Princess Diana's former royal bodyguard has said she would have eventually "accepted" Charles' relationship with Camilla if she was still alive

Ken told The Sun: "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.

"I questioned that at the time, but actually having listened to her, it made me understand Diana a lot better.

"And 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 31 August, 1997 - five years after she and then-Prince Charles split, before they finalised their divorce in 1996.

Two years after Diana was killed in a horror car crash Camilla and Charles publicly revealed their relationship.

Diana famously told of their affair in her TV interview with journalist Martin Bashir, saying: "There were three of us in this marriage, so it was a bit crowded."

Ken added if Diana not been killed, she and Charles wouldn't have restarted their relationship at any point.

But he says about how he is convinced she would have accepted it: "From my own experience in life, 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. She was very good at 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."
