Invisible ink, delayed flights and political meddling - elections are a symbol of democracy, so how can they become the opposite?

Don is joined for this episode by Brian Klaas, co-author of 'How to Rig an Election' to find out. What makes a free and fair election? What techniques have authoritarians used to have themselves elected? And how widespread has this been throughout history?

Brian is a political scientist, a contributing writer at The Atlantic, and an associate professor in global politics at University College London.
