New photos of Prince Louis to mark his first birthday on Tuesday have been released.

Taken by his mother, the Duchess of Cambridge, the pictures show the fifth in line to the throne playing in the garden of the family home in Norfolk.

Two of the photos show a smiling prince wearing a red jumper, while in the third a more serious Louis is sporting a blue number.

Born at 11.01am on 23 April 2018 – St George’s Day – weighing 8lb 7oz, Prince Louis is the youngest of the Duke and Duchess of Cambridge’s three children and the great-grandchild of the Queen and Duke of Edinburgh.

Just last month during a visit to a children’s centre his mother described him as an active child who enjoyed bombing around on a walker.

He just wants to pull himself up all the time. He’s got these little walkers and is bombing around on them, she said.
