Britain's Princess Charlotte is seen in this undated handout photograph, taken at Anmer Hall in Norfolk, and released by Prince William and Catherine.

A beaming Princess Charlotte headed off to her first day at nursery - and her big moment was captured on camera by her proud mom Kate.

Princess Charlotte's first day at nursery school has been marked by the release of two pictures taken by her proud mother, the Duchess of Cambridge.

The two-year-old, who is fourth in line to the throne, was photographed at Kensington Palace before travelling to nearby Willcocks Nursery School.

Charlotte is pictured sitting down on some outside steps in the grounds of the famous palace, while another photograph shows the little girl standing as she holds onto a rail.

The young princess is wearing a red coat, £120, by Amaia Kids teamed with a pink scarf, and a Cath Kidston pony rucksack, demonstrating perhaps that she already shares her great-grandmother the Queen's love of horses. 

Kate, who celebrates her 36th birthday on Tuesday, is a keen and accomplished amateur photographer who last year accepted a lifetime honorary membership of the Royal Photographic Society which recognised her "talent and enthusiasm".

The Duchess bucked tradition when she took the first official photographs of her newborn daughter in 2015.

The photos of Charlotte showed the young princess being cradled by her older brother Prince George at William and Kate's Norfolk home, Anmer Hall.

The history of art graduate, has also released pictures to mark other milestones in her children's lives, including George's first day at nursery school and Charlotte's first birthday.
