Prime Minister David Cameron will chair a meeting of the National Security Council (NSC) today to discuss possible military action against Syria.
Ahead of tomorrow's recall of Parliament, the NSC, which includes Maidenhead MP Theresa May among its members, is expected to discuss the intelligence gathered by UN inspectors from their visit to Mouadamiya, where last week's suspected chemical weapons attack is believed to have taken place
The council will also consider whether or not to push ahead with a military strike against Syrian president Bashar al-Assad.
Mr Cameron said before the meeting that any intervention in Syria would not be about the conflict itself, but preventing the use of chemical weapons by any regime.
The Archbishop of Canterbury has warned MPs not to rush their decision on whether to vote for military intervention in the Syria conflict.
Ahead of tomorrow's early return to Parliament, the Most Rev Justin Welby said he feared the possible consequences of intervention, saying they were "beyond description and horrible".
He told the Daily Telegraph: "I have had a lot of conversations with people in the region.
"I think the overwhelming sense is of a really moving and terrible sense of fear about what might come out of, what might be happening in the next few weeks - not predicated on people doing one thing or people doing another, just a sense that this a terribly, terribly dangerous time."
However, the Archbishop acknowledged that the Government was better informed than he was, making clear that he had no sense that politicians were "slavering" to "unleash the dogs of war."
