In some ways this week, with the recall of Parliament and the UK’s tabling a UN resolution, seems like a fast replay of the run up to the 2003 invasion of Iraq. Many people’s attitudes to what’s happening are informed by the experience of Iraq, and reflect the view they took of that action ten years ago. Mine too.

So it may be no surprise that, although my legal argument is different here from that in the case of Iraq, and involves undoubted legal controversy, I think there is a proper legal basis on which the UK can participate in military action against Syria.
