Four celebrities take on some pint-sized geniuses in a battle of the brains.

Janet – ‘just because they’re kids it doesn’t mean we have to be nice to them’ – Street-Porter, comedian Dom Joly, C4 newsreader Cathy Newman and actor Rob Delaney go head-to-head over five rounds with four of the brightest young minds in the country.

The teams are tested on spelling, memory, maths, a specialist subject and general knowledge.

Will Janet get a cerebral kicking from a nine-year-old?

Will Dom try to distract his young rival to succeed?

The gloves are off as the celebs’ reputations are at risk against these remarkable kids.
