My husband, Marshall Stewart, who has died aged 88, worked in broadcasting for 50 years, first within BBC radio and then in independent TV and radio.
In 1970 he took over as editor of the BBC Radio 4 Today programme, transforming it from what its presenter Jack de Manio had described as a “lighthearted miscellany” into a hard-hitting current affairs programme, and introducing the acerbic Robert Robinson as a co-presenter with John Timpson.
