Everything about Victoria Derbyshire has been a farce and they are probably only saving face by not axing it. It seems to be an untouchable pet project of someone high up at the BBC.
Conceived by James Harding, Director, BBC News, sacked by Murdoch as editor of The Times, no broadcasting experience (this seems to be the norm now in the BBC) so he is unlikely to axe his own creation terrible though it is with an audience lower than any regional news programme.
