Oh dear
The War of the Waleses was an almost entirely one-sided war. Waged by a BBC employee who wanted the scoop of a generation.
Diana believed she was being briefed against because of Bashir
As PW says, that belief made everything so much worse during the divorce.
It has now been found in Court to be false, and deliberate manipulation. To an utter staggering extent (won't repeat them here, because some third parties have won considerable damages because Bashir used their names in the fabrications, but easily found on google)
Yes, it took in a lot of people, including the press, because everyone wanted to believe Diana. And look like they were "in the know"
No-one can point to any articles which hint at Diana as a "crazy wife" that are meant to have come from the Palace. The source for everything that suggests she had MH issues (potentially beyond unhappiness) are her own words, in the manipulated interview and the book written around the same time.
Charles always spoke of Diana with respect - no-one has been able to show otherwise.
So this smear moves on to "well everyone knew there was private briefing" - and the answer to that is, no we don't. We know Bashir fabricated it.
And no-one can point to anything in addition to that.
I don't think the full extent of what Bashir did is properly taken in to account.
