After putting his foot in his mouth with comments about a Pakistani army officer, Prince Harry is under fire again for another racially insensitive remark, having apparently told a comic, “You don’t sound like a black chap,” reports.

Harry, allegedly attempting to be funny, delivered the line in November, when black comedian Stephen K. Amos performed at Prince Charles’ 60th birthday party. Amos spoke about the incident this week on a U.K. chat show. At the time, recalled Amos, “I wanted to say, ‘How is I supposed to sound?’”

Reaction to the exchange has been strong. “Many young people will be disgusted by his remark,” said Naomi Byron, national secretary of Youth Against Racism in Europe to the U.K.’s Daily Mirror.

“But it is not just Prince Harry that is at fault. The aristocratic, rich circles he moves in obviously don’t have a problem with this kind of racist stereotyping.”
