Max Pearson presents a collection of the week's Witness History interviews from the BBC World Service about the Vietnam War and the invention of the hugely popular mobile phone game, Snake.

Don Anderson, a former BBC TV reporter during the final days of Vietnam, discusses the atmosphere in Saigon as the North Vietnamese forces closed in.

We also hear about the network of tunnels in the south of the country which Viet Cong guerrillas built during the fighting.

Finally, the former president of the European Commission and two-time prime minister of Italy, Romano Prodi on steering through the ten-state expansion of the European Union in 2004.
