In a year when all eyes are on London, Matthew Sweet explores London's place as a world city, and asks if London really is the centre of arts and culture it claims to be. He discusses this with Neil O'Brien of the think tank Policy Exchange and Aditya Chakrabortty of the Guardian at Tower Bridge. At the South Bank Centre Matthew meets with its artistic director Jude Kelly, the novelist Lesley Lokko and the culture editor of Monocle, Robert Bound. And he finally talks to Radio 3 New Generation Thinker Nandini Das and also to the 'Gentle Author' of the Spitalfields Life blog.
