Rishi Sunak needs a lot of things to keep his head above water at the moment, but let’s take one step at a time: for the duration of PMQs, he needed to not look rattled. He has three techniques that he rotates: smiling; dropping his Ts (to offset the tell, that all posh people get posher when they’re stressed); and ratcheting his cadence so that he gets faster and more joyful towards the end of a sentence, like a man selling you candyfloss at a very fun fair.
Unfortunately, he deploys all these at random, so he did a short peroration on the Post Office miscarriages of justice, grinning all the way through, and dropped the T in the middle of “important” but not at the end, creating the impression of a man who had forgotten what words meant and how to say them.
