Meghan Markle did not understand her role in the Royal Family and didn't like not being able to share her opinions, a royal author has claimed.
The Duchess of Sussex did not like suppressing her views as royals are often required to do when representing the firm, it has been claimed by Tina Brown, the former editor of Vanity Fair.
The author argues that the 40-year-old did not put the ground work in as her late mother-in-law Diana did before trying to focus her efforts on humanitarian work.
Ms Brown examines the relationships within the Royal Family in her new book The Palace Papers.
“I think that was her fundamental sense of misunderstanding of what was going to happen when she joined the Royal Family — she saw the palaces and Diana as this global humanitarian superstar, but forgot that for 16 or 17 years Diana worked like a dog within the royal family doing a great deal of humdrum assignments," she recently told Lorraine Kelly in an interview.
“It was her charisma she brought to the job that made her so extraordinarily special.”
Ms Brown argues that the Princess “worked like a dog” for more than a decade before she became a global icon.
When asked by Lorraine how Meghan got on during her 2018 tour of Australia, the royal author said that she “didn’t like it at all”.
“She found the whole representational job of suppressing your own views and representing the monarchy just an anathema," Ms Brown continued.
“It’s not how she viewed her role, the world, she did not understand the point of it and for her, yes, she was a great success, but it was not something she wanted to do.”
The trip - which saw Meghan and Harry also travel to Tonga, Fiji and New Zealand - has become a source of contention within the firm.
During their tell-all interview with Oprah Winfrey last year, the Duchess said she did not feel protected during the trip.
At that point she was pregnant and she said the tour was a turning point in her relationship with the monarchy.
Ms Brown went on to lavish praise on Diana for focusing her own emotional discomforts within the royal family on humanitarian work.
She said: “Her husband wasn’t in love with her, that was the agony for her.
"She made the greatest thing she could: she took that suffering and turned it into her remarkable work, which was real and important.”
Last month Meghan received some plaudits for her work at the Invictus Games, which she attended alongside her organiser husband Harry.
The Duchess seemed at home chatting to contestants of the event - which sees injured service people compete in a variety of disciplines - and happily sitting in a miniature Range Rover alongside a child driver.
