The Royal Family is still below its targets to increase diversity among its staff.
In 2021, Buckingham Palace set a target to have 10 per cent of its staff be from an ethnic minority background by the following year.
However, the most recent Sovereign Grant Report, published in June this year, showed that figure is 9.6 per cent - still below the Palace's target.
In 2021 it was nine per cent and in 2020 it was 8.5 per cent.
The news comes as Buckingham Palace was plunged into a race row after comments Lady Susan Hussey made to a black charity boss during a visit.
Ngozi Fulani - who was questioned about her ethnicity by Lady Hussey - has called for institutional change within the Royal Family.
Ngozi, who runs a black women's domestic abuse charity in London, took to Twitter this week to share how the late Queen's friend who is also Prince William's godmother touched her hair and asked her "where in Africa she comes from".
Less than 24 hours later, the Palace confirmed Lady Hussey had stepped down following the remarks.
On Wednesday, Ngozi exclusively told The Mirror that she didn't want Lady Hussey to lose her job but called for institutional change.
She said: "I don't think it's fair that she (Hussey) should be hounded because the problem is bigger than her.
"It's the institution that needs to be looked at and I think much better am I than her, if I put her name out there, knowing that people are going to come after her or she's going to lose her job.
"That's not what I want. I want for women of African and Caribbean heritage to be able to go to these places, safely and for people who work for any establishment to be aware of racism. Because, 'I didn't know', is no longer an excuse.
"That's terrible, I'm not having that. I think it's a training thing rather than anything else.
"I'm not about someone being targeted, I'm about solutions. Let's find a kind solution than anything else."
She also told the Mirror this week that she felt blindsided by the comments, and that she just wanted to flee.
Ngozi said: "[What she did] was racism. Through and through. It was prolonged racism.
"The fact that it was just done in the open in front of people, on a day when we should be working towards violence against women."
She added: "I just wanted to leave, I felt very unwelcome. I've never lived anywhere else, I've only lived in Britain.
"So someone to come and tell me, someone, who has been in the royal household for her to kind of just insist that I'm not British.
"Those were not her words but that's the implication. I don't know how to process that."
Ngozi said she felt "very unwelcome" and "attacked' and the experience left her feeling like she had "been knocked back decades".
On Wednesday, a palace spokesman said in a statement that they "have reached out to Ngozi Fulani on this matter, and are inviting her to discuss all elements of her experience in person if she wishes".
Lady Hussey now wishes to meet Ms Fulani in person, and apologise to her directly.
Prince William has said "racism has no place in our society".
His spokesperson said on Wednesday: "I was really disappointed to hear about the guests' experience at Buckingham Palace last night.
"Obviously, I wasn’t there, but racism has no place in our society.
"The comments were unacceptable, and it is right that the individual has stepped aside with immediate effect."
The Mirror contacted Buckingham Palace for a comment in regard to its staff targets.
