Flood water: Fears of pollution with sewage
The prime minister has repeated his pledge to spare no effort in helping flooded communities to get back on their feet.
He said £5,000 would be available for households and businesses to protect their properties for the future and there would be a £10m fund for farmers.
Meanwhile tests have been carried out to see what bacteria is in the flood water that has invaded so many homes.
