Photographer Anwar Hussein and his two sons, who have travelled the world with the royals, are displaying their remarkable images of Princess Diana and her family.
The exhibition in London includes snaps from Anwar's sons Samir and Zak alongside their accounts of the stories behind each picture.

Diana was captivated by this photo of her cradling a child cancer patient in Pakistan in 1997. Anwar remembers tears in her eyes as he took the picture.

A visit to India's Taj Mahal in 1992 did not go to plan for Charles and Diana because he had other engagements – so the Princess was pictured there alone.

Wearing an elegant cream dress, Diana crouched to clasp the hand of a so-called “Untouchable” – considered the lowest in India’s ancient caste system. This photo is from February 1992.

On the night in 1994 that Charles admitted to cheating on her, Diana bravely attended a Vanity Fair party in this figure-hugging outfit which became known as her “revenge dress”.
