Flight restrictions remain in place at Gatwick Airport for a fourth day because of fog, disrupting travel plans for thousands of passengers. More than 20 flights planned for the West Sussex airport on Monday were cancelled in advance and passengers are being warned of delays throughout the day.

Fog is continuing to disrupt flights at Gatwick Airport with restrictions imposed to maintain safety. On what is expected to be the airport's busiest day of the Christmas period, it said some flights "may be delayed throughout the day" due to "poor visibility" and apologised to customers.

It follows two days of disruption at the UK’s busiest airports, with Saturday’s flights at Stansted Airport affected by the murky conditions, while live departure boards showed delays at Heathrow, Luton, Gatwick and Manchester Airports.
