Each year, royal fans eagerly await the arrival of the royal family at a pre-Christmas luncheon at Buckingham Palace. While onlookers only get a brief glimpse of the attendees' attire as they arrive at the palace by car, the annual event is a star-studded affair. This year, however, Kate Middleton and Prince William may not attend.

Before the COVID-19 craze, the Royal Family's pre-Christmas luncheon was always held at Buckingham Palace. After a brief hiatus, it resumed in 2022 and was held at Windsor Castle instead; in 2024, Prince Charles has reportedly decided to hold the luncheon at Buckingham Palace again, which could cause problems for the Prince and Princess of Wales.

Kate and William's attendance depends on whether they have already moved to their Anmer Hall residence in Norfolk for the vacation, Hello! reports. If they decide to leave their Windsor mansion a few days before Christmas, the Prince and Princess and their three children will likely miss Prince Charles and his family's events.

The annual event will be attended by the Duke and Duchess of Edinburgh, Princess Anne, Mike and Zara Tindall, Princess Beatrice, and Princess Eugenie.

On December 10, Prince William attended a Christmas party at the 1st Battalion, Mercian Regiment, and told The Sun of his modest Christmas plans to “spend the Christmas period in Norfolk, taking long walks with the family dog.”

There are many rules that are generally adhered to regarding how the royal family traditionally celebrates Christmas. Former BBC royal correspondent Jenny Bond explained to The Sun's Fabulous magazine that “I can't imagine the royal family lying on a set table in slippers and slouch pants, guzzling booze and chocolate like we do.” She continued. A certain amount of decorum is still required.”

Importantly, Royal Family guests are expected to be on time for the feast. 'They do not come to Sandringham when they feel like it. 'Invited guests should arrive at the expected time, not before or after.'
