In a special programme on BBC Radio 4, London is pitted against 3 other cities in 'I love..? The Great Cities Debate' What is it about certain cities that inspire such devotion? Be it London, New York, Mumbai, Istanbul.. In a lively and passionate debate in front of a studio audience, four advocates make a pitch for their chosen city. Under the close scrutiny of the presenter, Laurie Taylor, they will extol the virtues of the city's architecture, literary heritage, political influence and unique temperament. The novelist Jake Arnott celebrates the idiosyncrasies of London, while Nikki Bedi makes a plea for the vitality of Mumbai; the writer Maureen Freely takes listeners on a journey down the Bosphorus, and the stand-up comedian Lewis Schaffer argues that New York's pre-eminence is no joke. Four city-lovers will seek to beguile and cajole as they try to win the title of the most loved and greatest city of them all.
