Pippa Middleton broke huge Wimbledon rule and was refused entry in Royal Box with Kate

We're just a matter of days away until celebrities, politicians, and, of course, the royals rally together to attend Wimbledon, which kicks off next week (29 June)

Amidst all the tennis playing, strawberries and copious amounts of Pimms, fans will no doubt be keen to see who sits where in the Royal Box - AKA the area which has been used 'for the entertainment of friends and guests of Wimbledon since way back when in 1922.

British and overseas royal families are often invited to the VIP-only area, as well as heads of government, people from the world of tennis, commercial partners, prominent media organisations, famous faces, supporters of British tennis, and many more.

With that said, however, such invitees have to follow a very strict set of rules when it comes to the Royal Box or else they'll risk getting turned away altogether.

And Kate Middleton's sister, Pippa, knows that firsthand after being denied entry back in 2017 due to a late arrival.

According to the Daily Express, Pippa and her mother Carole were denied the chance to sit with the rest of their family because they turned up late to see Andy Murray take on French professional Benoit Paire.

Instead of getting to sit with their fellow famous faces, they were taken to the regular seats, situated behind the box.

However, it didn’t seem to get them down, as in all of the photos from the day out, they seemed to be having a whale of a time.

Meghan Markle also reportedly got turned away in 2019 due to another dress code-related issue - and it’s not what you’d expect.

The Duchess of Sussex turned up to watch the tennis competition in a pair of blue jeans, something that is not permitted, according to The Times.

The protocol is to dress smartly - this means suits and jackets with a tie for men.

Ladies are also asked not to wear hats, as they tend to obscure the vision of those seated behind them.

Lewis Hamilton knows about the seriousness of the dress code all too well, after he famously missed the legendary final match between Novak Djokovic and Roger Federer because he in 2015 didn’t stick to the dress code.

The Wimbledon website explains that gentlemen in the Royal Box must wear a tie - something that he seemed to forget.

It also didn’t help that the Formula 1 star also arrived fashionably late!
