The hit TV series charts the trials and tribulations of the Royal Family, with Series Four focusing on the events of the 1980s. This decade sees Diana Spencer join the royal fold and the series will delve deep into her marriage with Prince Charles as well as other personal struggles such as her battle with the eating disorder bulimia.
A royal expert has said revisiting the story of her life undoubtedly piles the pressure on for her two sons, William and Harry.
British royal biographer Penny Juror said that will be the case no matter if they watch the show or not.
She said: “After she died, they pleaded with people to let their mother rest in peace because they found it incredibly upsetting.
“I think it’s been really incredibly hard for them.
“Maybe they just put the shutters down and they don’t watch and they can close their ears to it all, I don’t know.
“But I really feel for them.”
Nick Bullen, editor-in-chief of True Royalty TV suggested he agreed with Ms Juror and that his sympathies lay with the two princes.
He said: “I wouldn’t want to watch my parents’ marriage play out on television.”

In 2006 The Queen was released, a film that follows the response to her tragic death on August 31, 1997 and in 2013 the film Diana was released about the last two years of her life.
As well as the two blockbuster films numerous documentaries charting her life and shocking death have also been published.
Netflix features three of the documentaries on its streaming site.
Over the years, Prince William and Harry have both opened up on how their mother’s death has affected them.
In 2017 Harry said that his mother’s death had “a quite serious effect on not only my personal life but my work as well.”
He also revealed he sought counselling to come to terms with her death and said he came “very close to a complete breakdown on numerous occasions”.
Prince William has also discussed the enduring impact her death still has on him.
He said: “I still find it difficult now because at the time it was so raw.
“And also it is not like most people’s grief, because everyone else knows about it, everyone knows the story, everyone knows her.”
