Two North Yorkshire hospitals are urging people to consider other NHS healthcare options first as staff cope with pressures from the extreme weather.

The plea comes from Harrogate Hospital, which has offered staff lifts in four wheel drive vehicles, so they can get to work today, and The Friarage, in Northallerton, which says people should only attend if absolutely necessary.

Mike Forster, from Harrogate Hospital, says patients should still go there if they need treatment, but says people should get advice on exploring alternatives:

Harrogate hospital praised their staff on Twitter yesterday evening, saying some of them travelled for more than five hours to get to work to help patients and support their colleagues.

Virgin Trains East Coast is advising customers travelling to and from Scotland, from stations across Yorkshire not to travel today.
