  2. Withour air strikes in Syria UK's influence 'weakened'

    Crispin Blunt

    Conservative MP and Chair of the Foreign Affairs Committee Crispin Blunt says "whether we like it not Isil is at war with us".

    He says "the retaking of territory" from IS is "urgent."

    He argues the UK needs to influence the "policy of the whole international community" to confront IS, and while we are only operating in Iraq our influence is "weakened".

    He says he will support the motion, but wants it to go further, and that stating UK ground troops will not be involved "shows a lack of foresight".

  3. Labour MP Kaufman says air strikes would be a 'gesture'

    Sir Gerald Kaufman

    Labour MP Sir Gerald Kaufman says that if the government was proposing a course of action which would "weaken" IS he would support it, but there is "no evidence of any kind" that air strikes would encourgae others in the region to fight them.

    He says air strikes would kill civilians for "what would simply be a gesture."

    He will vote against the government. 

  4. 'National embarrassment' to leave action to allies

    Liam Fox

    Conservative MP and former Defence Secretary Liam Fox says "we have not chosen this confrontation, they have chosen to confront us".

    He says that no conflict is ever won from the air alone, and that ultimately there needs to be an international coalition of ground forces to win.

    He argues that although air strikes will not defeat IS, they "will help."

    He adds that it is a "national embarrassment" for Britain to "contract out" our security to our allies, and says that he will support the government.

    The strikes are needed to once again show we are a nation who will support our allies. We must accept though if we do drop bombs on ISIS then we must be fully prepared for the backlash when they enter London at some time.

    Angus Robertson

    Angus Robertson

    SNP Westminster leader Angus Robertson speaks to the amendment in his name. The amendment says the case for the UK participating in air strikes has not been made.

    Mr Robertson asks how many of the 70,000 ground troops the prime minister has said are capable of fighting IS are moderate and how many are fundamentalists?

    Labour MP Yasmin Qureshi,intervenes to say that when she asks people from the region they say there are only around 10,000 to 15,000 ground troops available in Syria.

    Angus Robertson describes this as a "very important intervention."

    It’s undeniable that bombing will have an impact on ISIS.  Of course it will, for a time, disrupt their logistical capabilities – but it’s exactly that sort of short-term thinking that makes it easy to get into wars and impossible to get out of them.  Extreme actions breed extreme responses, and bombing need only inspire a handful of people outside of Syria to take the leap into extremism for the whole ‘protecting our interests’ argument to become instantly redundant.

    The longer we do not use military action on ISIS, the higher the chance we leave ourselves exposed to an attack regardless of the fact we've already had 6 failed attempts this year. These airstrikes are appropriate action as it's the start to tackle the threat from ISIS, and stabilise our national security.

  20. Twitter reaction to Jeremy Corbyn avoiding Iraq question

    Labour leader Jeremy Corbyn was criticised by MPs for not answering whether he supported the UK's current air campaign against IS targets in Iraq. Here's a flavour of MPs' Twitter reaction:
