Whole situation is getting weirder and weirder. The young person at the middle of all this has now issued a letter via a lawyer (and a well known lawyer too) saying they'd contacted The Sun prior to publication denying anything inappropriate took place and that he and his mum were estranged.
Then the step-dad said they'd put all the allegations to the BBC for over an hour when a few days ago the parents claimed they hadn't spoken to anyone from the BBC.
God knows what the truth of all this is but I don't think its as straightforward as it first appeared.
