A British politician who is the sole remaining co-claimant in Prince Harry's lawsuit against Rupert Murdoch's News Group Newspapers (NGN) alleging unlawful information gathering by the tabloid publisher arrives at a London court for the start of the trial after years of legal wrangling. Tom Watson is a former deputy leader of the ruling Labour party who now sits in the House of Lords. The pair accuse The Sun and now-shuttered News of the World of using unlawful newsgathering techniques to generate stories about them more than a decade ago, and that NGN executives deliberately covered up their practices by deleting emails.
