If David Haye is not going to challenge himself and do the show properly, its pointless. He can workout in the jungle, and make sure he passes his tasks to get some good food. Maybe they will do a special challenge, that David Haye has to do! Just to get his specific food.
It will all be away from the cameras. I doubt he'll get special treatment on air or anything. Put It this way, Haye is a big name in England, and is recognised world wide (by Boxing fans anyway) If he entering the jungle is conditional on having access to some sort of gym on the sly. There is no way ITV would turn that request down.
If you are the compulsive betting type I'd put a tenner on Bristow to win- he always seemed like a laugh when he was a pundit at the darts. Haye needs to get off to a good start PR wise- I imagine he won't do many of the early challenges as Nadine Dorries will inevitably be voted to do them.
They'll have to listen closely, it won't be easy to understand what he's saying with a mouth full of kangaroo bollocks.
