MEGA Prince William and Prince Harry's feud started years before Spare was published. "I think the moment that we realized that there were tensions between the brothers was after I printed a story in Vanity Fair about William just urging Harry to take his time because they were engaged," royal expert Katie Nicholl told The Sun. "Of course, William had taken many years before he proposed to [Princess Catherine] because he wanted her to be his wife. He wanted her to be able to know that this was what she wanted for her life, too," Nicholl said, referring to the Waleses' decade-long courtship.
