Duke of Cambridge and Family Enjoy a Day of Equestrian Fun at the Polo

The Duke of Cambridge, Prince William, was joined by his young family for a day of equestrian fun at the polo.

The 35-year-old prince competed in the Maserati Royal Charity Polo Trophy at Beaufort Polo Club in Gloucestershire, just a day after participating in the show-stopping Trooping the Colour Parade in London.

On Sunday afternoon, his wife, Kate Middleton, delighted fans with a surprise appearance as she, along with their children George and Charlotte, descended on Tetbury for a day of family fun.

Dressed casually in a £39.99 Zara dress and Russell and Bromley wedges, Kate looked every inch the doting mother as she kept a watchful eye on George, 4, and his cousins Isla and Savannah Phillips.

At one point, mischievous Charlotte made Kate and Autumn Phillips collapse into fits of giggles as she performed an impressive headstand, while a shy George watched on.

George was no doubt delighted to be reunited with his cousin Savannah, who on Saturday was pictured cheekily covering his mouth with her hand as they watched the Red Arrows fly past from the balcony of Buckingham Palace.

The Prince, an experienced polo player, looked strapping in his gear, picking up his mallet and helmet before showing his dexterity as he rode around the pitch.

Today's charity match will help raise funds and awareness for two charities, the Royal Marston, which the Duke supports as President, and Centrepoint, of which he is patron.

The match, which will see the Maserati team take on the Domani 1969 side, is part of the two-day Gloucestershire Festival of Polo, hosted by Beaufort Polo Club from 9 to 10 June.

Tickets cost up to £150 a head for the event, described by organisers as a special day out and featuring rural demonstrations, an attended shopping village and traditional funfair.

The first day of the event, a highlight of the equestrian calendar, was attended by the likes of Carol Vorderman, Lisa Maxwell and Richard Hammond.

Sunday's match is part of a series of charitable polo matches that the Duke and Prince Harry will play in the summer.

The two brothers have taken part in polo fixtures in support of their charities since 2007, and have continued each year since, raising over £11 million for charitable causes to date.

Today's appearance is one of William's first since becoming a father for the third time in April, and Harry's first since returning from his mystery honeymoon with Meghan.

The brothers' love of all things equestrian runs in the family, with several members having represented Great Britain at international level.

Their aunt Princess Anne and cousin Zara have both competed at the Olympics in eventing, with Zara earning a silver medal with the British team.
