːtən/ LOOT-ən, local /ˈluːʔən/) is a large town, borough and unitary authority of Bedfordshire, England, 30 miles (50 km) north of London. Luton and its near neighbours, Dunstable and Houghton Regis, form the Luton/Dunstable Urban Area with a population of about 250,000.

Luton is home to Blue Square Premier team Luton Town Football Club, whose history includes several spells in the top flight of the English league as well as a Football League Cup triumph in 1988. They play at Kenilworth Road stadium, which has been their home since 1905.

London Luton Airport, opened in 1938, is one of England's major airports. During the Second World War it doubled as an RAF base.

The University of Bedfordshire is based in the town.

The Luton Carnival, held on the late May bank holiday, is the largest one-day carnival in Europe.

The town was for many years famous for hat-making, and was also home to a large Vauxhall Motors factory; the head office of Vauxhall Motors is still situated in the town. Car production at the plant began in 1905 and continued until 2002, but commercial vehicle production remains.
