Princess Eugenie has followed in the footsteps of her great-great-grandfather by getting a tattoo.

       The Queen’s granddaughter, 32, has had a small circle inked behind her left ear.

       It was spotted as she left the Platinum Jubilee service of thanksgiving at St Paul’s Cathedral, which she attended with Jack Brooksbank, her husband.

       On Thursday, the couple shared footage on Instagram of their one-year-old son August’s first Trooping the Colour, watching the Red Arrows fly-past from the roof of St James’s Palace:

       Princess Eugenie – who is now splitting her time between London and Lisbon, Portugal, where her husband has just got a new job – wore a bright orange dress by designer Emilia Wickstead, a long-time favourite of the Duchess of Cambridge.

       Although members of the Royal family have to follow strict dress codes, there is a surprisingly long tradition of body art in the monarchy – although it is unlikely that the Queen would approve of too much inking.

       In 1862, Albert, the Prince of Wales – later King Edward VII – was one of the first to dabble in tattoos, when he had a Jerusalem Cross tattooed on his arm during a visit to the Holy Land.

       Twenty years later, his son George – later King George V, the Queen’s grandfather – was tattooed during a trip to Japan. He was just 16 when he got a dragon and a tiger on each of his arms.

       He and his brother, the Duke of Clarence and Avondale, served as midshipmen aboard HMS Bacchante and got the designs to serve as a permanent reminder of their trip to the Far East.

       Princess Eugenie is not the first modern-day member of the Royal family to get a tattoo either. Lady Amelia Windsor, the granddaughter of the Duke of Kent, the Queen’s cousin, has a heart-shaped design on her rib cage and a tiger drawn on her shoulder blade.
