David Cameron tells CBI: 'EU vote will not harm economy'

A referendum on Britain's membership of the EU will not damage the UK economy, David Cameron has told business leaders.

The prime minister also told the CBI conference in London that he would push for tighter immigration controls, despite business concerns over UK skills shortages.

Deputy Prime Minister Nick Clegg warned delegates that the UK would have "no future" outside the European Union and Ed Miliband told the conference the Prime Minister was putting the country on the conveyor belt to an EU exit.
