Conservative David Jones says IS represents "an unprecedented threat to international peace and security".
He says "Britain should not be standing by" while France and the US right to "rid the world" of IS.
He will be supporting the motion, but adds "it is entirely honourable" to vote against.
MPs are at the halfway mark in today's debate, with just over five hours to go. A reminder that voting will be taking place at 22:00 GMT - first on the cross-party amendment that opposes UK air strikes in Syria, and then the government's motion which would authorise the bombing.
Green Party MP Caroline Lucas says she "is still to hear convincing evidence" that extending air strikes would improve the security of the UK.
She says the prime minister should "redouble his commendable efforts" to find a diplomatic solution in Syria.
She repeats Julian Lewis's charge that the ground forces the government claims will fight IS are "bogus battalions".

Former Conservative Foreign Secretary William Hague makes his maiden speech in the Lords. He backs the government's approach and calls on the UK to "act with our closest allies".
He argues for "creative diplomacy" over Syria, perhaps a way of calling for engagement with Russia, Iran and others. Lord Hague of Richmond also suggests "smaller, specialist ground forces" from Western nations might be necessary.
Conservative Johnny Mercer says "we are in danger of almost overcomplicating" the issue before the House.
He says IS "hate everything about us" and we have been "asked by international partners to step up, and we must do that".

The Archbishop of Canterbury, Justin Welby, says a policy of air strikes alone "plays into the hands of ISIL and other jihadists in the region". He says such groups have an "apocalyptic vision", adding:

Awula SerwahIsobel (earlier emailer) is right. Instead of continuing the cycle of violence with air strikes we should stop arming the rebels. Air strikes will cause civilian deaths and hep ISIS recruit volunteers. We should act fight ISIS by stopping the flow of arms and finance to ISIS, supporting the intelligence services and by tackling ISIS recruits living in the West, who are planning attacks.
Jesse Harrison LoweYou cannot simply bomb an ideology out of somewhere. By getting involved with military force, we simply give IS more reason to attack us in retaliation. We should use the money ensuring our borders are secure, and stopping any potential threat against us. Bombing is not the answer, look what happened in Iraq.
Ian GriffithsThe proposed air strikes will be no more effective in removing ISIS than the current Russian and Libyans are being. This is a pointless gesture to look good whilst doing very little in real terms. To oust Isis it needs a true fully supported United Nations coalition force on the ground with air support in a coordinated manner including Russia. It needs a comprehensive internationally agreed strategy for the future of the region as a whole with local assent and peace keeping forces for as long as it takes. The general supply of arms to all sides needs to be stopped. Otherwise we will succeed only in making ourselves larger targets by our actions. Doing something inadequate is worse than doing nothing.

I have also been following the debates on air strikes in Syria and have come to completely the opposite conclusion from your recent correspondent. Jeremy Corbyn is in touch with the long-term reality of the situation and trying to avoid the type of short-term reactions which have done so much to create the current situation. David Cameron in contrast is apparently acting for his own glorification. He appears to be more interested in being seen to do something than in achieving a lasting solution. His comments about “terrorist sympathisers” are more about bullying people to get his desired support and diverting attention from the coherent arguments for a complete strategy to deal with terrorism, failed states and the Middle East in general.
Labour MP Pat McFadden attacks the view that terrorism is the fault of the west. He argues that this view "infantalises" terrorists and adds that terrorists are "fully, not partially" responsible for what they do.
He says that we cannot "lie low" and avoid being attacked by terrorists.
He says that the motion being considered is not new, but an extension of action the UK is already involved in in Iraq.

Pip As a Labour Party member, I have viscerally opposed much of David Cameron’s policies. On this however, I have had to open my mind and listen, research and keep on learning on the massively complex issue of Syria and the messy context. I am a pragmatist; I am by instinct a humanist and negotiator. I am not however an appeaser. I very much support the motion to target Daesh in Syria. The case has been successfully made.

I agree with airstrikes going ahead but we need to make sure the Syrian people are safe first. I believe that the UK is at a great threat from a Paris style attack from the evil and perverted ISIS. We have to take military action sooner rather than later because our country could be next.
Jordan WoodleyI completely agree with David Cameron, it is our duty as a nation to answer the call of our allies and the UN and support the fight against IS. IS would not have any intentions of negotiating peace and have proven on many occasions that their only aim is to commit diabolical acts against not only the west, but against the people in the areas they have invaded.
Joan PennieNo-one wants our country to bomb any other country unless it is absolutely essential, but how can the UK sit on the sidelines and expect others to bear the brunt of this issue. How can Syria/Iraq problems be solved by diplomatic means alone if IS takes the countries over with brutal force. We should be protecting innocent Muslims from the terror within their midst.

Crossbench peer and former Army chief Lord Dannatt calls for "constructive dialogue" with Russia, Iran, Turkey and others to develop a common position on Syria.

Lord Wallace of Tankerness, the leader of the Liberal Democrat peers, says he is proud his party opposed the invasion of Iraq in 2003. However, he has a different view of the current case:
Quote MessageUnless something is done to remove ISIL from Syria, there can be no progress towards the goal of a peaceful and stable Syria."
Labour MP Dan Jarvis says he will support the motion tonight.
He says the action taking place in Iraq is "working" and it makes no sense not to extend it to Syria.
He says there "is no realistic strategy" for defeating IS without attacking Raqqah in Syria.
He concludes that the Labour Party has a "proud" history of standing up for the national interest when the country is under threat, and that IS are "the fascists of our time."

"Action against such evil is necessary and it is justified," says Baroness Smith, the Labour leader in the Lords. However, she questions the government's claim that there are 70,000 "moderate ground forces" in Syria. She also questions "the ability of those ground forces to mobilise in the way deemed necessary, given that there aren’t any military command structures". While she has reservations about the government's motion, she notes the recent UN Security Council resolution against so-called Islamic State, adding:
Quote MessageWe clearly should be part of that coalition, seeking to weaken ISIL and to be a credible and authoritative voice in the Vienna talks to bring some peace and stability to Syria and the region."
