The Liberal Democrats have called for a National Task Force to tackle the problems of flood defence and management.

They argue it is essential to end the chaos over which organisation is in charge and prevent "even more devastating damage" to parts of Sussex than were suffered in last year's floods.

Environment spokesman Malcolm Bruce said a task force was needed to create an "integrated flood management plan".

This would include planning measures to control building on flood plains and improve drainage in urban and rural areas. It would also be charged with setting up a national insurance scheme.

In a seven point plan presented to the party's annual conference in Bournemouth, Mr Bruce also called for the Environment Agency to be given more power.

He said the agency should be handed overall responsibility for flood defence management and funding.

Mr Bruce told delegates: "This time last year floods wreaked havoc throughout the country.

"It was a devastating wake-up call to the laughable nature of the UK's flood defence strategy.

"We need a single body with the power, responsibility and resources required to deliver a long-term approach to flood defence."
