The Times long read is actually quite short today - that's a good thing!
But there is a section on the Simon Clarke amendment to the Levelling Up & Regeneration Bill which was backed by Johnson & Truss - essentially breaking with convention and not offering straightforward loyalty to the new PM.
No surprises there but goes on to say -
Johnson’s challenge in particular represents the beginning of a new phase in their relationship. Until now the former prime minister had been publicly supportive of Sunak, but allies say he will become more robust in his interventions in defending what he sees as his legacy issues, including levelling up.
His supporters are convinced that Sunak will fall and that Johnson will replace him, with the May local elections seen as a focal point. “We’re not going quietly,” one backer of Johnson said. “They won’t be able to get any legislation through.”
All a bit similar to the difficulties Theresa May faced with the same characters blocking & agitating. It's going to be horribly divisive and terrible for the country.
