Many flights at Heathrow and Gatwick cancelled or delayed on Saturday as murky conditions persist
Heavy fog that severely limits visibility has led to further cancellations and delays of dozens of flights at Heathrow and Gatwick, and is forecast to persist through the weekend.
The murky weather has shrouded much of the country over the past few days and showed little sign of abating on Saturday. In some areas, thick fog patches could reduce visibility to just 100 metres, the Met Office said.
