As a broadcaster, Michael O’Donnell, who has died aged 90, was a popular presenter and panellist. On Radio 4 he reined in the verbal antics of Frank Muir and Denis Norden as chair of My Word! (1983-92), participated in Robert Robinson’s discussion programme Stop the Week (1976-92) and explored changing social attitudes by interviewing families of all sorts in Relative Values (1987-97).
On television he was a passionate and knowledgable presenter of health documentaries, as I found when producing Cross Your Heart and Hope to Live (1975). This was followed in the 1980s by four O’Donnell Investigates... programmes on food, drink, the food business and ageing, and in the 90s by several on belief and superstition.
