Prince Harry and Prince William once used a secret code to communicate during their grandfather's funeral.
During an interview after the publication of his bombshell memoir Spare, Harry spoke about the code as he recalled how his brother "stopped him cold" when he used it at Prince Philip's funeral.
The two brother's relationship was already in ruins at that point after Harry and Meghan stepped down from their royal duties in 2020 and relocated to California to start a new life, the Mirror reports.
