Hundreds of homes have been evacuated and dozens of cars abandoned by drivers after widespread flooding across the UK.
Flood warnings are in place across Britain as rivers burst their banks and forecasters say there is more bad weather to come.

Other areas in England, Wales and Scotland have also been flooded, with 79 flood warnings and 143 flood alerts currently in place.

Heavy rain and strong winds are forecast to return to some southern areas with 20mm to 40mm (0.8in to 1.6in) likely in places into Wednesday. There is also no sign of the downpours easing in the Midlands.

The Environment Agency is urging people to sign up to its flood alerts and has issued guidance to residents who may be affected by flooding.
Kath Evans, from the Environment Agency, told Sky News that the situation had been made worse by the wet summer.
"With the rainfall over the summer and more falling over the last 24 to 36 hours, it has caused this widespread flooding," she said.
She said they were watching areas around the River Ouse in Yorkshire and the River Severn as the water moved downstream and would "urge people to keep an eye out and listen out for flood warnings".
Communities in Yorkshire, the North West and North Wales were urged to remain on guard for further floods.
In Morpeth, parts of the town were evacuated as a precaution before the river burst its banks and some 40 stranded residents were rescued using lifeboats, although water levels later appeared to have peaked.

Disruption and delays hit a number of other railway lines in northern England and Wales.
The heavy rain is due to an area of low pressure which moved north across the country from the Bay of Biscay.
The Met Office said an area of low pressure measuring 973 millibars had been recorded near the coast of the north east of England - the lowest in the UK for September since 1981.
