UPDATE 23:22:

PRIME Minister David Cameron has ruled out UK involvement in military action over Syria after the Government lost tonight's vote - 285 to 272.

David Davies, MP for Monmouth, had tweeted ahead of the vote that he was going to vote against the coalition.

He wrote: "PM spoke very well today. Said its a judgement call. My judgement differs & tonight with great regret must vote against govt."

Paul Flynn, MP for Newport West, tweeted: "Cameron's humiliation. He re-called a Parliament which rejected his call to blunder into a new futile war. Victory for Parliament."

BRITAIN is being drawn into war to allow Obama to save face, Newport West MP Paul Flynn told tonight's marathon debate on Syria.

Gwent parliamentarians were among those recalled to parliament on Thursday to discuss possible military action against the Bashar Assad government for alleged use of chemical weapons.

Prime Minister David Cameron admitted that there can be no “100 per cent certainty” about who committed the chemical weapons attack near Damascus, but insisted it was "beyond doubt’’ Bashar Assad's regime was responsible.

The Prime Minister was forced to accept the need to give United Nations inspectors time to report on the attack and proposed for MPs to be given a further vote before authorising direct British involvement in any strike against Syria.

But the UK Government's concessions did not go far enough for Labour leader Ed Miliband, who has tabled an alternative motion demanding "compelling evidence’’ that the Assad regime was responsible.

MPs had not voted on either motions before the Argus went to press.

Newport West MP Paul Flynn said that in his time in the house chemical weapons had been used against the Kurds, in the Iran/Iraq war and against the people of Gaza.

“Isn’t the real reason we’re here today, is not because of the horror of these weapons and the horror exists – but because the American president foolishly drew a red line and because of his position now, he's going to attack or face humiliation. That’s why we’re being drawn into war,” he said.

Mr Flynn also referred to the decision to deploy British troops to the Helmand province of Afghanistan in 2006: “The results of accepting those decisions led to 623 UK deaths. These are the reasons why the public has lost trust in government choices on going to war.”

Addressing MPs Mr Cameron said: "When people talk about escalation, to me the biggest danger of escalation is if the world community, not just Britain but America and others, stand back and do nothing because I think Assad will draw very clear conclusions from that.’’

Labour leader Ed Miliband insisted he is not ruling out military intervention in Syria but the potential consequences of such action needs to be clear. He said MPs need to consider how it is possible to make the lives of the Syrian people better while upholding international law and legitimacy.
