'Man has affair at his work' is not news, and not in the public interest. We don't know (and it's none of our business) whether his wife was fully aware of the affair, and it is between them in any case. Rylan was famously unfaithful to his husband and continued as a presenter, and there will, by the law of averages, be numerous others who have done, and are still doing likewise.
'TV presenter is gay' is not news either. Again, Rylan is out and proud, and is very popular, rightly in my opinion.
'Man who is portrayed as a family man on a family show and turns out to be less wholesome than he pretends' is incompatible with being a presenter of This Morning, in the same way as Angus Deayton could no longer present a show that satirised people's sexual peccadilloes after being caught out himself.
'Older man is accused of grooming a boy and having sex with him at the same time as giving him sought-after opportunities in show business' is bringing the reputation of ITV into disrepute.
Coupled with the fact that other presenters are on record as saying that Schofield is arrogant, haughty, unpleasant and rude, that his popularity was in decline after queue-jumping at the Queen's lying in state, and that other rumours have been circulating about him for years, his position was untenable. If he'd stayed, someone would have come forward with more damaging information.
I caught the first episode last night and found it self-indulgent and tedious. I can't bear PS though, so wasn't disposed to be sympathetic.
