King Charles III pals and close aides launched a smear campaign against Princess Diana, says expert.
Patrick Jephson claimed the monarch's staff put out a false picture over the former Princess of Wales mental health.
King orchestrated a "systematic" smear campaign against his ex-wife, which made her life "hell".
The conversation was far from "casual gossip" and was a "systematic campaign" to depict Diana as a "bit crazy."
Mr Jephson defends: "Considering the life she lived, considering the pressures she was under, she wasn’t just sane, she had a kind of ability to restore sanity to crazy situations."
Earlier, expert Phil Craig claimed: "Diana is absolutely at her best: she's charming, she's funny, she's slightly flirtatious, she's absolutely on top of her brief, she's talking very eloquently about politics, and about world leaders."
