Princess Diana would not have been a "great fan" of Meghan Markle, according to one of the late royal's friends.
UK magazine editor Tina Brown made the claim in a recent interview with US website The Daily Beast.
"Diana would have been very, very protective of Harry and I believe very anxious about this direction they [he and Meghan] have taken," she said.
The Diana Chronicles author also claimed the princess would have been unhappy with Harry's decisions after he stepped back from the royal family and relocated to the US.
"I think she would have felt Meghan was steering Harry in a direction that was not good. I don't think Diana would have been the great fan of Meghan that Meghan herself might perhaps imagine."
Brown also claimed Diana was not "anti-monarchy".
"She never questioned whether Prince William would be king. It was her most ardent desire he would become king. She was never anti-monarchy in that regard," Brown told the Daily Beast.
"She had differences with the royal family - her biggest difference was that her husband wasn't in love with her, he was in love with someone else.
"But she never thought for one minute that William would not be the future king, and that Harry would always be there to support him. She would not be happy with how things are."
She also believed had Diana still been alive today, she would have been one of the most influential figures in the world.
"Unlike Harry and Meghan she understood having the power base of monarchy was enormously important. Today, I believe she would have had billions of followers on Instagram, and used that to the max.”
“By now, her charitable foundation would have been as big as Bill Gates’. She began that global humanitarian celebrity outreach that we went on to see with the Clooneys and Bono.
"She’s a real forerunner of that. It’s very tragic to know that didn’t happen.”
