The Duke of Cambridge has made his first public appearance since leaving hospital with his newborn son, playing in a charity polo match alongside brother Harry.
William took a break from paternal duties to play in the Audi Polo Challenge at Coworth Park, Ascot, Berkshire.
The charity match is held each year and this year's event was in aid ofcharities SkillForce and The Royal Marsden Cancer Charity, of which William is patron and president respectively.
Today was the first public appearance by William since he left hospital the day after the birth of his son Prince George on July 22.
Yesterday Kensington Palace announced that the birth of the third-in-line to the throne had been formally registered after a registrar from Westminster City Council visited the palace.
William, 31, signed the birth register entry for his son, listing his and wife Kate's jobs as prince and princess of the United Kingdom.
Kate attended last year's Audi Polo Challenge match, along with the couple's puppy Lupo, to support William and Harry, but there was no sign of her today.
She is thought to be at her parents' home in Bucklebury, Berkshire, with Prince George.
RAF search and rescue pilot William is currently on paternity leave but is expected to return to work at some point next week.
He and brother Harry, 28, who yesterday joked about how his nephew's birth had taken the pressure off him to settle down, both played on the four-man Audi Quattro team as they took on the opposition Audi Ultra team.
