David Cameron has warned that a Labour government would cost the taxpayer billions of pounds because of its failure to control the public finances.

With the main political parties starting the new year on a clear election footing, the Prime Minister said Labour's economic mismanagement would cost £13.5 billion in extra interest payments.

In an interview with The Sunday Times (£) , Mr Cameron said: "There is nothing caring about the risks Labour would take with the economy and all our futures.

"They've made clear they'll keep adding to our debt - costing breathtaking amounts of money in extra interest payments alone.

"Money that should be used for schools and hospitals will be effectively poured down the drain."

Mr Cameron went on the offensive as Labour mounted its own assault, with a warning that the NHS would not survive in its present form after another five years of Conservative government.

The Prime Minister however sought to cast the election as a choice between security under the Conservatives and "chaos" under any of the alternatives.
