Chairman/front man? I don't know but I certainly don't think you are being thick. Kelvin isn't the money here is he, isn't he just the front man ?
Still doesn't explain why he would like to be a 'front man' to an unknown Russian, that he doesn't have any connection with. Plus, as I said previous. He still needs to find a buyer here first, he can't just step down, can he? His consortium has still put a lot of money in, this will be lost if he walks away.
