Commuters face another day of travel chaos thanks to the weather after Britain experienced its coldest night of the year so far.

The mercury plummeted to a bitter low of -13C in Shawbury, Shropshire overnight, while large swathes of the country also fell well below freezing.

The Met Office has extended yellow weather warnings for ice across vast parts of central and southern England, Wales, Scotland and Northern Ireland until 11am, urging drivers to be aware of “icy stretches” on roads.

Major delays are also expected on some rail lines as operators try and compete with the bitter conditions.

Meanwhile, dozens of schools are to stay closed for a second day in a row.
