In the memoir, Earl Spencer writes of his sister’s troubled marriage – claiming a friend of Diana’s had told him that on the eve of their wedding in July 1981, Prince Charles had told her he was “very happy to marry her, but… not actually in love with her”.
Things became “very difficult indeed” in the marriage early on, Earl Spencer writes, adding that he is “sure that both spouses despaired of the other at times”.
He now believes his sister had attention deficit hyperactivity disorder, external (ADHD), and as part of her condition suffered from Rejection Sensitive Dysphoria – describing the latter as an “intense emotional pain in the face of others’ rejection or criticism”.
In her later years, he writes, Princess Diana considered taking her own life on more than one occasion but love for her sons “stopped her from going further”.
The former press secretary to Queen Elizabeth II described the latest claims serialised in the Daily Mail of Charles sounding “giddily elated” as “hogwash”.
Dickie Arbiter, who was press secretary to the late Queen at the time of Princess Diana’s death and funeral, told Newsnight that Charles was “devastated at the time” and that “it’s not in his character”.
“There’s no way he could have ever said anything like that. Charles Spencer is just talking hogwash,” he added.
Asked how the latest allegations would be affecting the King, Arbiter added: “He’ll be exasperated, but he’ll get on with the job.
“It will trouble him because this book is going to come out, it’s going to be serialised, and what more is going to be revealed?”
Amid the royal drama, Prince Harry, the Duke of Sussex, attended the inaugural Invictus Spirit Awards in Greenwich on Thursday evening.
In his first public appearance since moving back to the UK, Prince Harry posed for photographs for the press and selfies with veterans, before delivering a speech.
