HOW sad to learn of the death of Cecil Parkinson’s eldest daughter Mary, 57, after years of addiction.

Friends say she never got over her father’s affair with his secretary, Sara Keays, with whom he had a daughter. As a report revealed last week, children are badly hurt when their mothers are cheated on. Despite his betrayal, Mary still worshipped her dad. And in the end, I suspect the trauma caused by these conflicting emotions proved unbearable.
