Forecasters say areas of freezing fog, some dense, are expected to form again tonight and into tomorrow, becoming widespread in places.

A spokesman said: "Driving conditions will be difficult with journeys likely to take longer than usual and delays to air travel are possible."

The fog is expected to slowly thin and lift during the day tomorrow, although it may persist in some areas throughout the day.
