Britain's Prince William and his wife Kate have released three new photographs of their youngest son, Prince Louis, to mark his first birthday on Tuesday.
Two of the photographs show Louis in a woodland setting with moss stuck to his red sweater, while in a third he sports a blue jumper with a picture of a dog on the front.
All were taken this month by Kate at the family's home in Norfolk, eastern England, Kensington Palace said.
Louis Arthur Charles, who is fifth in line to the throne, was born on April 23 at 11.01am, weighing 3.8 kilograms. The three names honour both the Prince's grandfather, Prince Charles, and Louis Mountbatten, the Duke of Edinburgh's mentor who was killed by an IRA bomb in 1979.
The young royal also has a five-year-old brother, Prince George, and a three-year-old sister, Princess Charlotte.
Louis is a great-grandson of Queen Elizabeth II, who turned 93 on Sunday.
He has largely been kept out of the public eye since he was born.
