Viewers were left in stitches after a contestant on Tipping Point said that a former Labour party deputy leader was Agatha Christie.
Ben Shephard asked Dave, the contestant "'Downsizing, How I Lost 8 Stone, Reversed My Diabetes And Regained My Health' is a book by which former deputy leader of the Labour party?"
Dave looked confused, and answered "The only name that's come into my head, and I don't know why, is Agatha Christie and I don't even know if she's in politics".
