'Business backs Tories on EU vote' says David Cameron

Prime Minister David Cameron says business leaders are increasingly backing his plans for an EU referendum after a renegotiation of the UK's role within the EU.

British Chambers of Commerce (BCC) chief John Longworth has called for a vote in 2016, a year earlier than Mr Cameron has promised, to end uncertainty.

Labour's Ed Balls has warned a referendum would be "hugely destabilising" to business.

But Mr Cameron said the BCC boss's call showed firms were getting behind him.
