All four series of the BBC Radio 4 comedy panel show about morality and ethics, hosted by Sue Perkins - plus a special episode recorded at the Edinburgh Festival FringeDescribed by the Radio Times as 'a cross between QI and The Moral Maze', this hilarious and thought-provoking panel show sees comedian Sue Perkins putting her guests through the moral and ethical wringer as she poses a series of tricky hypothetical questions - and cross-examines them on their answers.Would you provide an alibi for someone you hate? Would you let an annoying colleague take credit for your work if it meant they would get a job elsewhere? Is cheating on your partner ever acceptable? These are just some of the devilish dilemmas facing the panellists - and as if that's not tricky enough, there's also a variety of rounds including Audience Dilemmas, where they 'solve' any problems the audience may have, and Quickfire, where shades of grey are dismissed in favour of a fingers-on-buzzers binary choice, such as 'Would you rather eat a kitten or fight a swan?'Among the panellists tiptoeing through the moral minefield in these four series are comedians Dave Gorman, Shappi Khorsandi, John Finnemoreand Graeme Garden; radio DJs Annie Nightingale, Shaun Keaveney, Cerys Matthews and Gemma Cairney; poets Lemn Sissay and Ian McMillan and sports stars Isa Guha and Clarke Carlisle, as well as historian Dan Snow and former Blue Peter presenter Janet Ellis.Plus, a special Edinburgh Festival Fringe edition features guests including Marcus Brigstocke and Bridget Christie, and subjects including disabled parking spaces, adverts, and life imprisonment.
