A royal source did admit “there were some recommendations which came through for changes in our policies and procedures” and the HR guidelines would be “regularly reviewed”.
The claims were made shortly before Harry and Meghan’s television interview with Oprah Winfrey was broadcast in which the couple accused an unnamed member of the royal family of being “racist”.
Buckingham Palace has released the annual Sovereign Grant report - the money which comes from the public purse through profits from the Crown Estate.
It revealed that the Royal household had not yet met its own targets for the number of staff it employs from ethnic minority backgrounds.
The palace is committed to a target of 10% by the end of 2022.
The latest figures show that 9.6% of household staff are from ethnic minorities.
A senior aide said they had hoped to have exceeded the 10% target at this point but remained hopeful it would be achieved by the end of the year.
Clarence House, which runs the office of Prince Charles and Camilla, said 10.6% of its staff are from minority communities.
The equivalent figure for Kensington Palace, Prince William and Kate’s office, is 13.6%.
