Here is a video of the couple as they arrived.

The Prince and Princess joined King Charles III and Queen Camilla at the interfaith event, along with other senior members of the Royal Family.
Prince Albert of Monaco was in attendance today, although Monaco is not a member of the Commonwealth. 
The Princess Royal and her husband, Vice Admiral Sir Tim Laurence. 
The Duke and Duchess of Gloucester.
The Duke and Duchess of Edinburgh did not attend as they are in Italy for the 2026 Winter Paralympics. Below, flags of the Commonwealth countries are carried into Westminster Abbey ahead of today’s service.

The Royal Commonwealth Society notes, “Taking place on Commonwealth Day, the service is one of the most significant moments in the Commonwealth calendar, celebrating the shared values, culture and creativity of its 56 member nations.”
More from this story in The Times.
After a fanfare, the national anthem was sung and the royal family processed through the abbey, something of a personal achievement for the King and Kate, who were forced to miss the ceremony two years ago when they were both undergoing cancer treatment.

The service incorporates music, readings, prayers, dance, and other elements. 
The Commonwealth is home to more than 2.7 billion people. 
We return to The Times article for more on the King’s message this year.
In a written message to the Commonwealth, the King described the union as “a force for good” in an “increasingly fragmented” world.
He said: “In a world that can feel increasingly fragmented, this voluntary union of free association remains rare and precious — a forum for open and honest discussion and debate to help improve the lives of the nearly three billion people who call our member states home. Our Commonwealth of Nations hold untapped potential for prosperous trade between trusting partners.”
Former Spice Girl Geri Halliwell-Horner spoke at the service.
More from The Evening Standard’s story.
In her “reflection” Halliwell-Horner highlighted how International Women’s Day fell on Sunday, one day ahead of Commonwealth Day events, and told invited guests: “As a young girl, it was creativity and education that gave me courage and confidence.
Halliwell-Horner, an ambassador for the Royal Commonwealth Society, which held the service, and the King’s Trust, said in her speech: “The Commonwealth at its best is a family of equals, different, yes, but connected by shared values and a shared responsibility.
The Telegraph reports the Princess seemed particularly interested in some of today’s dancing.
The Princess of Wales seemed particularly interested in a Bollywood and ballet dance performance by Sapnay Entertainments and the Royal Ballet in the Abbey aisles. She told dancers she had “wondered what the marble [floor of the Abbey] was like with bare feet”, adding that it was “such an amazing venue” to see them perform in.
After its conclusion, Royal Family members spoke with those who took part in the service. 
The Princess received flowers as she left the Abbey with Prince William.

Another view of the Princess outside the Abbey this afternoon. 
The Queen wore a vibrant red coat and dress by Fiona Clare, accessorized by a Philip Treacy hat. Her Palm Leaf Brooch by Cartier was created for The Queen Mother in 1938. 
The Princess Royal was in a coat I have seen described as British racing green and Edinburgh green, the color used by her father, Prince Philip, for his livery. She wore a diamond brooch believed to have been a gift from her parents for her 18th birthday. The Duchess of Gloucester was in navy with a red scarf, dress, and hat, with diamond and ruby earrings. 
Now, we turn to our look at what Kate wore, starting with her Catherine Walker coat. 
The design showcases a tailored bodice with peaked, padded shoulders, a full skirt with pleats descending from the hips, princess seaming, and flared cuffs. The garment incorporates elements of Catherine Walker’s Amarante and the Courchevel styles. 
The Princess brought back the Sean Barrett bespoke navy saucer hat, first seen at the 2023 Commonwealth service, updated with matching netting. 
She owns the style in three colors. 
She carried her Multrees Chain Wallet ($425) in croc-embossed navy by Scottish accessories maker Strathberry. It measures roughly 8″ x 4″ and has a removable chain strap so it can be carried as a clutch.
We saw the return of the Gianvito 105 in navy suede. The style is available at Gianvito Rossi ($850) and Farfetch ($795). 
The Princess also wore the Bahrain Pearl Drop Earrings, part of a wedding gift from the ruler of Bahrain to Princess Elizabeth.
More from Tatler’s coverage.
The Bahrain Pearl Drop Earrings were created by the then Princess Elizabeth from a cache of seven pearls, which she received as a wedding present in 1947 from the Hakim of Bahrain. The earrings are comprised of round diamond studs, from which are suspended round and baguette-cut diamonds in an Art Deco style, plus two of of the Bahrain pearls.
The Princess also wore her Susan Caplan Vintage 5-Strand Faux Pearl Necklace (£275, about $370 at today’s exchange rates). The necklace features five strands of faux pearls in graduated sizes.
The product description notes, “This is a slight colour variation of our original 5-strand necklace worn by Princess Kate. Our pearl necklaces are custom-made using original vintage faux pearls and with Swarovski crystal embellished clasps.” The necklace is now also available at Farfetch ($482) and Nordstrom ($535).
I will see you on Thursday, when the Prince and Princess visit the RNLI Tower Lifeboat Station located on the River Thames. Until then, here is one more photo from today.
