Buckingham Palace has decided to maintain 'privacy' by not releasing details of Meghan Markle's alleged bullying.
Sources claimed last night that the Duchess of Sussex had threatened royal staff, but it would not be made available to the public.
A senior Palace source said: "We believe that those who participated in the review understood that discussions with an independent law firm would involve confidentiality."
"It is our duty to respect that privacy," the source said. "Objectives are satisfied because lessons have been learned."
The Queen hired a law firm to investigate claims Meghan fired two personal assistants in 2018 while other staff members began to tremble with fear.
Last year it was reported that the investigation's findings would be included in the Sovereign Grant Report.
