The King and Queen were greeted by cheers from well-wishers as they arrived at the wedding of the Princess Royal's son.
Peter Phillips married NHS nurse Harriet Sperling during a private ceremony at All Saints Church in Kemble, Gloucestershire, on Saturday.
Charles and Camilla joined members of the royal family, including the Prince and Princess of Wales, Zara and Mike Tindall and the Duke and Duchess of Edinburgh.
Princesses Eugenie and Beatrice were pictured arriving, alongside their husbands, Jack Brooksbank and Edoardo Mapelli Mozzi.
Members of the public from all over the world travelled to the event and cheered loudly as William and Kate arrived at All Saints Church.
Metal barriers, forming two pens for the media and public, were erected around the church and road closures were in place.
There were shouts of "hip hip hooray" as bride Sperling arrived along with her three bridesmaids, Phillips' children Savannah, 15, and Isla, 14, as well as Sperling's teenage daughter Georgina.
Phillips and Sperling began dating in 2024 after he split with his first wife, Autumn Kelly, in 2020.
The pair's engagement was announced in August last year.
The wedding falls on the same day as the Epsom Derby, with the King and Queen set to travel from the ceremony to the racecourse, ready to watch the highlight of the racing season and present the trophy to the winner.
Pemil, who came to see the wedding with her daughter Adrielle, said: "We're very excited to be here.
"We live in Malmesbury but are originally from the Philippines. I'd like to give these flowers to any members of the royals, but particularly Kate."
Zoe Fraser, another well-wisher, said: "It's very exciting having the royal family coming to your village.
"We've known about it for two or three months. We've had a special litter pick to clean the village up.
"There's been lots of bell-ringing practice, as they're using local bell ringers."
Son of Princess Anne and Captain Mark Phillips, the 48-year-old is 19th in the line of succession to the British throne.
All Saints Church, with its tall spire and quaint brickwork, sits in the heart of the rural village.
