The proceeds will be distributed among 10 organisations supported by both William and Catherine

The Prince and Princess of Wales generated more than £1million for charitable causes at the DMMI Royal Charity Polo Cup held at the Guards Polo Club in Windsor this afternoon.

Prince William competed on the winning side during the match, which took place on a sweltering day at the venue near the couple's home at Forest Lodge.

Catherine, dressed in a black and white gingham Temperley London sundress, watched from the sidelines before presenting trophies to all participants.

After handing her husband his team's victory prize, the princess kissed William on both cheeks in an affectionate moment captured by photographers.

The royal couple then strolled hand in hand back across the pitch following the ceremony, with the day's fundraising reaching £1,050,000.

This marked the future king's 15th appearance at the annual competition, during which he has helped generate a cumulative £15million for various charitable organisations.

William played in his customary defensive position at number four alongside teammates including former England captain Mark Tomlinson, Saudi businessman Amr Zedan, and Leicester City chairman Aiyawatt Srivaddhanaprabha.

Commentator Karl Ude Martinez reminded spectators of the Royal Family's deep connection to the sport, noting that King Charles, the late Duke of Edinburgh, and previous generations had all competed at high levels.

"He doesn't get time to play at all, really, because of his commitments and his busy schedule," Mr Martinez told the crowd. "To have him here today to play is truly a very, very rare occasion."

The proceeds will be distributed among 10 organisations supported by both William and Catherine.

For the first time this year, Evelina London Children's Hospital, one of Catherine's patronages, will receive funding from the event.

The hospital has ambitious plans to establish a specialist cancer treatment facility for young patients across London and the South-East, with an anticipated opening in 2030.

Gubby Ayida, the hospital's chief executive, told the Mirror: "It's absolutely huge, and we are really honoured to be a beneficiary of something like this. The timing could not have been better as next year we are looking forward to opening our new principal treatment centre, which is specialist cancer services for children."

Catherine visited the hospital on Monday, meeting with medical staff developing the centre and speaking with parents of young patients.

Ms Ayida praised the princess's natural rapport with children, describing her as "a ray of sunshine" for staff during challenging times in the NHS.

The Passage, a homelessness charity with deep personal significance to William, is among the beneficiaries.

The prince first visited the organisation aged just 11 and has since made ending homelessness a central focus of his public work through the Homewards campaign, which aims to make homelessness "rare, brief and unrepeated."

Mick Clarke, chief executive of The Passage, told the Mirror: "Especially in this cost of living crisis, it is great to know that we have this money coming in that will be used to help prevent and end homelessness."

Mr Clarke revealed that William frequently makes unannounced visits to the charity without media present, preferring to contribute practically.

"There's nothing he loves more than putting the marigolds on and doing the washing up and helping out - I think that's what he loves the most," Mr Clarke said.

Wales Air Ambulance, which is marking its 25th anniversary this year, also features among the organisations receiving support from the polo cup.

Dr Sue Barnes, the charity's chief executive, expressed gratitude for the contribution, explaining the significant costs involved in their operations.

"We are amazingly grateful. What we do is expensive, and our average mission cost is about £3,500, so we need to raise over £30 million a year just to keep going," she told the Mirror.

Dr Barnes highlighted William's particular affinity with the service, stemming from his previous role as an air ambulance pilot.

"Supporting us is a real passion for him, and with him previously being an air ambulance pilot, he's part of the family," she said, adding that the prince regularly drops into crew rooms to check on staff when passing their bases.
