The 2022 season of the general knowledge quiz reaches its climax, with the four most formidable of this year's contenders now within reach of the Brain of Britain title. Whether by impressive margins or by the skin of their teeth, they have seen off all comers in heats and semi-finals. Now it will be down to the breadth of their knowledge, and their reaction time on the button, as they face the final challenge before an eager audience at the Radio Theatre in London.

The contenders for the title are:
Marianne Fairthorne from London
Isabelle Heward from Goxhill in Lincolnshire
Emma Laslett from Milton Keynes
Sarah Trevarthen from Manchester.

Only one of them can take away the silver trophy as the 69th official Brain of Britain.
