On Start the Week Mary Ann Sieghart takes a satirical look at the world with the novelist Jonathan Coe. His latest book is a state-of-the-nation satire which takes aim at politics, social media and inequality. It's the battle between ideals and pragmatism in the cynical world of the political elite of the 1920s which takes centre stage in the play Waste, famously banned when it was first written, now revived and directed by Roger Michell. The Times' political cartoonist, Peter Brookes, celebrates the power of the visual image to lampoon the country's leaders and the playwright Mia Chung explores whether satire can do justice to the questions raised by a regime like North Korea and talks about her latest play about two sisters fleeing the country.
