It’s been one month since Prince Harry and Meghan Markle sat down with Oprah Winfrey for an explosive tell-all interview about the British royal family. Now, a royal biographer is speaking out to say that Queen Elizabeth sees her grandson Harry as “a bit of a lost soul” like her late sister, Princess Margaret.

“I think the Queen knows that being the spare is hard and a part of her recognizes that Harry was a sometimes a bit of a lost soul just like her sister,” Andrew Morton told Vanity Fair. “She has always wanted to protect Harry and I think in part that’s because she watched Margaret fall victim to the system. Shutting out Margaret didn’t help and the Queen has learned from that. She didn’t want history to repeat itself with Harry.”

Morton is the author of the new book “Elizabeth & Margaret: The Intimate World of the Windsor Sisters,” which examines the sisters’ close yet often tense relationship.

Margaret, who passed away in 2002, always struggled to find her place in the monarchy. Since Harry stepped down from the royal family, the parallels between him and Margaret are obvious.

“When you compare personalities, Harry is like Margaret, a royal rebel. Margaret once said ‘disobedience is my joy’ and you see some of that in Harry,” Morton explained. “The Queen also knew Margaret sometimes felt like an outsider and I think that’s why she has made sure the door is always open for Harry to return to the royal fold. She will have a lot of empathy and sympathy for him because she grew up watching her younger sister act the role of the spare, which is not easy.”

Though Harry is difficult for her to understand sometimes, the Queen loves him dearly, just like she loved her late sister.

“She has a lot of affection for Harry. She was there the day Harry lost his mother and has been there for him ever since,” Morton added. “She has deliberately taken him under her wing. I think as a grandmother she has been far more understanding than as a mother at times.”
