How do dictators and authoritarians stay in power? James Tilley, a professor of politics at Oxford University, finds out what's in the dictators' survival guide. How do they control ordinary people and stop revolts? How do they stop rivals from taking over? And how do they manipulate apparently democratic procedures like elections - such as the notoriously fraudulent 2004 vote in Ukraine - to secure their rule? This is another chance to hear a programme, originally broadcast in 2018, that has acquired new relevance.
