The resignations of Munira Mirza and other aides should galvanise Tory MPs to do what they must now do
In writing about politics you can either try to explain what you think is happening or you can say what you think should happen. Right now, there is a complete convergence between the two. Boris Johnson’s premiership is on the slide, irreversibly so. The question is not whether Johnson will go. It is when and how – and what will come after.
Simultaneously it is increasingly plain that Johnson should go. Some take this view for partisan reasons or because Johnson’s personality appals them. Fair enough. But that’s not my argument here. There is also an extremely powerful Conservative case against him remaining. In the end, this will be decisive, because he will only go only if it is in the Tory party’s interest; no one else’s.
