Whilst I've got no love for Sunak, its clear that this is a hatchet job - probably from within the Tory party.

As I mentioned some time ago, he wanted to be PM and he didn't want to wait for the opportunity. Mud was slung at #10 over partygate - and this mud is being thrown back now.

Sunak's political career is hanging by a thread, if it isn't already over.

One thing BJ is good at is riding through the rough moments and diverting attention away from him when he most needs it. And its very possible he's now diverting the negative momentum away from him and towards Sunak.
