I will give way in a moment.
As the Prime Minister said on Monday, there must be a full-spectrum response to deal with ISIL at its source in places such as Syria, Iraq and Libya. We know that ISIL is organised and directed from northern Syria. That is why the Prime Minister said during last September’s debate on taking military action in Iraq that
“there is a strong case for us to do more in Syria”.—[Official Report, 26 September 2014; Vol. 585, c. 1259.]
However, he recognised the reservations that some Members had, and we will not bring a motion to the House on which there is not some consensus. However, this is a new Parliament and it is for all Members to consider carefully how best to tackle ISIL, an evil caliphate that does not respect state boundaries.
Therefore, our position remains that we would return to the House for approval before conducting air strikes in Syria. The exception, as the House knows, is if a critical British national interest was at stake, or if there was the need to act to prevent a humanitarian catastrophe. We are also clear that any action we take must not provide any succour to Assad or his regime.
