Queen Elizabeth II was perplexed and had concerns when Prince Harry did something shocking.

Katie Nicholl, a royal specialist, claims that the previous ruler found it difficult to accept Prince Harry and his wife, Meghan Markle, leaving their positions as senior working members of the British royal family.

In 2020, the Duke and Duchess of Sussex sensationally announced their resignation from their royal obligations. Prince William's younger brother has frequently denied reports that his and his wife's decision "blindsided" his grandmother.

Katie made the claim in the book "The New Royals" that Queen Elizabeth II never truly understood her grandson's desire to avoid the responsibilities of living as a royal, especially in light of her vow to devote her life to public service and the stability she provided as the head of the British royal family up until her passing.

The Queen, she said, didn't get why Prince Harry had to give it up, according to The Mail's Palace Confidential.

The 96-year-old ex-royal, who was never intended to be Queen, vowed to uphold the monarchy during her whole life. Duty was ingrained in her, the expert said.

Prior to the start of her reign, Queen Elizabeth II made a radio speech on her 21st birthday in which she pledged to spend the rest of her life serving the needs of the royal family.

After the Duke of Sussex remarked that nobody wanted to be king, she claimed that "[the Queen] just couldn't comprehend that comment."

She was forced into doing something that "no one would desire duty" because she had no other option.

A young Queen named Elizabeth II was thrust into the foreground of the royal realm following the abdication of King Edward VIII, who left his position as king to wed an American divorcee. Elizabeth II was now second in line to the throne behind her father.

In a 2017 interview with Newsweek, Prince Harry was asked if there was anyone who wanted to be king or Queen, and he answered, "I don't think so, but we will carry out our duties at the right time."

The British royal family, he argued, should continue to exist for the "better benefit of the people" as opposed to any one member's wish to become Head of State.

The hardships Prince Harry faced and the obligations he felt as a member of the royal family were also discussed, and he reflected on these in his shocking 2021 interview with Oprah.

He asserted that his brother Prince William and his father, now-King Charles III, are "trapped" because they don't get to go, and he felt they are "trapped within the system."
