LONDON — The late Queen's lady-in-waiting Lady Susan Hussey has apologized and resigned after she repeatedly asked a black British charity boss where she was "really" from.

Ngozi Fulani, a charity founder, was questioned about her background at the charity event at the palace on Tuesday.

Ms Fulani said she was "totally stunned" by Prince William's godmother's comments.

The palace described the remarks as "unacceptable and deeply regrettable".

A spokesperson for Prince William said "racism has no place in our society".

"The comments were unacceptable, and it is right that the individual has stepped aside with immediate effect," they said.

Lady Hussey, 83, was a close confidante of the late Queen and accompanied her at the funeral of the Duke of Edinburgh last year.

She was a key and trusted figure in the Royal Household for decades, and part of her latest role had involved helping to host occasions at Buckingham Palace.

Ms Fulani, in an interview with the Independent website, said the issue was "bigger than one individual. It's institutional racism".

"I was in shock after it happened and anybody who knows me knows I don't take this kind of nonsense," she said.

"But I had to consider so many things. As a black person, I found myself in this place where I wanted to say something but what happened would automatically be seen as my fault, it would bring [my charity] Sistah Space down.

"It would be 'oh, she has a chip on their shoulder'."

Ms Fulani said she did not want to see Lady Hussey "vilified".

An eyewitness to the conversation, Mandu Reid, told BBC News that Lady Hussey's questions had been "offensive, racist and unwelcoming".

The leader of the Women's Equality Party said she had felt a "sense of incredulity" about the exchange in which Ms Fulani was interrogated about where she was from, even though she had already explained she was born and lived in the UK.

In its statement, Buckingham Palace said: "We take this incident extremely seriously and have investigated immediately to establish the full details.

"In this instance, unacceptable and deeply regrettable comments have been made. We 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.

"In the meantime, the individual concerned would like to express her profound apologies for the hurt caused and has stepped aside from her honorary role with immediate effect.

"All members of the household are being reminded of the diversity and inclusivity policies which they are required to uphold at all times."

Ms Fulani was at the reception at Buckingham Palace on Tuesday representing the London-based charity Sistah Space, which supports women of African and Caribbean heritage across the UK who have faced domestic and sexual abuse.

Along with 300 guests, she had been invited to the event, where the Queen Consort, Camilla, had warned of a "global pandemic of violence against women".

But afterwards, Ms Fulani described on Twitter how the royal aide moved her hair aside to see her name badge, and then challenged her to explain where she was from.

In the post, Ms Fulani referred to the palace aide only as "Lady SH".

But Ms Reid confirmed to BBC News the person who had made the remarks was Lady Susan Hussey, having seen her name badge. Neither Buckingham Palace nor the charity named her. — BBC
