When Meghan Markle and Prince Harry attended the Queen’s Young Leaders Awards, horror ensued.

No, she didn’t blow her nose too loud, walk ahead of the Queen or make an outfit faux pas, and we can report that her hair was perfectly coiffed. Instead the 36-year-old was caught… crossing her legs while sitting.

*gasp*

We know. Someone alert the Princess Crimes Committee ASAP.

Sadly, social media commentators immediately picked up on Meghan's 'improper' sitting, with tweets coming in fast that Meghan failed to adopt the ' Duchess slant,' which is (apparently) the only way royal women are allowed to sit.

"She's not yet mastered the 'Duchess slant' I see!" wrote Twitter user, ScreamNevermore.

"I don't think that's a duchess slant, it looks like she’s crossed her legs," commented another.

However, thankfully others noticed the ridiculousness of the situation. One tweet even noted that the pose is in fact called the Duchessslantand not the Duchessun-cross, meaning that technically Meghan's pose still ticks royal protocol.

Those who say Meghan should not sit like that are just plain ignorant. It’s called the duchess slant not the duchess un-cross ???? I suspect those who cry foul against the protocols don’t even understand the protocols. pic.twitter.com/dIaI8sF1yg

Another Twitter user was also quick to note that even the late Princess Diana was guilty of crossing her legs at official events too, which we appreciated very much.

If someone mentions anything about how the way Meghan sat today broke any protocol, remind them that the "duchess slant" has different styles, but the main point is that your legs are locked together and slanted. If they still talk about protocol, then their ignorance is glaring. pic.twitter.com/lsTnjza0Ub

While the 'Duchess slant' is adopted by most female royals, the term came into popularity when people realised that it was the seating position nearly always adopted by the Duchess of Cambridge. This isn't the first time the Duchess of Sussex has been criticised for sitting incorrectly either, in November of last year, that Meghan's habit for crossing her legs was the one thing the royals weren't happy with.

Sitting issues aside (snore), this isn't the only headache currently troubling Royal HQ at the moment, with Meghan's father Thomas Markle openly criticising the Queen in his latest interview.

Speaking to TMZ, the 73-year-old said that he was annoyed that he's yet to meet the royal family and believes that he's been put in the "penalty box" since hisGood Morning Britaininterview last week.

“If the Queen is willing to meet our arrogant and insensitive President she has no excuse not to meet me, I’m nowhere near as bad,” he said.

Despite this, a father-daughter reunion could be in the works soon, withTMZreporting that he does eventually want to travel to London and finally meet his son-in-law in person.
