Meghan Markle is accused of "abrasive" behaviour towards members of staff and diplomats according to the explosive royal biography which is due to be released next week.
According to The Mirror, the book from Tom Bower titled Revenge: Meghan, Harry and the war between the Windsors claims the Sussex couple "bombarded their staff with demands for retribution and removal of the criticism.”
Meghan has been compared to Harry's mother Princess Diana, who was adored by the British public, and the Sussexes' have said that criticisms of Meghan were unfounded.
However, in the brand new book, it suggests the opposite, according to early exclusive extracts published ahead of the books release next week.
The latest damning claims from Bower allege Meghan and Harry fostered a bullying culture - allegations which have been investigated by Buckingham Palace.
The biographer has now suggested that Meghan was "abrasive" and demanding of her staff, as well as being "inflamed by the slightest criticism."
He wrote: "Meghan was allegedly abrasive towards her four female staff and even towards the local British diplomats."
"According to one report, Meghan allegedly threw a cup of tea into the air. Her anger may have been partly fuelled by Harry.
"Every night he trawled social media, searching for snide comments on the internet. Every morning he and Meghan turned on their phones to surf the internet."
Lawyers on behalf of Meghan have denied all claims of bullying towards palace staff or aides.
Complaints against Meghan emerged in March 2021, hours before the couple's explosive interview with Oprah Winfrey was broadcast, in which Meghan accused the Royal Family of "perpetuating falsehoods".
A probe into bullying allegations was announced by the Queen after the claims emerged, and was concluded in June, but Buckingham Palace did not make the report's findings public.
Instead, they said that recommendations arising from the investigation has led to improved policies for royal staff and affected change in their procedures.
New implementations included encouraging staff to be honest about "inappropriate" practices or actions.
A royal expert called Richard Fitzwilliams told the MailOnline that Buckingham Palace's refusal to publish the report could be viewed as an "olive branch" to the Sussexes.
