David Cameron has rejected claims an EU referendum will damage the UK economy, criticising those who argue the UK should stay in the EU “come what may”.
The prime minister told business leaders that the UK was securing more inward investment than the whole of the EU despite his 2017 referendum pledge.
He also said he would push for tighter immigration controls despite business concerns over UK skills shortages.
Ed Miliband will also speak later at the CBI’s annual conference.
Meanwhile, Deputy Prime Minister Nick Clegg warned that the UK would have “no future” outside the European Union.
With a general election six months away, the three leaders of the largest Westminster parties are seeking to reassure business leaders that their views on an EU referendum are in the UK’s national and economic interest.
Businesses have warned that the prospect of a referendum is causing uncertainty and could deter them from looking to expand or hiring new workers.
