London is the capital city of England and of the United Kingdom. An important settlement for around two millennia, London is today one of the world's most important business and financial centres,and its influence in politics, culture, education, entertainment, media, fashion, sport and the arts all contribute to its status as one of the key global cities.
London is the most populous city in the European Union with a population of 7.5 million and a metropolitan area population of between 12 and 14 million. Its population is very cosmopolitan, drawing from a diverse range of peoples, cultures and religions, speaking over 300 different languages. People born in London (this is actually a vaguely-defined term, see below), or who otherwise wish to associate themselves with London refer to themselves as Londoners.
London is an international transport hub, with five international airports and a large port. It serves as the largest aviation hub in the world,and its principal airport, Heathrow, carries more international passengers than any other airport in the world.
