Heavy snowfall and widespread ice have led to another day of travel disruption, amid warnings that Britain is set to be gripped by freezing weather all month.

As police forces told of treacherous driving conditions on Tuesday after the mercury plummeted further overnight, the Met Office said a "prolonged cold period" with below average temperatures was expected for "much of February and perhaps even into March".

What was predicted to be the UK's coldest week of the winter began with lows of -6C on Monday. Forecasters said temperatures will dip further on Tuesday night, with predicted lows of -14C before the weekend.

Commuters again faced travel delays on Tuesday, with snowfall triggering multiple pile-ups on motorways and cancelled flights.

Snow is set to fall in almost every part of the country in the coming days, with a series of weather warnings in force.
