At the helm once again is Sandi Toksvig, joined by Alan Davies as they both lead a dazzling mix of first-time guests and returning favourites who wrestle with the Weird and Wonderful, dabble in Wordmongery, puzzle over Who, What, Why and unravel all manner of Whatnots.

From Veggies to Visionaries, this series is packed full of Varied and Vibrant subjects that are bound to fascinate, challenge and entertain.
