Graham Walker, who edited The World Today with distinction for 15 years until 2010, has died after a short illness.
Taking over the editorship of the magazine was the summit of a long journalistic career. After studying sociology and economics at the University of Leicester, he went travelling in Africa and by 1970 he was teaching a course in mass communications at the University of Witwatersrand while contributing articles to the Rand Daily Mail.
A stint in Hong Kong led to work at Channel 4 News, where he became foreign editor and then bureau chief for Independent Television News in Johannesburg. It was in South Africa in 1986 that he married his Austrian wife Gabriella in a ceremony presided over by Bishop Desmond Tutu.
Under his editorship, the Channel 4 foreign affairs programme, The World This Week, developed a lively, irreverent style which won bronze and then gold medals at the New York Film and Television Festival.
