I suspect that it is less about being Tory, but about JD-P being a normal intelligent woman with real life experience and a desire to contribute constructively to society.
She was good pre-Boris when she held a ministerial portfolio that included teenage mental health. (Indeed I wonder what happened to her promised study on ROGD.)
We have some good women, including in the HOL. JD-P, Baroness Nicholson, Baroness Tanni Grey, Baroness Kishwer Falkner, Liz Truss, Kemi Badenoch, Rosie Duffield.
Being GC is not an obvious career move for a politician. I would prefer to see more in all parties whose politics come from a place of honesty and common sense, even if I, with my different background and experience, disagree with them.
I hope JKR can be given what is needed to sit in the HOL.
