London is the capital and largest city of England and the United Kingdom, with a population of 9.14 million people in 2025. Its wider metropolitan area is the largest in Western Europe, with a population of 15.4 million.
London stands on the River Thames in southeast England, at the head of a 50-mile (80 km) tidal estuary down to the North Sea, and has been a major settlement for nearly 2,000 years. Its ancient core and financial centre, the City of London, was founded by the Romans as Londinium and has retained its medieval boundaries.
The City of Westminster, to the west of the City of London, has been the site of the national government and parliament for centuries. London grew rapidly in the 19th century, becoming the world's largest city at the time.
Since the 19th century the name "London" has referred to the metropolis around the City of London, historically split among the counties of Middlesex, Essex, Surrey, Kent and Hertfordshire. Since 1965 it has largely comprised the administrative area of Greater London, governed by 33 local authorities and the Greater London Authority.

Note on DST transitions: The offsets shown above reflect the current live offset, which changes twice a year due to Daylight Saving Time. Different regions change their clocks on different dates, which means the difference between London and another city can vary by 1 hour for a short period in spring and autumn. Always verify the exact time difference around DST transition dates for critical scheduling.
