A PP had it, upthread. The contents of the actual report are not an indictment of Morgan, despite the demented crowing emanating from his column and those of his colleagues in the DM. As ever, they pointed out that context is everything, and in the context of their programming, Morgan's vitriolic, obsessive outpourings were robustly challenged. Job done: and that's thanks to his co-hosts not to him.
Storming offset because you don't like what someone's said is grossly unprofessional. ITV are, IMO, quite right to say they won't have him back. Legalities aside, they have the right to set their own standards.
As to the legal side, of course it's not only necessary, but crucial, that any society with pretentions to democracy go all out to protect its free press. The Windsors already have far too much leverage over their rosy if dullsome (and wholly contrived) image in the press as it is. IMO, it's a pity more of them are not opened up to the same sort of scrutiny, especially in relation to one cossetted, miscreant son of HMQ. But it seems they've reserved that high-powered spotlight of attention for two members in particular. Funny, that.
