Prince Charles and Camilla Parker Bowles reportedly had someone from the royal family who was on their side.

In Netflix's documentary "The Royal House of Windsor," it was learned that the Queen Mother was fine with the Prince of Wales affair with Camilla even if he was married to Princess Diana. However, she wanted their romance to be private, so it won't cause a scandal.

"The Queen Mother is relatively broad-minded," Piers Brendon explained (as quoted by Express). "She didn't mind Prince Charles having an affair with Camilla Parker Bowles, provided that this did not become a scandal."

Queen Mother knew that the affair would be scandalous once it would be publicized. She knew how it affected the monarchy when King Edward VIII abdicated the throne to be with Wallis Simpson, a divorced American socialite who was pursuing another divorce to her second husband.

She didn't want Prince Charles and Camilla's affair to develop into the same magnitude as King Edward VIII's. Queen Mother showed her support to Prince Charles and Camilla by allowing the couple to use her Scottish home, Birkhall, as their bolthole.

Queen Mother and Prince Charles were very close. In fact, there was a point when she had a feud with Prince Philip because the latter wanted to send the Prince of Wales to Gordonstoun, his old school in Scotland to toughen up the future king. The school is known for developing one's character and intellect to produce a tough boy. On the other hand, Queen Mother wanted Prince Charles to attend Eton.

"He hated it, whenever he could, he escaped from school to stay with his grandmother," the narrator said about what Prince Charles did during those years in Gordonstoun.

When Queen Mother died, Prince Charle was devastated. In fact, he couldn't help but recall their fun times together.

"And I had dreaded, dreaded this moment. Above all, she saw the funny side in everything and we laughed until we cried. And oh, how I shall miss those laughs," Prince Charles said.

On the other hand, Queen Elizabeth II and Prince Philip disapproved Camilla and Prince Charles' affair. In fact, the Duke of Edinburgh called his own son "silly" for leaving Princess Diana for Camilla. There was also a time when the monarch didn't want to see the Duchess of Cornwall in any royal function.
