One relates to an alleged incident last Wednesday in King’s Lynn, Norfolk, where the defendant is accused of threatening the former Duke of York. Mr Jenkinson is also accused of threatening another man, Stephen Terry, the day before. He denies both charges.

The King’s younger brother is due to give evidence via video link against Mr Jenkinson at the trial, scheduled for July 29 at Westminster Magistrates’ Court.

The prosecution asked for the ex-prince to be allowed to appear remotely, which was granted.

Mr Mountbatten-Windsor was walking his dogs when the incidendent is alleged to have taken place shortly after 7.30pm on Wednesday.

The defendant, who appeared in court via video link from King’s Lynn Police Investigation Centre in Norfolk with his right arm in a sling on Friday, did plead guilty to failing to provide a specimen of blood in custody.

He was granted conditional bail. The court ordered that he must not enter the county of Norfolk. He was also ordered not to contact Mr Mountbatten-Windsor directly or indirectly, not to approach or attempt to approach him, and not to go to or be within 500m of the following royal estates: Sandringham Estate, Buckingham Palace, Balmoral Castle, Windsor Castle and Highgrove.

The King’s brother moved to Marsh Farm in Norfolk last month, after extensive renovation work on the property was completed. He had been living at nearby Wood Farm after vacating his grand property on the Windsor estate at the start of the year.
