Drivers and passengers using Britain's roads and railways are being warned to expect disruption as freezing conditions continue to cause havoc across the country.

Delays and cancellations to travel services were reported across the UK after the coldest night of the year.

Clear skies overnight saw temperatures plummet below the -12.4C recorded on Saturday night, with -13C recorded in Shropshire.

The Met Office issued a yellow weather warning, covering large parts of the country, including much of the Midlands, Scotland and Wales.

The AA said drivers should expect hazardous conditions on the roads while travellers attempting to reach France using the Eurotunnel were warned about delays of up to six hours.

At Heathrow, where dozens of flights were affected on Monday, 16 departures were listed as cancelled for Tuesday with the airport advising passengers to check the status of their flight before travelling to the airport.

Cancellations are also reported at Birmingham, Manchester and Edinburgh airports.

Airlines had previously said the re-positioning of aircraft and crews from previous days was adding to the problems.
