In January 2008, it revealed details that UK Prince Harry was with the British army serving in Afghanistan, in breach of an agreement with the major news organisations. It ran updates on the story on two further occasions. When the United States Drudge Report ran the story on 28 February 2008, the prince was forced to abandon his posting and return to the UK. After the story broke much more widely, New Idea pulled the story from its web site and made itself unavailable for comment to other members of the press. Two months later, the magazine issued an apology for publishing the story. "We regret this serious lapse of judgment. We sincerely apologise to all our readers, to the servicemen whose lives are at constant risk while serving at home and abroad and to their families and loved ones."
