I think Gove is likely to take over - he has been groomed by Murdoch for quite a while, who never wanted him tainted by the prospect of a no deal brexit - because how ever fervent they all seem about no deal and however much money they make, they know the impact will be devastating for the majority of the population and that people will be very, very angry.
Johnson was the easy answer for that. He is so arrogant and lazy they knew he would love the chance to be big boss but wouldn’t interfere in the no deal plan as he is too lazy and incompetent to implement any actual policy. Once no deal has been pushed through combined with the post covid implications he will be poison and removed from office for the greater good with Gove coming to save the day.
For all his many faults Boris is charming and good fun (as long as you don’t trust him when your back is turned) but Gove is almost universally loathed.
He is far more intelligent than boris and far more ruthless.
He will keep his master Murdoch happy but will be far more involved in actual leadership than Johnson.
He and Cummings together could inflict a level of austerity and misery on the workers, the poor, disabled and vulnerable of this country that will make Victorian workhouses look like 5 star resorts and there will be no EU laws or courts to protect us.
This has been the plan all along. Brexit vote started as a vanity gamble by Cameron but was quickly hopped on by those who thought the UK was getting far too close to being a society where the rich and privileged were losing their automatic entitlements.
