It was no secret that Princess Diana detested the royal family’s annual Christmas celebrations at Sandringham, and a new program features royal biographer Ingrid Seward and longtime royal photographer Arthur Edwards revealing that Diana used to duck out of Sandringham as quickly as she could to get back to London.

Here's why Princess Beatrice and Princess Eugenie are skipping Christmas in Sandringham with the royal family.

As the Royal Family prepares to gather at Sandringham for the holiday season, two royals won't be in attendance. According to a new report, Princess Beatrice and Princess Eugenie will miss the traditional royal Christmas celebration in favor of their own low-key plans.

Not everyone loves the idea of a Christmas stacked to the brim with tradition after tradition, and for Princess Diana, the thought of enjoying the holidays with her fellow royals at times made her feel so uptight that she would often ditch the festivities as soon as she possibly could.

Although the late Diana, Princess of Wales reportedly disliked her husband's then-mistress Queen Camilla, both of King Charles III's wives apparently liked to ditch Sandringham House early after Christmas lunch.
