Gyles Brandreth presents the quiz without questions.

Contestants have their breadth of knowledge tested to the limit as they battle it out to impress the show's experts. Two teams are given their topics and then have just one hour to prepare. Without any outside help, they have to pool everything they know, and then face the Knowitall experts. The categories are travel and geography, food and drink, and art and literature.

The winners go through to the quarter-finals and are one step closer to the prize of 15,000 pounds and the title of Britain's Biggest Knowitalls. Show less
