Snow, rain and freezing conditions continued to sweep across the UK after the coldest night in nearly two years.
Temperatures plummeted overnight, with a low of -13.5C (7.7F) recorded in the Highland village of Dalwhinnie, while freezing temperatures were recorded as far south as London Luton Airport.

Icy patches are likely on some untreated roads, pavements and cycle paths, while some disruption could be seen to journeys by road, bus and train on affected routes.
Traffic Scotland urged drivers to check their routes before setting off and to ensure they were carrying emergency supplies in case they get stuck.
