@jillongovt on the nail here.
Cummings’ disregard not just for constitutional convention (as Jill says) but for law generally was well-analysed by Collini in February. 
Those of us whose whole life experience, and profound belief, is that attention to the law, and legal scrutiny of decision-making, leads to better policy and better government need to recognise that he is simply on a different planet.
And Jill is also on the nail when she calls for responsibility for every single one of Cummings’ actions in government to be fixed on Johnson.
