The brother duo would be seen stepping out alongside their parents, King Charles and Princess Diana, as well as their cousins, including Zara Tindall, Peter Phillips, and their royal aunts and uncles.
Whilst the pair haven't spent the day together since Harry and Meghan gave up their royal roles and left the UK back in 2020, Harry and William shared many wonderful Christmas moments together.
One particularly adorable snap saw Harry and William in 1996 admiring the gifts they were given by members of the public. Fifteen-year-old William was showing his 12-year-old brother the large golden Toblerone he had received.
The large chocolate was adorned with the words: "Ho ho ho" in red lettering. Meanwhile, Harry was carrying a festive gold gift bag covered in red Christmas trees.
