In terms of what seems to be an inflation reduced mini reshuffle, not really sure I get what Sunak is aiming for. Braverman getting sacked is fair enough - after the article was published ignoring most of the changes requested, he haf no real choice. No action looked weak, and gave Braverman a free pass for the future, while any later restriction on her, she could resign over, win her safe seat and look to be the next leader of the opposition.
Moving Cleverly who seems popular with Tory voters then works as a sop.
Bringing in Cameron has any number of risks, not least that in comparison Sunak looks inexperienced, while annoying a section of Tory voters. It's at least a novelty which might work as a distraction for the year.
It leaves the question of what Sunak's vision is as murky as before.
