There are dozens of known rules Meghan Markle is expected to follow as a member of Britain’s royal family, but there’s also a couple the public may not be aware of. 

Last September, The Daily Star revealed that the Duchess of Sussex is expected to adhere to a few specific guidelines when attending a dinner party. According to the outlet, one of the “bizarre” rules includes never revealing to fellow guests why she is leaving the table.

“When it comes to dinner parties, table etiquette is important and the Duchess of Sussex must think twice about what she says,” the publication reported, adding, “A member of the Royal Family must never ‘announce their intentions’ when they leave the table.

Should the Duchess or any other royal need to depart the gathering, they would simply need to say “excuse me” and leave. And the royal protocol doesn’t stop there.

Should a royal leave in the middle of a meal, they are expected to cross their knife and fork to symbolize they’re not finished eating. This move would allow staff to know a plate is not ready to be cleared. The outlet explained, “And if they’ve licked their plate clean before nipping to the loo, they must put their cutlery at an angle, with the handles at the bottom right of the plate.”

While Meghan is expected to follow these purported rules since marrying Prince Harry in 2018, she has been known to break royal protocol on several occasions. 

During her pregnancy with son Archie Harrison, Meghan decided against delivering at the famed Lindo Wing of St. Mary’s Hospital in London in favor of a private delivery. She also attended a baby shower for herself in the U.S., which is unusual for a British royal.

In July, an insider told Us Magazine that Meghan, 38, is determined to live by her own rules. 

“This is her life but her mentality is like, ‘Well, if this is what it’s going to be like, I’m going to do what I want to do. I won’t play by these rules,’” a source explained at the time, adding, “[Meghan is] figuring out what she can do in terms of being active [and more] comfortable with her role.”
