The face(s) and voice(s) of the UK are the Government and the Royal Family. Doing well then, aren't we?
Lots of organisations have public service remits/ charters or whatever. There's that sterling example of moderation, tolerance and high principles known as the Metropolitan Police, for one. The BBC should be held to the same standards as any employer - and that also means fair and proper disciplinary procedures after determining if there has been wrong doing.
It is just as well that "sleazy" behaviour and opinions, or not great moral standards isn't illegal - MN would probably have to shut down there would be so many posters in jail. If, and I repeat IF, this individual has done something which some here would disapprove of, that should make no difference to their position. If they have done something illegal, and knowingly so, then that should be treated as it would be by any employer given all the circumstances and arguments. Nobody should be tried by mob mentality.
