British newspapers have shied away from publishing nude photos of Prince Harry cavorting with friends in Las Vegas, after a warning was issued to editors by the royal family.
In one of the two photos, the naked 27-year-old is pictured covering his genitals with his hands while another person, apparently a nude woman, stands close behind him.
In the other, he is bent over bear-hugging a second person, who also appears to be naked. It is not clear if the person is a man or a woman.
Clarence House, which represents Harry's father, Prince Charles, confirmed on Wednesday the images were genuine.
"At this time we don't have a comment," a spokesman said. A royal spokesman later confirmed the family had contacted the Press Complaints Commission to ask British newspapers not to print the images, arguing it would be a breach of privacy.
