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.
Commons vote to reject EU Referendum Amendment to Queen's Speech 130 to 277. Majority 147 . Around 115 Tory rebels!From @labourwhips on Twitter:
For those asking, think 10 Labour MPs voted for EU ReferendumFrom @labourwhips on Twitter:
Of 130 MPs who supported John Baron's amendment, I suspect 100-110 are Tory. That is the top end of estimates. That is about half of Conservative backbenchers.
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.
Earlier, Conservative MP John Baron indicated that the number of Tory MPs supporting his motion might be smaller that initially expected.
He said that the draft Bill has kept several of them on side.
Earlier the backbencher John Baron indicated a number of Tory MPs supporting his motion could be smaller than first expected. David Cameron's draft Bill kept several on side.
A ministerial aide tells us he is now abstaining tonight on the vote (he could have a free vote).
He thinks No 10 has done enough with its draft legislation.
MPs have started voting on the amendment to the Queen's Speech expressing regret that an EU referendum Bill has not been included in the Government's legislative programme.
The Prime Minister was forced to point out that the "Conservative party does not do pacts and deals" in response to Nadine Dorries MP's suggestion that she may run on a joint Tory-UKIP ticket in the next election.
He said that his party intended to win the election "outright".
Asked what tonight's vote says about his leadership, the Prime Minister said the vote showed the "strong support there is for a really excellent Queen's speech and governmental programme".
Tory MP Peter Bone, one of the proposers of an amendment to the Queen's Speech, has said that MPs who vote against it tonight will effectively be "voting against an EU referendum".

A vote today for the amendment would give the Prime Minister the moral authority to bring in his EU Referendum Bill as a Government measure.
Members of this House should vote for this amendment because it is in the national interest. It is right that after 30 years the British public should have their say on Europe.
