"She currently holds no official role in the Conservative Party or the government, yet consistent reports in the press suggest that Ms Symonds is taking a central role in running the country, without any authority or accountability to do so."
Well, quite, but hasn't that been the case with all the spouses of former PMs? Are we now going to pretend that those wives and husbands never spoke politics over dinner or that they never put in a good word for one of their friends when it came to getting a position in government? People without authority or accountability to the people have been bending the ears of politicians since politics was invented - it's old news and part of the game.
It would be a different thing if she was attending Cabinet or sitting in at official meetings such as COBRA, but as far as I know that is not the case.
