I didn't think him ill tempered , he couldn't 'do' charm for tv , the attacks by the press which switched from labour to Cameron such as the criticism of not writing clearly because he only had sight in one eye , he refused to discuss his family or do camera poses with them for the press.
He didn't speak publicly of the death of Jennifer for ten years, Cameron emailed his party about the death of his son before the little chap was buried. He refused to speak to the Sun when that rag discovered little Frazier had cystic fibrosis, he asked it not be made public and was distressed when his request was ignored. He is that quite rare politician, doesn't do charm does honesty
