Prince William has shared a subtle but touching tribute to his mother, Princess Diana, more than 24 years after her death.
Taking to the official Duke and Duchess of Cambridge Instagram, the future king shared a series of photos from a recent event he attended with The Passage charity in the UK.
The group provides services to support getting homeless people off the streets for good and has been doing this "life changing" work for 40 years now.
The Duke of Cambridge paid tribute to the charity's incredible work over the decades, writing: "Over the many years that I have visited The Passage, first with my mother when I was just a small boy, I have developed a great affection for you all.
"Every time I come here, I am touched by the warmth and friendliness, and the dignity and respect you show to everyone who comes through your door."
As well as mentioning his late mother in the caption, William included a subtle photo tribute to his mother tucked away in the carousel of photos.
He included a black and white image of the late Princess of Wales meeting with individuals The Passage supported.
The photo he chose shows Diana sitting across from a man in a heavy jacket and beanie, listening closely as he speaks.
"I am always so impressed to see and hear the difference that The Passage makes to the lives of people who are experiencing homelessness," William continued in his caption.
"Thank you to everyone for your continuous work. W"
The duke has been The Passage's royal patron since 2019 and has been passionate about the group's charitable work after seeing Diana support it during her life.
A staunch supporter of many charitable and humanitarian efforts, Diana continued to support organisations like The Passage even after she left the royal family.
Diana has been quoted as saying of her charitable efforts: "Nothing brings me more happiness than trying to help the most vulnerable people in society.
"It is a goal and an essential part of my life—a kind of destiny. Whoever is in distress can call on me. I will come running wherever they are."
It's a sentiment Prince William appears to be carrying on through his own work with charities like The Passage and other organisations he supports.
This year he and brother Prince Harry marked what would have been their mother's 60th birthday, as well as the 24th anniversary of her death.
To mark the former, the brothers joined at Kensington Palace to unveil a new statue built in their mother's honour.
"Today, on what would have been our mother's 60th birthday, we remember her love, strength and character – qualities that made her a force for good around the world, changing countless lives for the better," they said in a joint statement.
"Every day, we wish she were still with us, and our hope is that this statue will be seen forever as a symbol of her life and her legacy."
