Former Scotland Yard officer Ken Wharfe says he believes Diana would have come to terms with her ex-husband marrying the now-Queen Camilla.
Wharfe told the Sun “part of Diana’s problem was that she naively 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.
“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.”
