Edward Sebastian Vulliamy is a British-born, Irish-Welsh journalist and writer.

World in Action was a British investigative current affairs programme made by Granada Television for ITV from 7 January 1963 until 7 December 1998. Its campaigning journalism frequently had a major impact on events of the day. Its production teams often took audacious risks, and the programme gained a solid reputation for its often-unorthodox approach. The series was sold around the world and won numerous awards. In its heyday, World in Action drew audiences of up to 23 million in Britain alone, equivalent to almost half the population.
