Disruption continues at Gatwick Airport for a fourth day as thick fog causes flight cancellations and delays during the airport’s busy holiday period. A spokesperson for the airport has confirmed that air restrictions will be kept in place because of low visibility in airfields affected by fog.

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.

Tens of thousands of passengers have had their Christmas travel disrupted in recent days as thick fog has descended on airports.
