Night-time sub-zero climes are predicted in all four UK nations until at least Friday.

Following a “very chilly” start to Wednesday, the Met Office has issued several yellow weather warnings for snow and ice which may lead to injuries from slips and falls and cause travel disruption.

The warnings for Wednesday cover northern and eastern Scotland until 10am, and Northern Ireland and southern England until 9am.

Forecasters have said in most places the snowfall will continue until Friday, with a yellow warning for snow covering all of the UK north of Birmingham spanning from 3am on Thursday until 6pm on Friday.
