WTF? So basically some people complaining that the unelected and unaccountable power behind the throne (Symonds) has got rid of the unelected and unaccountable power behind the throne (Cain and Cummings)?
If Cain or Cummings had any expertise other than how to manipulate people and break things, and Symonds was a Nancy Reagan-type astrology fan, then there might be a smidgeon of a reasonable complaint here.
As it is, she seems at least as qualified and experienced as the two men, and is even in a similarly easily terminated position. (Johnson very obviously doesn't considers himself in any way beholden to the women he shags, so it's not like she's blackmailing him with "preserving a marriage" against the good of the nation).
Symonds is basically another unelected No 10 functionary. If she won a battle over some other No 10 functionaries, so be it.
The really worrying thing here is that so many people speak as though Johnson is not the power, given he was the one elected...
