On Start the Week Andrew Marr talks to the playwright Ben Power whose latest work interweaves three of DH Lawrence's dramas to evoke a lost world of manual labour and working class pride. The sociologist Mike Savage proposes a new way to think about class in Britain which not only looks at economic and social issues, but cultural preferences. Meanwhile the American writer Siri Hustvedt questions the cultural misogyny at play in the world of art, and Peter Davies celebrates the artists inspired by the northern industrial landscape.Producer: Katy Hickman.
