Andrew Mountbatten-Windsor is expected to appear as a witness next week in the trial of a man accused of threatening him near the Sandringham Estate.
The accused, Alex Jenkinson, faces two counts of using threatening, abusive or insulting words or behaviour with the intent to cause harassment, alarm or distress, according to reports.
One of the charges is understood to involve Mountbatten-Windsor, the younger brother of King Charles III.
Jenkinson has pleaded not guilty and is due to stand trial on July 29.
He has also denied a separate allegation involving another man, Stephen Terry, on May 5, one day before the reported incident concerning Mountbatten-Windsor.
The alleged encounter took place while Mountbatten-Windsor was walking his dogs near his residence on the Sandringham Estate with members of his private security team.
According to The Telegraph, which first reported the incident, he was left shaken by the encounter. People close to him reportedly raised concerns about his personal safety following the incident.
Jenkinson was charged and appeared at Westminster Magistrates’ Court on May 8 by video link, where he entered a not-guilty plea.
During the hearing, the court approved a request allowing Mountbatten-Windsor to give evidence remotely during the trial.
Mountbatten-Windsor, the father of Princess Beatrice and Princess Eugenie, currently lives on the Sandringham Estate after leaving Royal Lodge in Windsor.
