The Duke of Sussex will travel to the UK to visit King Charles “in the coming days” after Buckingham Palace announced that the monarch has cancer, the BBC has learned.
A spokesman for Prince Harry said he had spoken to his father about the diagnosis.
The Duke moved to the United States with his wife, Meghan, Duchess of Sussex, after they stepped down as senior members of the royal family in 2020.
Since then, his relationship with some other members of the royal family has been strained.
The spokesman said that Meghan would remain in the United States with her two children.
The Duke's last appearance at a royal event was in May, during the King's coronation.
It was quick, as Prince Harry left immediately after the ceremony at Westminster Abbey.
The BBC has learned that he was not invited to appear on the balcony of Buckingham Palace after the ceremony.
A source also told US media Page Six at the time that Prince Harry intended to make “every effort” to return in time for his son Archie's birthday – which was on the same day.
Diagnosis of King Charles Cancer
Recently, the Duke traveled to the United Kingdom to attend libel cases involving British newspapers.
Prince Harry and Meghan spoke about life in the royal family and their disagreements with members in his memoir Spare, an interview with Oprah Winfrey and a Netflix documentary.
The prince told Winfrey that King Charles stopped returning his calls when he was trying to discuss stepping down as a senior royal.
Prince Harry also noted that the King had pleaded with his children, saying: “Please, children. Don't make my final years miserable” after the funeral of the King's father, Prince Philip.
The palace said that the King called Prince Harry to inform him of his health condition.
As told to the Prince of Wales, heir to the throne, as well as the King's siblings: the Princess Royal, Princess Anne; Duke of York, Prince Andrew; The Duke of Edinburgh, Prince Edward.
