In a remarkable court scene, the prince took the stand for five hours to make his case that his phone was hacked by a newspaper group, as a lawyer for the defense grilled him about his claims.

Prince Harry took the stand in a case against the British tabloid newspaper “Daily Mirror” and more on June 6. He said journalists have “blood on their hands.”

Prince Harry arrived at a London court to testify against a tabloid publisher Tuesday, making him the first royal to enter a witness box in centuries.

As part of his mission to rein in the tabloid media, Harry is testifying and being cross-examined over at least two days in his suit against the Daily Mirror.

Prince Harry testified in London on Tuesday as part of the phone hacking lawsuit he brought against Mirror Group Newspapers, alleging that the tabloid press had hacked his phone and voicemails and those of his friends and associates to illegally obtain information about him.

Prince Harry appeared in court to testify in a lawsuit accusing Britain's Mirror Group Newspapers of illegal hacking as he said the tabloids coverage had a "devastating impact" on his mental health.

Harry made the accusations as he became the first high-ranking member of the British royal family to appear as a witness in court in 130 years.
