Widespread transport disruption across England and Wales is expected this morning following significant overnight snowfall and sub-zero temperatures.

People travelling to Heathrow have been advised to check their flight’s status before setting off and allow extra time for their journey after it was hit by show overnight.

However, officials said no disruption is expected at the airport.

A Heathrow spokesman said: “We’re running a normal schedule today but always check with your airline too.”

Gatwick, London Luton, Birmingham, Stansted, Bristol and Bournemouth said they were open and operating as normal and were not expecting disruption despite the wintry weather.

Some flights from Leeds/Bradford were cancelled last night with the airport blamed adverse weather conditions for delays this morning. Passengers should check with their airline or tour operator before arriving at the airport.

The disruption followed snow last night falling in the North and the Midlands before gradually hitting the Home Counties, East Anglia, London, the South East, the South West and Wales.

Motorists are being warned of treacherous road conditions after more than two inches of snow blanketed some regions and the mercury plunged to -4C.
