The broadcaster obtained a second-class degree in applied maths at Oriel College, Oxford.

Discussing Tom, Rachel told Metro: “Countdown viewers are in great hands with Tom, who is a brilliant Mathematician and a lovely guy.
“He’s also used to people commenting on the clothes he wears (or lack of them) on his show so I am sure he will take to the role like a duck to water.”
Dr Tom added: “All of my work online is about sharing my love of Maths with the world whilst trying to make it accessible for everyone.
“Countdown has been doing that for a generation, so it really is a dream come true to be joining this iconic show to cover Rachel.
