Queen Elizabeth resented Princess Margaret over contentious love life

Queen Elizabeth was hostile towards her sister, Princess Margaret, over her problematic love life that put the sanctity of the monarchy in danger.

Experts believe the differences between the two sisters came from Margaret's controversial string of affairs, and her choice of partners.

According to TheTalko, "She (Margaret) found herself at constant odds with the Queen because of her choice in partners."

Margaret’s lady-in-waiting, Anne Glenconner, penned a memoir titled Lady in Waiting: My Extraordinary Life in the Shadow of the Crown, wherein she wrote how Margaret's relationship with the Queen worsened, "Margaret was terribly loyal to the Queen — and being five years younger, I think it would have been much more difficult if she had been just (a little) younger than the Queen.

"There would have been more rivalry. She never said anything," Glennconner added.

For the unversed, Princess Margaret fell in love with Group Captain Peter Townsend - a divorced man. At the time, the royal family had forbidden its members to marry a divorced person.

She then got married to Anthony Jones-Armstrong. However, when trouble hit paradise, Margaret sought refuge in Roddy Llewellyn, a man 16 years younger than her.
