I don't know how Jeremy Vine has managed to replace Matthew Wright who, although I found him quite overbearing at times, was at least engaging and could never be described as bland.
I think JV is rather insipid and not at all suitable for a live - and often very lively - programme discussing current issues.
I had guessed MW would be leaving because for the last year or so his absences have been much more frequent and there have been several presenters taking over for days or weeks at a time. My own favourites were Anne Diamond, Penny Smith and Matt Barbett. I don't even recall Jeremy Vine doing one of these stints. It's inexplicable how he has got the job.
I am so sorry David Dimbleby is leaving Question Time. I know some people don't like him but I have always thought him to be a good humoured and astute chairperson. I suppose it was to be expected as he is, I think, in his late 70's or early 80's and has been doing the programme for some time.
I like Richard Osman too - a very pleasant and intelligent man. I also like James O'Brien, though he may be thought too abrasive for QT. I think Nicky Campbell is very good too. Why not a woman though? Anita Anand who hosts Any Answers on Radio 4 and has shown herself to be very clear headed, knowledgeable and courteous - at the same time as analysing and sometimes challenging the rationale underlying contributors' opinions - is I think worth considering.
