Motorists warned to 'be patient on snowy roads'

Heavy snow is set to cause disruption across many parts of the UK as forecasters predict some areas could see up to 30cm of snow.

A rare red Met Office warning for snow is in place for parts of Wales, meaning severe disruption is likely.

There is an amber warning for Northern Ireland and most of England, with snow also due in parts of Scotland.

The BBC's John Maguire reports from near the M5 in Somerset where he spoke to Tim Shallcross from the Institute of Advanced Motorists.
