A Balmoral supervisor unveiled the moment the marriage of Charles and Diana began to 'deteriorate' during the Scottish estate, not long after their wedding in 1981.
The claims are made by an unnamed Gilly (a hunting and fish expert) in the new book Yes, Madam: The Secret Life of Royal Servants of the Royal Author Tom Quinn, which will be released next month.
In an extract from the book, seen by Femail, which has describes accounts of Royal Servants over the years, the guide shared how the late Princess of Wales Balmoral hated.
Anonymous expressed the supervisor that Diana's hatred against the Scottish home came out of her boredom with the traditional outdoor activities – despite growing up in nature and from a family that loved hunting and fishing.
He added that she preferred the city and did not like country sports – a recognition that completely shocked the then Prince of Wales, who was an avid fox hunter.
King Charles was fond of stalking as a young man and after his first murder apparently was lubricated with the blood of the first fox and the first he recognized and killed according to the royal tradition.
But Diana was less impressed and could not throw herself into the activity and it was that – not her husband's unfaithfulness – that would have undermined their marriage from the start.
The insider said, “That was, I think, the beginning of the deterioration of their relationship, whatever people say that it was completely about the other woman!”

In the meantime, Diana's boredom led to a number of brutal jokes to kill the time, according to the book.
During an outing while she accompanied her husband about one of his favorite activities, she got her boredom how she got better from her and she teased the group of enthusiastic fishermen, the guide claimed.
De Gilly remembered: 'I remember that once she was quietly looking at all the casting and discussions about which flies to use.
'She looked a bit bored and when everything fell silent, she shouted against Prince Charles:' Honey, it would not be easier to just use a net! “.”
The then prince and princess of Wales' different hobbies apparently became a constant point of dispute in their marriage.
In nine letters written by Princess Diana in the early years of her doomed marriage to Charles, who were auctioned in June, she told Maud Pendrey, the former housekeeper of her family, how her honeymoon was a 'huge success' and said she and Charles had a 'glorious time'.
But her letters hid a sad truth and Penny Junor, author of the Duchess, wrote that the differences of the couple on their honeymoon became pretty grim.
While the future king had in mind swimming, reading, painting and writing thanks, Diana had expected to chat.

“He had taken his watercolors, some canvases and a stack of books by the Afrikaner Mystic and writer Laurens van der Post, of which he had hoped he and Diana could share and then discuss in the evenings,” wrote Mrs. Junor.
“Diana, however, was not a great reader. She hated his miserable books and was insulted that he might have preferred it to bury his head in one of them instead of sitting and talking to her. She also heard him at his donkey for hours, and they had many flaring rows.
'One day, when Charles painted on the Verandadek of Britannia, he went to look at something for half an hour. He came back to discover that she had destroyed his painting and all his materials. '
In 2018, a Bombshell Royal Biography of Royal Reporter Robert Jobson Prince Charles unveiled that his decision to call off his marriage to Diana.
Although he realized that he and the daughter of the Aristocrat were incompatible, he felt powerless to do something about it. The breakdown of the engagement would have been cataclysmic, “he said.
Years later and still disturbed by the tragedy of marriage, he weeped tears of frustration when he told friends: “I wanted to desperate from the wedding in 1981, when I discovered how terrible the prospects were during the engagement.”
Other Bombshells revealed in the latest book by Tom Quinn include the size of King Charles mood.
The biography reveals that the king 'will lose his patience in a fraction of a second' If his very specific requirements are not met, insiders have claimed in an upcoming book.

Insiders explained that Charles and Queen Camilla always treat their staff well, but that the king is susceptible to 'small eruptions of irritation'.
Charles, who is generally known to have a mood and is rather in public limited about his pens that does not work, has very specific requirements for how tasks are performed.
It was said that the monarch made a fuss if he had not given the 'right tea cup' and also had opinions about how his toothpaste was placed on his brush.
In an extract from yes ma'am: The secret life of royal servants who were seen by Femail, a servant remembered: 'Charles and Camilla treat their staff well, but you always feel that they would not fly more without an airplane than you invite tea with them.
'And Charles has few outbursts of irritation with his staff – perhaps he may not have exactly the right tea cup, perfectly polished shoes and toothpaste neatly on his toothbrush on exactly as he likes it.
“He loses his mood in a fraction of a second, but usually regrets it quickly.”
