On Tuesday, prince harry is set to make history by being the first senior British royal to testify in court in over a century in the case against a tabloid newspaper publisher.
Harry, 38, is due to testify before London's High Court in a case involving illegal information-gathering charges against Mirror Group Newspapers (MGN).
The Duke of Sussex and other high-profile persons claim that the publisher engaged in criminal acts, including phone hacking, at its titles and are seeking restitution.
Since stepping down from royal duties in early 2020 and relocating to the United States, Harry has initiated various cases against British newspaper groups.

The MGN experiment, planned to last up to seven weeks, began last month, only days after Charles' crowning on May 6, which Harry attended.
In March, the California-based prince unexpectedly appeared in the High Court for a privacy action he and others had filed against Associated Newspapers (ANL), publisher of the Daily Mail.
The Duke of Sussex made written contributions in that case but did not provide in-person testimony, sitting in the back of the court for several days.
His testimony, scheduled for Tuesday, is anticipated to be the first by a senior royal since Edward VII, who testified in an 1890 slander trial before becoming monarch.
This came when The Duke of Sussex lost a legal appeal demanding the right to pay for his police protection in the United Kingdom. The duke was contesting the decision to remove his police protection after he retired as a working royal.
The judge, Mr Justice Chamberlain, refused the duke's legal appeal to revisit the decision not to enable him to pay for police protection with his own money.
Omid Scobie, Harry's unofficial biographer who co-wrote a best-selling 2020 book on Harry and Meghan, said in a submission that he was instructed how to hack voicemails while working at MGN titled The Sunday People.
Omid Scobie also claimed that while on work experience at The Mirror's sister publication, he overheard then-editor Piers Morgan being told that information for a piece about Australian music diva Kylie Minogue came from voicemail. Morgan has denied any involvement in the scandal.
