Fog Causes Heathrow Flight Cancellations
Heavy fog in southern and eastern England has disrupted flights and created hazardous driving conditions for commuters.
Heathrow Airport cancelled 52 incoming and outgoing flights on Wednesday morning.
The Met Office had warned of visibility of less than 50 metres on some of the region's roads.
Sky News' Harriet Hadfield, in west London, said there were reports of "almost no visibility" during the rush hour on motorways such as the M25.
London's City Airport also experienced disruption to inbound and outbound flights, with eight out of 10 flights cancelled or delayed.
Among the services axed were British Airways flights to Zurich, Glasgow and Dusseldorf.
Gatwick operated normally but there were delays and cancellations at Southampton Airport, with no aircraft able to land.
The flight problems follow last Saturday's major disruption at all airports after difficulties at the headquarters of air traffic control company Nats.
Ferry services were also affected by the fog, with delays to Wightlink Ferries - which operates routes between Hampshire and the Isle of Wight.
Customers are being advised to check company websites to get the latest information before travelling.
The fog, which extended to the East Midlands and East Anglia, was thinning in most places by late morning with sunshine breaking through in parts of Kent, Suffolk and London.
