An attempt to amend the Queen's Speech to express regret that an EU referendum Bill has not been included in the Government's legislative programme has been voted down in the House of Commons.
There were 277 votes against the motion compared with 130 in favour.
The vast majority of those who voted in favour were expected to be Conservative MPs, although Conservative ministers were forced to abstain.
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.
