Disruption is continuing at Gatwick Airport for a fourth day after heavy fog affected flights in one of the busiest periods of the year. Some restrictions due to adverse weather remain in place, the airport said.

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.

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