The Met Office said Monday night would be cold and frosty for many areas and could be the coldest night across the UK as a whole.

Locally, temperatures could drop as low as minus 9C (15.8F) in rural Scotland and minus 7C (19.4F) in parts of England and Wales.

But a spokesman said the current cold spell may soon come to an end, with temperatures recovering throughout the week.

Throughout the week, more cloud will push through in the south-west from the Atlantic, bringing an increasing chance of rain.

There is also a chance of showers along the North Sea coast and in the far east of Scotland.
