He is taking the stand — and spreading more royal gossip and allegations — in multiple lawsuits against the British press.

LONDON — Prince Harry is about to take his battle with the media to a historic new stage, becoming the first high-ranking member of the British royal family in 130 years to appear as a witness in court.

The last senior British royal who spoke in court was Princess Anne, Harry’s aunt, in 2002. Her one-word statement: “Guilty.” Anne was charged under the Dangerous Dogs Act after her English bull terrier Dotty attacked two children in Windsor Great Park. The princess was ordered to better train her dog and pay about $1,400.

Prince Harry will become the first British royal to appear in the witness box since the 1890s when he testifies this week at the High Court in London as part of his lawsuit against Mirror Group Newspapers.

Prince Harry will take to the witness stand Tuesday as his years-long battle against Britain’s tabloid media reaches its most dramatic stage so far.

Unlawful information-gathering "acted like a web" around Prince Harry, a court has heard during his trial against Mirror Group Newspapers (MGN). His barrister told London's High Court no aspect of his youth was safe from press intrusion - citing stories about his relationship with Chelsy Davy appearing in the Mirror.

Though the royal “surprised” the judge with his absence from the London courtroom, his lawyer previewed some of the issues he will talk about when he takes the stand on Tuesday.
