Princess Eugenie reveals why this breach of royal protocol got her 'in trouble'

Princess Eugenie has revealed that her recent breach of royal protocol left her in trouble with senior members of the family and royal aides.

The 29-year-old York daughter recently posted a picture of her father, Prince Andrew, in the corridors of Buckingham Palace following the Trooping the Colour ceremony, to her private Instagram.

And now, in a new interview with British Vogue, she confessed that the photo landed her in hot water at the palace.

She admitted, "I recently got in trouble for posting a picture of Papa in a corridor of the palace that was off-limits to the public,"

Presumably, the corridor is a private part of the royal abode - and may likely even form part of the Queen's private residence within the palace, suggesting why she got in trouble, unknowingly, for sharing it.

The background however didn't look much like your normal family home - full of golden-edged furniture and paintings, and a rich red carpet running down the hallway.

It's no surprise that Eugenie has been the first of the royal family to experience this kind of social media faux-pas.

She is the first senior member of 'The Firm' to have her very own personal Instagram account - the likes of Meghan Markle and the Duchess of Cambridge can only communicate with their fans through official channels, including the Kensington Palace Twitter account.

Shortly after Meghan's engagement to Prince Harry was announced, she was made to shut down her personal social media accounts, which she previously used on a regular basis.

Princess Eugenie created her social media account in March, shortly after she became engaged to her boyfriend Jack Brooksbank.

Since then, she has shared numerous, adorable family photos, and pictures of her working life. And the account has provided royal family followers with a rare, candid insight into the lives of one of the most private families in the world.

As Eugenie is not a working royal (i.e, she doesn't complete duties on behalf of the Queen in an official capacity), she was allowed to create her own public profile - unlike her cousins Harry and William, and their respective wives.
