There seems to be an awful lot of people waiting in the long grass for Sunak - Jenrick, Braverman, Badenoch, Mordaunt, Shapps. I'm pretty sure Cleverly wants another chance at a leadership campaign too. Truss might not be able to launch another campaign but she'd definitely get behind anyone promising her a cabinet role. Then there is the MP's like Jenkyns that are just desperate to bring him down at all costs.
No wonder they don't get much done.
