A London Transport inspector holding a flare leads a bus out of the terminus at Aldgate East as dense fog blanketed London, causing widespread traffic chaos. The great smog stopped traffic and trains, theatres and cinemas closed because the audience could not see the stage, prize cattle died at Smithfield show at Earl's Court, and the undertakers ran out of coffins

Morning traffic at Blackfriars, London, almost at a standstill because of the blanket smog. There had been smogs before, in every major conurbation. But London was the world's biggest city at the time and nearly all of its 8 million inhabitants used open coal fires. The blanket of cold air from the continent which became stationary over the capital caused the warm, smoke-laden air from homes and power stations to cool and fall back to Earth. It created a blanket of sulfurous smog so dense that visibility was less than half a metre

Heavy smog in Piccadilly Circus, London. The government's policies were at least partly to blame. To maximise revenue the UK was exporting its clean coal and keeping the sulphur-laden 'dirty' coal for UK power stations and domestic fires. The result was a combination of soot laden air and droplets of sulphuric acid lying in a 200ft-deep blanket across London, leading to the worst smog ever recorded

A London bus conductor is forced to walk ahead of his vehicle to guide it through the smog. Government estimates are that 24,000 people a year had their lives shortened as a result of air pollution

Police using flames at Marble Arch to direct the traffic. The great smog was so thick people that could not see their feet. Some of the 4,000 who died in the five days it lasted did not suffer lung problems – they fell into the Thames and drowned because they could not see the river

This Daily Mail picture was taken at sunset from the top of Westminster Cathedral in 1953. London faced another killer smog in 1953 after 48 hours of fog trapped the smoke belching from millions of London's chimney pots

2 January 1954: Arsenal goalkeeper Jack Kelsey peers into the fog, searching for the elusive ball. The fog was so thick the game was eventually stopped. Legislation that followed the great smog of 1952 included the City of London (Various Powers) Act of 1954 and the Clean Air Acts of 1956 and 1968. These acts banned emissions of black smoke and decreed that residents of urban areas and operators of factories must convert to smokeless fuels
