This is the photo that earned Princess Eugenie a royal telling-off

Princess Eugenie has revealed the candid photo of her father that landed her in hot water.

The youngest daughter of the Duke and Duchess of York shared a picture of Andrew inside Buckingham Palace in June after the Trooping the Colour ceremony.

But the seemingly innocent snap revealed to her 288,000 Instagram followers a part of the palace normally closed off to the public — and subsequently earned her a telling-off, the Daily Mail reports.

Speaking to British Vogue, Eugenie explained: "I recently got in trouble for posting a picture of Papa in a corridor of the palace that was off-limits to the public."

Eugenie, 28, was explaining her dilemma over choosing a photo to mark Father's Day — fearing a Balmoral snap would be "too personal" and an Ascot photo "too formal".

In the offending photo, Andrew, 58, looked smart in his regimental uniform following his debut as Colonel of the Grenadier Guards.

The corridor, lined with marble busts and a plush red carpet, was hung with paintings including one depicting the wedding of Princess Maud of Wales, a granddaughter of Queen Victoria.
