Rachel Annabelle Riley

Television
In January 2009, Riley replaced Carol Vorderman as the co-host of Countdown doing the letters and numbers selection and mathematics solutions. She hosts the show alongside Nick Hewer. Riley has co-presented over 1,000 episodes of Countdown.
Riley was encouraged to apply for the Countdown position by her mother. She did not have an ambition to be a television presenter, but decided to apply because she was interested in the numbers part of the game. Riley was chosen from more than a thousand applicants despite having no television experience. In an article for BBC News, she said, "There's only one cool maths job around and I was lucky enough to get it so I'm absolutely thrilled".
