Richard Osman is said to be an early favourite to replace Anne Robinson on Countdown after she confirmed she was stepping down as host.
On Monday, 77-year-old Anne announced that she was quitting her position on the Channel 4 quiz show as she wants to spend more time with her grandchildren.
Anne, who recorded 265 episodes of the show, said of her decision to quit: "I've had a blast hosting this wonderful show. And I stayed longer than I signed up for. Now it is time for an older woman to take the reins.
