Who is having a bad summer now? David Cameron faced cries of resign as he lost last night’s vote. Speaking for many, Michael Gove turned around and shouted “disgrace, disgrace, disgrace” up at Tory backbenchers, accusing Labour of giving “succour to Assad” afterwards. Guido is told Shadow Defence secretary Jim Murphy was involved in a heated four-letter exchange on the floor of the House after the vote.

Unbelievably Justine Greening and junior Foreign Office minister Mark Simmonds failed to vote. A spokesperson for Greening claims the pair were not aware the vote was taking place. Astounded government sources stress there is no way they could not have known. Greening will do well to survive this.

One Tory MP shares his analysis with Guido:

“Completely self-inflicted wound. Failure to prepare the country or MPs for military action. Case was never made. Never has been a majority for military action so why push for it without prep? PM has so many enemies in the party, they saw this as the perfect opportunity to humiliate him. I still don’t think he understands this. Number 10 thinks its barbecues are the answer but it makes no difference. This could be very dangerous for the PM in the run-up to conference.”

Cameron has arguably never been weaker…

UPDATE: Greening is saying that she was not aware the vote was taking place because there wasn’t a second bell, not that she didn’t hear the bell.
