Naji al-Ali was one of the best known cartoonists in the Arab world. His creation, a little boy called Handala, always stands with his back to the viewer, hands behind his back, watching whatever Naji al-Ali has drawn. He's been picked by the Pulitzer prize winning data journalist Mona Chalabi - but is she picking the artist, or his creation, the observant little boy?

Joining Mona in studio to discuss a life that was cut short is the cartoonist Martin Rowson. Naji al-Ali was assassinated in London in 1987 at just fifty years of age. The case remains unresolved. A powerful programme that includes the voice of Naji al-Ali's son plus news archive from 1987 and 2017, the thirtieth anniversary of his death.
