Ahead of her LRB lecture at the British Museum, we talk to Mary Beard about women in power. Why are powerful women so often called phonies? What can we learn about women and power from the ancient world? We discuss what's wrong with the idea of glass ceilings, and what Hillary Clinton's treatment at the hands of Trump and his supporters really says about political misogyny. Plus Mary tells us what she thinks has gone wrong with the Labour party. On that note, we also have Helen and Chris looking ahead to this week's by-elections: who has most to lose, Corbyn or UKIP?
