Former Scotland Yard officer Ken Wharfe says he believes Diana would have come to terms with her ex-husband marrying now-Queen Camilla.
Wharfe told The Sun newspaper that "part of Diana's problem was that she naïvely believed that the relationship with Camilla would fade away".
"But let's be honest, Camilla was there from day one. Camilla from my time, I went there in the mid-1980s, was very much the discussion at the time.

"And (with) Diana's openness – she felt it necessary to give me the complete low down of the relationship.
"She naïvely believed that it would end. There is no doubt in my mind that Diana did love Charles. I mean, she said that to me repeatedly."
Diana, who was killed aged 36 in a Paris car crash on August 31, 1997 – five years after she and then-Prince Charles split, before they finalised their divorce in 1996.
Two years later Camilla and Charles publicly revealed their relationship.
Diana famously told of their affair in her TV interview saying: "There were three of us in this marriage, so it was a bit crowded."

Wharfe is convinced Diana would have eventually accepted it.
"You move on and you change, you mellow slightly, and you deal with situations in a much calmer way.
"And I'm sure Diana would have done that.
"Time, as everyone says, is a great healer. Diana was angry with the Prince of Wales, angry with her circumstances, angry with Camilla, angry with everybody.
"But you know you know, things heal. And as time progressed, she would have been in her 60s now, she would have accepted."
