London weather:
Coldest night for 12 years recorded as temperatures drop to -8.4C
It comes as around 80 flights from Heathrow were cancelled overnight due to the freezing and foggy conditions at the airport.
Temperatures in the area were still as low as -7C at 8am on Monday, while -8C was recorded in Northolt at dawn.
The sub-zero temperatures last night meant that London was actually colder than Moscow, which recorded lows of -4C, and Winnipeg, which was -3C.
Fog in parts of London has also affected road travel, with visibility in Surbiton, South London, being reduced to just 100 yards.
