He became a journalist and broadcaster after the Second World War and joined the BBC in 1957.
Alan Whicker was one of the most widely-travelled and popular broadcasters of his generation.
For more than 40 years he roamed the world for the BBC and independent TV networks, seeking out the eccentric, the ludicrous and the socially revealing aspects of everyday life from all over the globe.
Whicker's World, his documentary programme, ran from 1959 to 1990.
He acquired over the years an enviable reputation of having no equal as a television commentator.
