Jeremy will win DOI as he has all the credentials:
Used to be a ballet dancer, so will have nimble feet and rythem. Familiar face - and a bit of a looker - having been on Holby City, so will appeal to the many middle-aged women voters. 43 years of age - but says, "In my mind I'm still 20!" - so will be a tryer - which people like.
So I think he will have a head start in many areas - 4/1 - 9/2 lowish odds I know, but worth 2% of my bank! ;)
