“That’s the Judicial Process.”

Kate Adie introduces dispatches by: Yolande Knell in Qaraqosh, who observes Iraq's trials of people accused of fighting for so-called Islamic State; Martin Patience, who takes his leave of Nigeria with mixed emotions after a two-year stay; Matthew Hill in Sri Lanka, who finds that the strains and tensions between those who govern and many of those whom they govern are intensifying; Harriet Constable, who reports from Kenya on the increasingly violent and costly incidence of sand harvesting; and Hywel Griffith visits one of Australia's many micro-nations to meet the white-bearded Prince Paul of Wy to discover why he has set up his own realm.
