The Labour Leader Ed Miliband has accused David Cameron of being the leader of a weak and divided party, as the Conservatives split over the issue of Britain's membership of the European Union.
"What we see today is a Labour Party focused on jobs and living standards and sorting out our economy and a Conservative Party where David Cameron has completely lost control" he said.
"They're arguing amongst themselves about Europe and not sorting out the problems of the country".
"Frankly, this has not just become an issue about Europe, but about David Cameron's weak leadership of his party".
Cameron has pledged to back a Conservative MP's EU referendum bill, as Cable labelled the move potentially 'damaging' for the country.
114 Conservative backbenchers have voted in favour of a eurosceptic motion to amend the Queen's Speech in defiance of the Prime Minister.
David Cameron has denied he has buckled under pressure from his backbench MPs over the EU debate.
