The funeral of Diana, Princess of Wales takes place in London. Well over a million people line the streets and 21⁄2 billion watch around the world on television.

The funeral of Diana, Princess of Wales, started on Saturday 6 September 1997 at 9:08 am in London, when the tenor bell of Westminster Abbey started tolling to signal the departure of the cortège from Kensington Palace. Diana's coffin was carried from the palace on a gun carriage by riders of the King's Troop and escorted by mounted police along Hyde Park to St James's Palace, where her body had remained for five days before being taken to Kensington Palace. The Union Flag on top of the palace was lowered to half mast. The official ceremony was held at Westminster Abbey in London and finished at the resting place in Diana's family estate of Althorp, Northamptonshire.

London is the capital and largest city of both England and the United Kingdom, with a population of 8,945,309 in 2023. Its wider metropolitan area is the largest in Western Europe, with a population of 15.1 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 centuries-long host of the national government and parliament. 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 between the counties of Middlesex, Essex, Surrey, Kent and Hertfordshire, which since 1965 has largely comprised the administrative area of Greater London, governed by 33 local authorities and the Greater London Authority.
