A Contemporary Art Special

Turner Prize-winning artist Grayson Perry presents from the Frieze Art Fair - now one of the most influential contemporary art fairs. He explores the highlights of the show and some of the specially commissioned artworks based on game shows, mobile phone shops and archaeological digs. The Frieze Art Fair has a huge impact on London itself and all the galleries have new shows opening in the same week; Andrew Graham-Dixon talks to Chinese artist Ai Weiwei about his new installation in Tate Modern's Turbine Hall, and Ben Lewis goes on an art safari around the new up and coming galleries of south and east London to find the art stars of tomorrow.
