Prince William shares previously unseen photo of Princess Diana for Mother’s Day

“Remembering my mother, today and every day,” the Prince of Wales captioned the Instagram post.

“Thinking of all those who are remembering someone they love today. Happy Mother’s Day. W.”

Princess Diana died aged 36 after a car crash in Paris on August 31, 1997.

Prince William previously reflected on the kind of grandmother he believes his mother would have been in the 2017 documentary Diana, Our Mother: Her Life and Legacy.

He joked that Diana would have adored her grandchildren but might also have been “a nightmare grandmother”, according to Hello! magazine.

“She’d come and go and she’d come in probably at bath time, cause an amazing amount of scene, bubbles everywhere, bathwater all over the place and – and then leave.”

In 2021, he shared heartfelt Mother’s Day cards written by his children to their “Granny Diana”.

“Dear Granny Diana, I am thinking of you on mother’s day. I love you very much. Papa is missing you. Lots of love Charlotte xxxxxxxxx”, Princess Charlotte wrote on a pink card with a large hand-drawn heart surrounded by butterfly stickers.

Her older brother Prince George wrote: “Dear granny Diana, Happy happy Mother’s Day. I love you very much and think of you always, sending lots of love from George xxxxx”.

“Wishing Mothers everywhere, and those who might be missing their Mums today, a restful Mothering Sunday.”
