Buckingham Palace hasn't done enough to increase diversity among its staff.
That's according to a senior royal source, speaking on condition of anonymity.
In its annual report detailing the queen's taxpayer-funded spending, the palace said on Wednesday that only 8.5% of its staff were from ethnic minorities - the first time it's given such a breakdown.
And it aims to have 10% of workers from ethnic minorities by the end of 2022.
The palace has come under fire from Queen Elizabeth's grandson Prince Harry and his wife Meghan for the way it deals with race.
Including the explosive U.S. interview with Oprah Winfrey in March, when the Duchess of Sussex accused an unnamed member of the royal family of a racist comment.
Harry's elder brother William publicly denied that the family were racist, but the queen said the issue was concerning, and would be addressed.
In the run-up to the interview, the palace also said it would review staff allegations of bullying by Meghan.
She said she was saddened by the "attack on her character".
