The former butler to Diana, Princess of Wales has blasted Prince Harry's deployment to Iraq, branding it a publicity stunt by the British monarchy. Paul Burrell is furious at the cost of keeping the royal heir protected while he fights in the Middle Eastern war zone. He says, "Harry is a wild card... a liability. It's going to cost the taxpayers a lot to keep him safe in Iraq. "It's just a PR exercise - because when he comes home he'll be a hero."
