Britain's Prince William and his wife, Kate have marked their son's third birthday by releasing a photograph of him on his first day of nursery school.
Prince Louis is shown sat on his bike in the grounds of Kensington Palace, smiling for Kate – who took the picture on Wednesday.
Wearing a jumper, shirt, shorts and with his rucksack on his back, ahead of his first day at the nearby Willcocks Nursery School.
Louis celebrates his third birthday on Friday and is following in the footsteps of his sister Charlotte, aged five, who also attended the same nursery.
Kate is a keen and accomplished amateur photographer, who in 2017 accepted a lifetime honorary membership of the Royal Photographic Society which recognised her “talent and enthusiasm”.
She regularly releases images of her children to mark important occasions like birthdays and other major milestones.
The school has been described in reports as having a loyal following of “old English families and chic foreigners”.
The school charges fees of £3,400 (€4,000) per term for children attending what it calls morning school and £2,250 (€2,600) per term for those enrolled for the afternoon.
The two-week period of royal mourning following the death of Prince Philip ends on Friday, allowing Louis' family to release the birthday image.
Louis is fifth in line to the British throne, born on April 23rd, 2018, at the private Lindo Wing of St Mary’s Hospital in Paddington, London.
He was christened Louis Arthur Charles at 11 weeks old, by the Archbishop of Canterbury Justin Welby at the Chapel Royal, St James’s Palace.
