Fog warning covers much of England, Wales and Northern Ireland
The Met Office issued a yellow fog warning across parts of the UK, covering much of southern England and the Midlands, plus areas of Wales and Northern Ireland.
The warning ran from Sunday evening until 11am Monday, with low visibility disrupting rush-hour travel.
More than 30 vehicles crashed on the M20 on Saturday in dense fog, and two people were seriously injured.
Forecasters said clear skies, long nights and light winds created conditions for fog, as the ground cooled and moisture in the air condensed into tiny droplets.
Fog can be patchy and difficult to predict, and cold, still conditions can make it slow to clear.
The Met Office warned that visibility could fall to 50 metres or less in some areas, with possible delays to buses, trains and flights.

What people are saying
We just have the perfect recipe at the moment: light winds, clear skies, long nights, to allow that fog to develop.
Fog is difficult to forecast accurately because it often depends on very local conditions.
