You are right up to a point, but I would hesitate to call Cummings incompetent. Never forget that it was he, and not Johnson or Gove, who masterminded the Vote Leave campaign, Johnson’s leadership campaign, and the 2019 General Election campaign. How on Earth he managed to sell that toxic buffoon as any kind of leader was, you have to admit, a work of genius. As you suggest, when the time comes he will do the same for Gove if he is allowed to. He is just about the only person of intellect in the government, apart from Rishi Sunak.
My only hope is that a public judicial inquiry is called before Johnson is removed. Then the whole sorry shambles of a Tory government will be swept aside, as most of them will be in prison for the criminal negligence that has seen more than 60,000 UK citizens die before their time.
