Prince Harry's relentless pursuit of a phone-hacking case against The Sun newspaper may result in unprecedented consequences, potentially requiring a reigning monarch to testify in court.

The British publication argues that it's too late to initiate litigation for allegations dating back to the early 2000s. Harry, however, asserts that his father, King Charles, stepmother, Queen Camilla, and advisers from Clarence House had previously dissuaded him from taking legal action while he was a working royal.

Legal experts speculate that King Charles could be compelled to testify if the case proceeds to trial. In a surprising turn of events, Harry has also accused his brother, Prince William, of secretly settling with The Sun's parent company over similar allegations rather than pursuing a court case. According to The Telegraph, William's settlement exceeded $1.8 million.

Sources indicate that Harry's revelation was made without 40-year-old William's consent, potentially exacerbating the rift between the brothers as they prepare to reunite at the upcoming coronation.

This development comes as the royal family navigates numerous challenges, including the recent coronation of King Charles and Queen Camilla, as well as ongoing tensions between Prince Harry, his wife Meghan, Duchess of Sussex, and other family members.

With the spotlight on the royal family during this tumultuous time, it remains to be seen how these legal battles and strained relationships will impact their image and future engagements. As the world watches, the unfolding drama surrounding Prince Harry's legal case against The Sun continues to add complexity to an already delicate situation.
