Any kind of contact, payment and so forth would be very hard to disguise from an ongoing police investigation. Phone records, emails, social media etc etc.Fully expect that but don't write off the chances of the BBC or the Presenter paying hush money out.
I don't think anyone will come out of it well either reputationally or in terms of well being, regardless of the truth. The hares have been set running, as is the nature of these sorts of stories.
