Prince Harry slammed the phone down on Prince William after being confronted with witness statements in a Meghan Markle bullying probe, a French TV documentary has claimed.
In turn, William reportedly became so angry at his brother’s insistence on protecting Meghan from criticism that he jumped in a car “towards Kensington Palace to go and confront Prince Harry ”.
French channel BFM TV detailed the alleged drama in an investigative documentary called “Red Line: William and Harry, the enemy brothers”.
The series claims that exasperated staff resigned from the Royal Household as soon as they could and set up a WhatsApp group called “The Sussex Survivors’ Club”.
The documentary is due to come out next week, on the 25th anniversary of the death of William and Harry’s mother, Princess Diana, in a Paris car crash on August 31, 1997.
It alleges the Duchess of Sussex, 41, bullied staff while living in Kensington Palace, with Harry, 37.
An email in the autumn of 2018 written by Jason Knauf, former communications secretary to Harry and Meghan, to Simon Case, the Duke of Cambridge’s then private secretary, first brought the allegations to light.
Mr Knauf claimed Meghan had “bullied” two female personal assistants “out of the Household”.
One of the unnamed staff members is referred to using the letter Y.
The documentary claims: “The Duchess seems intent on always having someone as a target. She’s bullying Y, and seeking to undermine her confidence.
“We have had report after report from people who have been witnessing this unacceptable behaviour towards Y.”
The Knauf email reads: "I am very concerned that the Duchess had been bullying and harassing two personal assistants, to the extent that she provoked their resignation during the course of the last year."
The documentary narrative continues: "During 2018 there was indeed a spate of resignations among Meghan Markle’s team.
"Former members have even set up an informal group that they called between them, the Sussex Survivors’ Club. Some of them still remain traumatised."
Pierrick Geais, a royal author who has written a book about the Duke of Cambridge, told the programme: "William, who already didn’t like his sister-in-law very much, became furious. He called Harry directly, and Harry slammed the phone down.
"Harry didn’t want to know anything, and so William jumped in a car towards Kensington Palace, where he was going to confront Prince Harry."
Valentine Low, The Times royal correspondent, is also quoted in the documentary saying: "There was a person who was so terrified by a conversation she was about to have with Meghan that she said, 'I feel sick'. Some of these young women have been broken."
Buckingham Palace announced earlier this year that it would not be releasing details of a legal enquiry into Meghan’s bullying, and this led to accusations of a Royal cover-up.
Meghan herself has yet to comment on the scandal, despite just launching a new podcast focusing on female stereotypes.
She and her husband have “stepped back” from Royal duties and now live in Montecito, California, with their two young children.
The couple are due to return to the UK in September, when Meghan is due to speak about female empowerment at a conference in Manchester.
The Mirror has approached The Cambridge's and the Sussex' organisation Archewell for comment.
