Catherine, Princess of Wales' annual Christmas carol concert will be themed around how much people "need each other, especially in the most difficult times."
The 42-year-old royal - who is making a gradual return to public life after undergoing abdominal surgery followed by preventative chemotherapy earlier this year - will host her 'Together at Christmas' event on 6 December at London's Westminster Abbey and this year, the service will examine the "importance of love and empathy".
The list of guests to be invited is designed to “shine a light on individuals from all over the UK who have shown love, kindness and empathy towards others in their communities”.
A Kensington Palace spokesperson said in a statement: “This year’s service provides a moment to reflect upon the importance of love and empathy, and how much we need each other, especially in the most difficult times of our lives.
“The service will shine a light on individuals from all over the UK who have shown love, kindness and empathy towards others in their communities.
“This year, Her Royal Highness wanted to celebrate the many people supporting those in need – individuals who have inspired, counselled, comforted, and above all else shown that love is the greatest gift we can receive.
“This theme takes inspiration from the Christmas story which encourages us to consider the experiences of others and the important human need of giving and receiving empathy.”
Around 1,600 people will attend the service, including members of the royal family, with other guest names nominated by various charities and Lord Lieutenants.
Musical performances will come from the likes of Paloma Faith, Olivia Dean and Gregory Porter, while decorations at the abbey will be inspired by nature.
In addition, 15 'Together At Christmas' community carol services will take place at various locations in the UK, including the Royal Cornwall Hospital in Truro and Blackpool Tower Circus, and recognise those who have gone above and beyond to help others.
The 'Together at Christmas carol' service will broadcast as part of a special programme on ITV1 and ITVX on Christmas Eve (24.12.24).
