Max Pearson presents a collection of this week's Witness History episodes from the BBC World Service. Our guest is Ozoz Sokoh, Nigerian food writer and author of the Kitchen Butterfly food blog, who tells us about the history of West African food.

The programme begins with the story of Mr Bigg's, Nigeria's answer to McDonald's. Then, we hear about the 1960 coup against the Emperor of Ethiopia, Haile Selassie, from his grandnephew.

In the second half of the programme, a Jewish survivor tells us about the Nazi occupation of Greece from 1941-1944. Two witnesses tell us about Pope John Paul II's ill-fated visit to Nicaragua in 1983. And a Pakistani man recounts how he accidentally created the first personal computer virus in 1986.
