My information did not come from Wikipedia but from interviews given by Sara Keays to the Guardian and the Independent, plus reports of the hearing and the financial matters.
I am not sure how Cecil Parkinson's abhorrent disregard for Flora is able to continue after his death. He provided for her all his life, and made provision for her after he had died. He did not wish for personal relationship, and I think he was wise; you may not. This is a child who would not, because of her disabilities, been aware or interested in, the circumstances of her parentage unless her mother had specifically told her.
The more I read about Sara Keays the less respect I have for her. She was a willing partner in the affair despite knowing Parkinson was married and had young children, and in the conception of her child; both were equally to blame, and both paid for it. Parkinson supported Flora financially, all his life, far more than many divorced fathers do.
Keays has wreaked vengeance on him and tried to wreck his marriage and his career, neither succeeded. I feel she has suffered more, because she cannot let go.
