Prince Harry had flown to the UK on June 4 to testify against the tabloid, Daily Mirror. He, along with other celebrities, accused Mirror of using unlawful means to access private information regarding their lives. He blamed the “prying eyes of the tabloids” for his break-up with former girlfriend Chelsy Davy. “As a child, every single one of these articles played an important and destructive role in my growing up”, he said during the trial. The duke blames press intrusion for his “acute paranoia of being constantly under surveillance”. He was questioned for a total of eight hours over the course of two days.

Although both his father, King Charles III, and his brother William, Prince of Wales were in London at the time, it is believe that Prince Harry did not meet either of them. Nor did he visit Princess Eugenie and her newborn son, Ernest.
