Controversial broadcaster Piers Morgan says Harvey Weinstein believes he will eventually be forgiven by Hollywood.

The disgraced movie mogul, 66, has been accused by dozens of women of sexual misconduct, ranging from harassment to rape.

He has apologised for his past behaviour but denies all allegations of non-consensual sex.

Piers Morgan says he has spoken to Weinstein in a clinic in Arizona, where the producer is seeking treatment.

"He's a fascinating character. The apocalyptic symptom of the whole thing - the casting couch finally brought to judgement.

"I can't express the same level of shock as some people in Hollywood. Listen, this has been the system since Hollywood existed," Morgan said

He says he talked with Weinstein for an hour, and claims he's fighting.

"[Hollywood has] been a moral cesspit since the Twenties, and the idea that Harvey Weinstein is the only villain? Do me a favour.

"Look at Mel Gibson: ultimately Harvey believes he will be forgiven."

The producer is being investigated by police in London, New York and Los Angeles.
