I believe that it happened.The photo of the two of them is all you need to see to know something happened, he's got his arm around her, resting on her hip.
Most definitely not a photo o would expect of any grown man and teenager, especially ones not intimate with one another.
I cant in any way believe that any man in his 30s/40s would be in that sort of position with a girl young enough to be his daughter without being a sleaze bag.
Word of PA and this incident has been talked about for years. I remember hearing a vague mention about ot on the TV about 11 years ago!
He will never be charged because it happened whilst in the UK didnt it. No law broken according to RF. Morally, however most of us know that he's wrong in what he did. His family being who they are really is keeping many of his secrets hidden I'm sure.
