PRINCE William and Kate Middleton were met by pockets of booing as they took in a basketball game during a visit to the US.

The pair’s three-day trip has been overshadowed by the growing race row engulfing the future King’s godmother which has left the monarchy accused of being institutionally racist.

Lady Susan Hussey has resigned from her role in the royal household and apologised after she repeatedly questioned Ngozi Fulani, a prominent black British-born domestic abuse charity boss, about where she “really came from” during a Buckingham Palace reception.

A Kensington Palace spokesman told reporters in the US that “racism has no place in our society”.

Fulani told The Guardian: “It’s tragic for me that it has ended that way. I would have preferred that she had been spoken to or re-educated.”

In a separate interview with LBC, she confirmed that “nobody from the palace has spoken to me” but that she would be “happy to have a conversation to bring about a positive solution”.

She added: “To be honest I wish that the lady could be spoken to and know the damage she has caused and preferably not be front-facing.”

“But for her to resign, that has nothing to do with me. I don’t feel good about that. She’s an elder and in my culture we respect elders.

“Conversations need to be had with the relevant people so this kind of thing doesn’t happen again.”

The palace described the remarks as “unacceptable and deeply regrettable”.

The Prince and Princess of Wales took in the match between the Boston Celtics and Miami Heat.

As they stood for the national anthem, they were subject to small pockets of booing around the arena when introduced by a stadium announcer and shown on the big screen.

The Boston Celtics’ name was inspired by the Original Celtics, a well-known basketball team that had been created by Irish immigrant in New York in the early 20th century.

Other fans in the crowd were heard loudly chanting “USA, USA”, when the pair appeared on screen.
