Foreign Secretary William Hague has denied being embarrassed that 114 Conservative MPs voted in favour of an amendment to the Queen's speech, insisting it was a "free vote".
He added that the "whole [Conservative] party would like to be able to proceed with legislation" for an EU referendum, but that it was constrained by its Lib Dem coalition partners.
The Press Association has a breakdown of the MPs who voted for a Tory MP's amendment to the Queen's Speech expressing regret that David Cameron had not included an EU referendum bill in its legislative plans for the upcoming year:
- 114 Conservatives
- 12 Labour
- One Lib Dem
- Four DUP
188 Conservatives did not vote. Tory members of the Government were told to abstain.
– Shadow Foreign Secretary Douglas Alexander
This vote is a further devastating blow to the Prime Minister's authority.
It demonstrates that David Cameron has managed to turn a Europe issue into a leadership issue.
This is a Prime Minister who has lost control of the agenda and tonight lost control of his Party.
David Cameron’s backbenchers have shown they simply won’t give up until he gives in.
The real risk is that he spends the coming month trying to get his party back in line, instead of focusing on getting our economy back on track.
Foreign Secretary William Hague has said that if any MP - Tory or otherwise - decides to take up the Private Members' Bill on an EU referendum, then the Conservative party "will get behind that".
But he added that he was not "predicting that legislation can necessarily be passed".
Richard Corbett, who advises the European Council President Herman Van Rompuy, has said that Brussels sees tonight's vote as an internal debate, adding that "some would say [it is] an internal debate within one particular party".
Speaking to BBC News, he likened Britain leaving the EU to "economic suicide" and said that 3.5 million jobs would directly suffer.
"Where now?" I ask John Baron MP after the vote. "How much longer will you bang on about an EU referendum?"
He replies that he will keep going until there is legislation for an EU referendum.
The Conservative MP John Baron tells me 115 Tories supported his amendment expressing regret that the Government had not included an EU referendum Bill in the Queen's Speech.
An unexpectedly high 130 MPs voted in favour of an amendment to the Queen's Speech to express regret that an EU referendum Bill was not included today.
A number of Conservative MPs are identifying themselves as having voted in favour of the amendment to the Queen's Speech on Twitter.
