       The cancellations come as yellow wind and rain warnings are in place across most of the country, while there is a risk of snow further north.

       Warnings have been issued by the Met Office for today and Thursday, with winds of up to 70mph possible in some areas.

       Wintry hazards also likely, especially across northern Scotland, where yellow weather warnings for snow have been issued.

       There are wind warnings out for the south of England, across the English Channel coast.

       People planning to travel back home after the Christmas holidays have been urged to take care on the roads.

       It is likely these will lead to transport disruptions, with the Met Office warning journeys will be taking longer today.

       A British Airways spokesman apologised to customers for the disruption and said they are working hard to get travellers on their way "as quickly as possible".

       Drivers across the UK are being warned of potentially hazardous conditions on their way home from the Christmas holidays.
