Prince Harry has been accused of racism again after reports that he told a comedian: "You don't sound like a black chap."
Mr Amos, who has appeared on many television shows including Have I Got News For You, said he put comment down to a poor attempt at making banter.
He said Prince Harry, 24, congratulated him on his performance before saying: "You don't sound like a black chap."
"I wanted to say: How is I supposed to sound?" said the comedian.
The new row comes after Harry was accused of racism after he referred to a Sandhurst colleague as "our little Paki friend".
He was also heavily criticised in 2005 after choosing to wear a Nazi uniform to a fancy dress party.
A former chairman of the Commission for Racial Equality says it shows how ill-educated members of the upper class can be.
Buckingham Palace is refusing to comment.
