The Princess of Wales is hosting her annual Yuletide celebration at Westminster Abbey, with guests including royals, celebrities and local heroes who have made a difference in their neighbourhoods.
The 1,600 guests will enjoy a selection of festive songs, musical performances, and spoken word pieces from actors such as award-winning actors.
The focus of the concert, held in the candle-lit Abbey on Friday afternoon, is compassion and demonstrating care for others.
Attending the event are a couple named the Cordiners, whose child passed away from a tumour, and who founded an organisation, Kayleigh's Wee Stars, to aid parents with a terminally ill child.
"The time, care and compassion you give, often quietly and unspoken, and without any hope for reward or acknowledgement, make an remarkable change to the circumstances of individuals," wrote Catherine in a message before the concert.
The Princess of Wales is continuing her own steady comeback to official duties after her cancer diagnosis and chemotherapy, recently giving her major oration since 2023, in which she reflected on recognising the "quiet, often invisible work of caring".
Guests arriving at the Abbey can listen to young musicians aided by the charitable trust Future Talent, set up with the help of the late Duchess of Kent to broaden opportunities for instrumental training.
Trumpeter Carys Wood, 18, who is a trumpet player and is from Pembrokeshire, has been supported by the charity, with awards contributing to instruments, tuition, and transportation expenses - and she said it was "amazing" to be taking part in tonight's service.
"Pursuing music is often costly," the musician remarked. She is now studying at the renowned conservatoire, and added that "everyone should have the opportunity" to develop their musical skills.
Eliza, Carys's sister who is 11, who performs on the brass instrument, will be present at the Abbey. "It's unbelievable that I get to perform here in front of so many important people," she said.
Attending the service will be representatives of different generations.
That will include nine-year-old Saphia Turner, winner of a prize for youthful altruism, who sells artwork and carries out sponsored challenges to collect donations for local food charities.
The Abbey has been festooned with custom-created holiday decorations, with celebrity baker Mary Berry and floral designer Simon Lycett contributing to their design.
Taking to the stage will be recording artist Katie Melua, the Abbey's own choir and a maritime folk band from Cornwall, the Fisherman's Friends, who said the invitation to sing was "a dream come true."
This annual carol service will be broadcast on television on December 24th.
