Prince William, Duke of Cambridge

Prince William denies Britain's royals are racist after Meghan Markle, wife of his younger brother Harry, said one unnamed member of the family had asked how dark their son Archie's skin might be.

On Tuesday, Buckingham Palace issued a statement on behalf of 94-year-old Queen Elizabeth, the princes' grandmother. She said the family were saddened by how challenging the couple had found the last few years.

William said he had not talked to Harry since the interview was broadcast just over three days ago.

Prince Harry and Meghan, The Duchess of Sussex, have opened up about life in the British royal family in a tell-all interview with US television personality Oprah Winfrey. Meghan, who is biracial, said there were concerns about how "dark" her child would be.

The American also addressed the numerous rumours of intrigue between her and Kate Middleton, Duchess of Cambridge, married to Prince William, second in line of succession to the throne and Harry's older brother.

The turbulent life amidst the royal family -although the former actress spoke of maintaining good relations with Queen Elizabeth 2nd- even led Meghan to have suicidal thoughts.

Prince Harry and his wife Meghan, the Duchess of Sussex, are expecting their second child, a spokesperson for the pair confirmed.

"We can confirm that Archie is going to be a big brother," sp spokesperson. "The Duke and Duchess of Sussex are overjoyed to be expecting their second child."
