Syria. MPs to argue about the stable door after the horse has bolted – or, rather, is back inside.

The Prime Minister faces a difficult afternoon – but will be aided by the unwillingess of Tory backbenchers to line up with Jeremy Corbyn.

WATCH: Cable – It’s “very important for the Prime Minister to build a consensus” on Syria, “which she hasn’t done”

The Liberal Democrat Leader warns that May could come to regret not holding a Commons vote if the operation goes “very badly pear-shaped”.

WATCH: Lidington – “We are neither shutting our eyes nor holding our noses” to Assad’s other war crimes

As well as punishing the use of chemical weapons, “we are seeking to hold Assad to account at the UN Security Council…despite the fact that he is protected by Russia”.

WATCH: Thornberry – “It cannot be Donald Trump and a couple of allies deciding unilaterally” on Syria

“We have been here before, when we have not had clear evidence about weapons of mass destruction.”

WATCH: Johnson – “This was the right thing to do – to deter the use of chemical weapons not just by Assad but around the world”

“People around the world are looking now and saying ‘finally, someone stood up against that’, and the world said ‘enough’ to the use of such weapons.”

Our survey. Tory members support military action against Assad – up to a point

Three in four support some kind of action. However, three in five appear unwilling to risk members of our armed forces losing their lives.

The UK could set a lead by announcing that it will dedicate a fixed or minimum percentage of the aid budget to fighting sexual and gender based violence.

If there is a Commons vote on Syria, the willingness of Labour rebels to support action could make all the difference

In 2013, Conservative rebels joined with Labour to sink Cameron’s plan. Might the reverse happen five years later?

And: should the Government have the power to do so without a preceding Commons vote?

Iain Dale: There’s a glint in Harman’s eye as she watches the Speaker’s chair

Plus: For and against bombing Syria. For Andrew Neil. Against Andrew Adonis. And: not an erection in sight.

Syria. May’s calculation and the dangers of a May miscalculation – to others and to her

She will be feeling a hand of history on her shoulder, and wondering if the other holds a knife at her back.

Daniel Hannan: Corbyn’s first instinct in a national crisis is to treat it as a way to attack the Tories – much to Putin’s satisfaction

Ask one question: In what conflict has Jeremy Corbyn ever been on Britain’s side? He always finds a way of blaming the world’s problems on the West.

Ben Roback: The West’s response to Syria is in Trump’s hands

The atrocity demands a response, but will the President favour international diplomacy or military action?

Let’s suppose missile strikes target the Assad regime. But afterwards chemical weapons are used again in Syria. What then?

Reports this morning suggest conflict within the Government and hesitation in America. And no wonder.
