Britain must shore up flood defences - PM Brown

LONDON (Reuters) - Prime Minister Gordon Brown said Britain must do more to boost its flood defences after the worst floods in 60 years left 350,000 people without drinking water and power supplies on the brink of mass blackout. 

"We are looking at 21st century extreme weather conditions," Brown told BBC Television after a tense day monitoring how emergency services coped with the flooding that deluged huge swathes of central and western England.
