Prince Harry's historic court testimony against tabloid publisher.

Prince Harry is set to appear in London's High Court to give evidence and face questions about his allegations of phone hacking against the tabloid press. He will face tough questioning about personal news stories, including his relationships, his mother Diana, and his life growing up in the Royal Family. The stakes are high as the argument is made that senior executives must have known what was going on. This is a court confrontation that could be traced back to the death of his mother Diana, and it is his day of reckoning.
