Unwise’ is a strange choice of words, and quite derogatory to MM.
I wouldn’t have used the word ‘unwise’ at all. Just would’ve said a consensual relationship began when the person involved was 18.
PS can’t sugar coat it, he got young lads in for work experience (never girls) and this one in particular (maybe others too who knows) became a target. He held a position of power over MM so it’s totally grooming.
Glad he quit ITV, next out is HW for enabling PS. She had opportunities to advise PS or else inform ITV bosses. She did neither, she needs to go!
