Princess Margaret recognized the power and command of her older sister, Queen Elizabeth II, in a resurfaced interview.

In her interview with author Andrew Duncan, the late princess praised the Queen. She also shared how she helped the monarch with her responsibilities.

"My sister has an aura. I’m enormously impressed when she walks into a room. It's a kind of magic," Princess Margaret said (via Express). "In my own humble way, I've always tried to take some of the burden off my sister. "

"She can't do it all – and I leap at the opportunity to help," she continued. "Sometimes it can be very formal and boring, but I've got a reflex against that now. It's very much up to one not to be bored."

In Channel 5's documentary, "Elizabeth: Our Queen," Princess Josephine Loewenstein recalled her conversation with Princess Margaret when the latter saw the Queen cry.

"I've only seen my sister cry once," Princess Loewenstein shared what Princess Margaret told her. "It was when the Press put all the articles about her not getting on with Margaret Thatcher."

According to the reports, Her Majesty said "can't that woman just sit down," when Thatcher was staying in Balmoral. The rift between the two was chronicled in the book "The Queen and Mrs. Thatcher: An inconvenient relationship" by Dean Palmer. Queen Elizabeth II reportedly mocked the former PM's accent, made jokes behind her back and called her "that woman."

In the same documentary, Queen Elizabeth II reportedly thanked a friend for introducing Princess Margaret to Roddy Llewellyn, who was 17 years her junior. The two had an affair.

"It was difficult for the Queen and I felt rather guilty always having introduced Roddy to Princess Margaret," Lady Anne Glenconner said. "But after Princess Margaret's funeral, the Queen, she said, 'I'd just like to say, Anne, it was rather difficult at moments, but I thank you so much introducing Princess Margaret to Roddy 'cause he made her really happy.'"

Princess Margaret had a mild stroke in 1998. She suffered from another stroke in 2002 which caused her death. Her funeral was held on Feb. 15, 2002.
