So that begs the question as to who should now replace her. It won't be an easy decision for the THIS WEEK production team to make as few of her 'deputies' have made much of an impact. I quite liked the Hazel Blears/DD combination but I doubt whether there will be much appetite to axe Michael Portillo too.
Tessa Jowell would have been great, but she's in the Shadow Cabinet, as is Caroline Flint who was quite entertaining when she took over. Oona King is a possibility, as she was also good when she appeared one week.
I think they key thing is that whoever takes over has a sense of humour and has an incisive insight into Labour politics. Diane met the first criteria but not the second.
The only names from the Labour Party I can suggest are Ann Clywd, Fiona Mactaggart,
Of course, it doesn't have to be a serving MP. It could be an ex MP or a peer.
Who would you suggest?
* UPDATE: Dawn Primarolo is a deputy speaker, a fact which I had forgotten!
