Prince William has made a rare public admission about his feelings following the death of Princess Diana, telling a grieving boy he was "very angry" when his mother died.
William's candid comment came at the start of a year that will mark the 20th anniversary of her death.
He spoke openly during a visit to an east London bereavement centre with his wife, where they sat down with families making memory jars in honour of a loved one who has died.
As Lorna Ireland and her 12-year-old son Shinobi Irons filled their individual jars with bands of coloured salt - representing memories of the youngster's grandmother who died three years ago and godmother who died in 2015 - the future king spoke about his feelings.
He told my son that when his mum died he was 15 at the time and he was very angry and found it very difficult to talk about it," Ireland said.
"So it was very important that Shinobi talked to somebody about how he was feeling even now years on.
"It was very personal and it was very special."
The Duke of Cambridge was a teenager and his brother Prince Harry was just 12 when their mother Diana was killed in a car crash in Paris on August 31, 1997.
In recent years the royal siblings have begun to talk about their feelings surrounding their loss with Harry saying last summer in an interview he now regrets not opening up sooner about how his mother's death affected him.
