Little Millie McMenamy had her big day when the new Crown Jewels exhibition was unveiled at the Tower of London.

She got to meet a real princess and was chosen to be the one to present her with a bouquet.

Millie is the youngest resident at The Tower, the daughter of Yeoman Warder Steve McMenamy.

She was selected to present the flowers when Princess Anne arrived to open the new-look exhibition to mark the Queen’s Diamond Jubilee.

The display in the Jewel House, which attracts two-and-a-half million tourists a year, now includes film of the Queen’s 1953 coronation and music by Handel. It also has a tactile three-dimensional model for the blind and visually impaired.

The Princess Royal accepted the bouquet from Millie after being greeted by the Constable of the Tower, General Lord Richard Dannatt, Historic Royal Palaces Chief Executive Michael Day and with a parade by Yeoman Warders more commonly known as Beefeaters—including Millie’s dad.

Palaces chief Mr Day said: “This display enables us to ‘showcase’ Britain’s most prized treasures in all their glory, with all eyes on London in 2012 for the Queen’s Diamond Jubilee and the Olympics.”

Princess Anne was also given a raven, a gift from a Somerset breeder to the Queen to commemorate the Diamond Jubilee, which joins seven other ravens at the Tower.

The Crown Jewels are still regularly used by the Queen in important national ceremonies, such as the annual State Opening of Parliament.
