Prince William has made his first appearance in public since the birth of his son, Prince George Alexander Louis of Cambridge. The Duke of Cambridge was at a charity polo match, where he was joined by his brother Prince Harry.

The royal brothers were at the Audi Polo Challenge at Coworth Park in Ascot.

Audi UK director Martin Sander presented the 31-year-old William with a mini polo mallet for his newborn son.

William, who reportedly has been singing rock band Coldplay's tracks to get Prince George to sleep, jokingly asked if it was nappies, adding, "I've got to pick some up on my way home."

He also admitted it was "good to get out of the house" for an afternoon and added "I've got to make sure I'm not too late back."

William, who scored the winning goal for his team in the match, said of his performance: "I was in baby mode out there, thinking about nappies, I wasn't really in the zone."

Kate Middleton, the Duchess of Cambrige, gave birth to George on 22 July, in the Lindo wing of London's St Mary's Hospital. The young prince is third in line to the throne.

The duke, who is on paternity leave from his job as an RAF search and rescue pilot, said his son "likes to move around a lot, he wriggles a lot, he keeps us on our toes".

The 11th annual polo match will raise money for charities SkillForce and the Royal Marsden Cancer Charity, for which William is patron and president.
