Prince William Always Breaks Royal Protocol For His Kids

Because he's a dad first.

There's nothing a parent wouldn't do for their kids, and for Prince William that includes breaking royal protocol.

According to Marie Claire, the Duke of Cambridge stopped following one rule of royalty after becoming a father. The rule in question forbids two heirs to the throne from travelling on the same plane together.

The royal protocol was put in place as a safety measure to avoid losing more than one heir if a crash occurs. However, if you recall, Prince William is known for travelling in the same aircraft as his wife, Kate Middleton, and their two kids: Prince George, 4, and Princess Charlotte, 2.

In fact, just last month the royals broke protocol by travelling together to Poland and Germany for their second tour as a family-of-four. Naturally, there were plenty of picture-perfect photos of them getting on and off their planes.

This is a big no-no considering William, George, and Charlotte are all heirs to the throne after William's own father, Prince Charles.

BBC reports that the 35-year-old dad first broke royal protocol a year after his son was born. At the time, the prince asked Queen Elizabeth II for special permission to fly with his baby boy while on a royal tour of Australia and New Zealand in 2014.

"While there is no official rule on this, and royal heirs have travelled together in the past, it is something that the Queen has the final say on," a royal spokesperson told the site.

More from HuffPost Canada:

The royals aren't strangers to breaking royal protocol every now and then. Back in June, Prince William hugged a victim of London's Grenfell Tower fire, despite etiquette stating that "members of the public are only allowed to shake hands with the royals," Entertainment Weekly reports.

Prince Charles also once gave his autograph to a family whose home had been destroyed in a flood, despite the rule that royals are only permitted to sign official documents.

And back in 1952, Queen Elizabeth herself broke protocol when someone forgot to pack her a black dress while travelling, which is required in case someone dies. Unfortunately, the broken rule could not have come at a worse time, as it was her father, King George VI, who passed away at the time.
