According to a senior palace source, the details of the review were being kept under wraps in order to protect the anonymity of those who took part in the inquiry, during which current and former staff were invited to share their experiences of working under the Duchess of Sussex.
The source said that members of the royal faily and staff members had been made aware of the policy and procedural changes to the palace’s HR department, but they would not be shared publicly.
The investigation was launched by Buckingham Palace in March 2021, after it was alleged Ms Markle drove out two personal assistants. It was also claimed that staff were “humiliated” on several occasions.
Her lawyers denied the allegations when they were made.
At the time, the palace said any changes in policies or procedures recommended following the review would be shared in the Sovereign Grant report, which is published annually and documents royal accounts for the year.
The 2021-22 financial document, shared under the heading “Staff Report”, listed HR policies and procedures. However, it remains unknown which were introduced following the investigation carried out by a law firm and funded privately, thought to be a senior member of the royal family.
The report also outlines the royal household’s “Concern at Work” policy which encourages individuals to raise any concerns they may have about the conduct of others and sets out how issues can be aired, with the policy accessible to staff on the intranet site known as the Coronet.
The document also states: “Counselling and support are provided through the household’s long-established employee assistance programme and staff have been trained to be Mental Health First Aiders… Managers are trained to support, mentor and coach their teams and monitor their contribution…”
A senior palace source said: “I’m not going to comment on the changes that have been made to the policies and procedures – I’ll just say that the policies and procedures have been updated… the policies in relation to the Concern at Work apply to everyone who works within the royal household.”
The source later added: “Because of the confidentiality of the discussions we have not communicated the detailed recommendations. The recommendations have been incorporated within policies and procedures wherever appropriate and policies and procedures have changed.
“So all members of staff, all members of the royal family will be aware of what the policies and procedures are, the revised policies and procedures.”
