Today’s sixth Christmas guest editor is Anne-Marie Imafidon – computer scientist, CEO and co-presenter of Countdown.

Hear highlights of her programme, whose central theme is opportunity. She looks at how we work, how we fund science, and how we recognise the achievements of women which have been lost to history, such as Dr Gladys Mae West, whose maths work paved the way for GPS navigation.

We also explore two of Anne-Marie’s big passions – Nigerian food and trainers.
