The political weather has changed at Westminster. Tory MPs now have a spring in their step in a way that they haven’t had since the snap election went so wrong. By contrast, the Labour benches look glummer than they have in a while.
Tory MPs might be exaggerating how much things have really changed; several of them are currently demonstrating that the Conservative party really does only have two modes, panic or complacency. But a couple of things have shifted in the last few weeks.
Jeremy Corbyn’s reaction to the assassination attempt on Sergei Skripal has reminded Labour moderates of why they were so opposed to Corbyn in the first place. Whether this sense leads to them actually taking any concrete steps remains to be seen. But what does seem certain is that Corbyn is back to where he was before the election: he will have to make his case in the face of continued criticism from his own side.
The second thing that has changed is that there is now a critique of Corbyn on national security that doesn’t require you to know any history to understand it. His handling of the Salisbury attack has provided a real time demonstration of what’s wrong with his foreign policy worldview.
