Travellers face further misery as airports, roads and rail services continue to be badly affected by snow.

Chairman of the RAC Foundation David Quarmby, who led a review into the UK's snow strategy, told the programme that the British winters were very unpredictable, with the Met Office suggesting we should expect one in 20 winters to be severe.

"We are not generally well geared up to shifting huge amounts of snow, because we very rarely get this intensity of snowfall," he said.

But Derek Turner of the Highways Agency said it was not true that the country "is in a terrible state".

"The strategic road network is open" he said, adding that there was "no salt shortage at all".

He cautioned, however, that drivers should avoid the roads unless absolutely necessary.
