Dozens of flights have been cancelled at Heathrow airport due to thick fog. Britain's busiest airport said the weather had forced the cancellation of about 50 flights on Sunday. A spokeswoman advised passengers caught up in the disruption to contact their airlines. "The fog has been quite bad today," she said. "We've had to cancel flights to keep up with the schedule."

The fog is due to clear by 3pm and no further cancellations or delays were expected, the Heathrow spokeswoman said. Some passengers took to Twitter to describe being stuck because of the cancellations: But others found the change of plans came with a welcome consequence:

The disruption at Heathrow comes on the last day of the school half-term holidays for much of the country.  Paul Knightley, a weather forecaster at MeteoGroup, said: "There is fog and low cloud around from Essex to Devon, through parts of the West Midlands, up to Shropshire and Worcestershire and Merseyside.

"The thick fog is expected to return again tonight so Heathrow could be pretty foggy again tomorrow morning
