The Royal Family are out in force today for the annual Commonwealth Day service at Westminster Abbey.
Marking the event for the first time since becoming Monarch, King Charles is joined by wife Queen Camilla, his oldest son Prince William and the Princess of Wales.
Prince Edward and Sophie, who last week became the new Duke and Duchess of Edinburgh, and Princess Anne and her husband Tim were also in the procession.
However many royal watchers were disappointed to not see Prince George, Princess Charlotte and Prince Louis.
William and Kate have started bringing their two older children to more royal engagements recently, including events to mark the late Queen's death in September last years and Christmas celebrations.
While Kensington Palace hasn't officially confirmed why the Wales children aren't in attendance, the timing of the event would have clashed with school.
George, Charlotte and Louis has been pupils at Lambrook School in Berkshire since September, joining when the family moved from London to Windsor.
While the school had Friday off, today is a normal Monday for pupils.
George, Charlotte and Louis have stolen the show at recent events they've attended, with little Louis's facial expressions and excitement remaining a highlight of the Platinum Jubilee celebrations last year.
The Commonwealth Day theme for 2023 is Forging a Sustainable and Peaceful Common Future, and comes at a time when Charles has experienced great turbulence in his relationship with his youngest son, the Duke of Sussex.
Prince Harry and Meghan Markle will also miss the event, as they are now living in the US with their children Archie and Lilibet. There is still much discussion about whether they will return to the UK for the King's Coronation later this year.
King Charles became head of the Commonwealth since his mother passed away last year.
The service, broadcast on the BBC, includes musical performances from saxophonist Yolanda Brown, West End stars Roshani Abbey and Nuwan Hugh Perera, and the all-female Amalgamation Choir, from Cyprus.
Guests of honour among the 2,000-strong congregation will include the Commonwealth secretary-general, the prime minister of Samoa, high commissioners, senior politicians and dignitaries from across the UK and the Commonwealth.
Also attending will be athletes from the home nations who competed at the Commonwealth Games in Birmingham last summer, as well as faith leaders, and more than 750 schoolchildren and young people from throughout the UK.
