I would just return to the fact that there is not once ounce of proof as regards any poor behaviour on his part, indeed he's publicly denied it.
Although there are some undeniable facts:
Amanda Holden has gone on record with her allegations.
The relationship between Fern Britton and Phillip clearly disintegrated towards the end of Fern's tenure.
Fern and Phillip had a particularly acrimonious exchange on This Morning's 30th Birthday.
Fern's former agent has gone on record basically backing up Amanda Holden.
Veteran agent Mike Hollingsworth has gone on record claiming Phillip had a veto on the guests if he didn't like them.
What they are saying might be a load of nonsense, but the fact that prominent figures are making these claims is surely worthy of discussion on here, rather than it being shut down with "there's no proof"?
