SNP international affairs spokesperson Alex Salmond says that anyone who thinks the bombing will not cause civilian casualties "is living on a different planet".

He says the prime minister was wrong to "demean himself" by describing opponents of air strikes as "terrorist sympathisers."

He says there is no "exit strategy" and the house should reject the motion.

Parliament

Shadow leader of the Lords, Lord Baroness Smith of Basildon, says many MPs asked to reach a decision today on military action will not do so with "absolute confidence". She argues that "for most of us, it's not like that" and, unless someone is an expert in the subject, they will wish to listen to the arguments. The Labour peer adds that "many MPs with the same information" will come to different conclusions, and condemns "those who abuse, intimidate or threaten them".

Conservative Gary Streeter says he will be supporting the government.

He says he "trusts" the security briefing provided by the prime minister, which says there are 70,000 ground troops available in Syria to fight IS.

He says "it makes no sense" to attack IS in Iraq but but in Syria, as we are doing now. 

He says we "are being attacked" by "ruthless barbarians", and they must be defeated.

Labour MP David Winnick says MPs should be free to vote without "threats" from outside.

He says there is a growing public unease about extending air strikes to Syria, which he shares. 

He notes that "everyone" says ground troops are needed, but the motion rules out sending them.

He says that "with some reluctance" he will be opposing the motion.

Labour MP Khalid Mahmood says air strikes alone will not tackle so-called IS, and says that troops on the ground will be needed.

He says these troops must come from a "coalition" of nations, including Muslim countries.

Leader of the House Baroness Stowell of Beeston sets out the government's case for air strikes on Syria.

Conservative David Davis says that he doubts that extending air strikes to Syria will be effective.

He calls on Turkey to shut the border with Syria, so Isis cannot use it to obtain funding.

David Cameron's case for British bombing in Syria was "utterly unconvincing", writes The Mirror's Kevin Maguire, external. Offering his assessment in the Labour-backing paper of the prime minister's statement, he adds:

The government's chief whip in the Lords, Lord Taylor of Holbeach, says backbench peers should observe a four minute limit for today's speeches. "The whips have been instructed to deal firmly with noble lords who exceed the speaking time," he says.

Labour's Gisela Stuart says she is relieved that her email in-box is full of people lobbying her to vote against air strikes.

She says that she will be supporting the motion "because it is good enough", and is "in the national interest".

House of Lords
Parliament

The House of Lords' debate on air strikes in Syria begins. Unlike MPs, peers will not hold a vote on whether or not to endorse military action. The motion in the Lords asks that the House "takes note of Her Majesty’s government’s proposals for military action". The debate is expected to conclude before the Commons vote takes place.
