Rouass is half-Indian/half-Morrocan so presumably looks a little "like a Paki" at the best of times. About 15 people heard this remark and before long the BBC thought police had dived in. The case was somewhat reminiscent of Carol Thatcher, who said a black tennis player's hair looked like, "a golliwog's".
The outcome however was very different.
Anton Du Beke apologised and that was the end of the matter as far as the BBC was concerned. Carol Thatcher apologised and was fired.
Why the different standards? One suspects that Carol was being punished for the sins of her mother.
