Prince William on Thursday spoke out in defence of the British royal family after his younger brother Harry and wife Meghan Markle accused them of racism in a bombshell interview watched around the world.

“We’re very much not a racist family,” William told reporters during a visit to a multi-racial school in a deprived area of east London. He is the first royal to personally respond to the allegation during his first royal engagement since the Oprah interview.

The Duke of Cambridge, son of heir-to-the-throne Prince Charles, added that he had yet to speak to Harry in California since the interview first aired in the United States on Sunday.

“No, I haven’t spoken to him yet, but I will do,” he said.
