Prince William has been out with his step-sister Laura Parker ever since her parents got married, with the two taking part in ‘terrible’ fights time and time again.
Charles and Parker’s affair caused them to divorce their respective spouses which not only affected Prince William and Harry, but also the children of Laura Parker and Tom Parker and Laura Lopes.
Royal author Katie Nicholl wrote about the affair in her 2010 biography Harry and William, which dealt with the lives of the young princes behind closed doors.
“William and Laura used to have a terrible fight over who was to blame for their broken homes,” Nicholl wrote in her book.
She quoted a family friend as saying, “William would blame Camilla for all the hurt she had caused his mother, which would send Laura into a rage that Laura didn’t get. He would take a hard line and fire back to William: ‘Your father ruined my life!’ ”
Nicholl also wrote about how Laura and Tom were mercilessly bullied at school over their mother’s notorious relationship with Charles.
