The British Royal Family were jealous of Princess Diana's popularity at the time of her death, according to her ex-personal protection officer.
Ken Wharfe, a former Met Police officer, has accused the royals of being envious of Diana's popularity with the British public in 1997, but he believes her sons, Prince William and Prince Harry, have carried on her legacy.
He explained: "We now know Diana did change and modernise, whether we like it or not.
"What we see now today with William and Harry, in the way that they now conduct themselves as two leading royal figures, is so different from what royalty was in the 1980s.
"They are literally cardboard cut-outs of their mother's work, and 20 years on we are now speaking about their mother more than ever before."
Ken has written a book, titled 'Guarding Diana', about his overseas travels with the Princess.
And he claims her efforts to modernise the family has been reflected in her royal engagements, as well as in how she raised William and Harry.
Ken shared: "She would take them to Kensington High Street, take them to the cinema. They were great regulars of Bill Wyman's Sticky Fingers restaurant."
And of the Princess' popularity, Ken added: "The problem with Diana in this family is they could not deal with her popularity, they couldn't cope with it - basically they were jealous.
"They couldn't do it themselves and they wouldn't acknowledge just how good she was at it, this was a problem.
"Their attitude was 'this has been going on for a few hundred years lets not wreck it' - they weren't moving with the times and the couldn't honestly bring it round to say 'we've got somebody here who is changing its direction'."
