I have always enjoyed Fiona Bruce's shows on TV (mainly - Antiques Roadshow; Fake or Fortune).
However, since seeing her on Question Time with Diane Abbott it has shown me another side of her: where she stands politically and what she thinks of those who would disagree with her. Her enjoyment at putting Diane Abbott straight/down was quite plain to see and judging from the things she said in the warm up as reported, she made her dislike, even contempt, for Diane Abbott quite clear to the public. (David Dimbleby, although he may well be politically on the same side as Fiona Bruce, was always professional and trying to be fair)
I find I can't look at Fiona Bruce now without thinking of her using her powerful position to hurt Diane Abbott. She has, for me, sullied herself.
