The royals apparently broke protocol the other day by doing this

Remember when Meghan Markle and Kate Middleton made their first public appearance together this year for Prince Charles' party on Tuesday? Well it turns out they might've broken royal etiquette, and so did the Queen, Prince William and Prince Harry.

They all gathered at Buckingham Palace to celebrate 50 years since Prince Charles being the Prince of Wales, and they were all filmed making a great entrance as a group.

Therein lies the problem according to a royal expert on Twitter, as according to protocol, the family are meant to enter in order of rank, so it should've been the Queen first, then Prince Charles, followed by William and Kate, then Harry and Meghan.

The same goes with how the family exits a room, with the more senior royals leaving first.

However, experts have also pointed out that the Order of Precedence is usually to be followed at more diplomatic events, and as this occasion was more intimate, protocol didn't need to be followed quite so strictly.

Penny grew up in France and studied languages and law at the Sorbonne Nouvelle University in Paris before moving to the UK for her MA in multimedia journalism at Bournemouth University. She moved to the UK permanently and has never looked back (though she does go back regularly to stock up on cheese and wine).

Although she's always loved fashion - she used to create scrapbooks of her favourite trends and looks, including Sienna Miller and Kate Moss' boho phase - her first job was at MoneySavingExpert.com, sourcing the best deals for everything from restaurants to designer sales.

However she quit after two years to follow her true passion, fashion journalism, and after many years of internships and freelance stints at magazines including Red, Cosmopolitan, Stylist and Good Housekeeping, landed her dream job as the Digital Fashion Editor at Marie Claire UK.

Her favourite part of the job is discovering new brands and meeting designers, and travelling the world to attend events and fashion shows. Seeing her first Chanel runway IRL at Paris Fashion Week was a true pinch-me moment.
