Dark Secrets Behind Prince Charles’ Romantic Relationship With Princess Diana’s Sister

It’s fairly common knowledge that Prince Charles was associated with a number of women before he dated and married Lady Diana Spencer. But what many don’t know is that he dated Diana’s sister, Lady Sarah McCorquodale, prior to that. But it doesn’t stop there — their relationship and subsequent falling out wasn’t without scandal.

For starters, when did this happen?

Prince Charles and Lady Sarah dated in 1977. She even credits herself with introducing Charles to her younger sister — and his future wife — after her own relationship with him had fizzles out. “I introduced them. I’m Cupid,” she reportedly said after the two got engaged.

While they certainly steal many headlines, members of the British royal family don’t really talk to the press. They either give a well-rehearsed interview, or send out a general memo from the palace. So naturally, it didn’t go over well when the then Lady Sarah Spencer sat down to lunch with two reporters and dished about being Prince Charles’ girlfriend.

Despite seeming infatuated with her connection to the royal family, Lady Sarah reportedly let if fly that she had no intention of marrying the Prince of Wales. In fact, she went so far as to say that she wouldn’t marry Charles “if he were the dustman or the King of England.”

Not long after her lunch with Whittman and Nelson, Sarah’s quotes surfaced for the public to read. Needless to say, Prince Charles was less than amused. According to Wikipedia, Charles said: “You’ve just done something incredibly stupid.” He broke off the relationship after that, and were not on good terms for some time.

A few outlets have hinted that their relationships with Charles put strain on Sarah and Diana’s relationship. However those close to the two, including their brother Andrew Morton, claim that the sisters remained close even though Diana married Charles. At the end of Diana’s life, Sarah even served as one of the ladies-in-waiting.

Following Diana’s tragic death, Lady Sarah McCorquodale worked to keep her late sister’s memory alive.

Sarah has also reportedly stayed close to Diana’s sons, Princes William and Harry. (She was also at Prince William’s wedding to Kate Middleton in 2011.)
