On Start the Week Andrew Marr asks how the arts tackle politics and current affairs. The performer Rory Bremner turns his comedic eye to opera, in an updated version of Offenbach's Orpheus in the Underworld. Originally written to satirise Napoleon III's Paris, Bremner draws present day parallels with a spin-filled, celebrity-obsessed world. For the last 30 years the film maker Peter Kosminsky has turned conflicts from Bosnia, to the Falklands, and Israel/ Palestine, as well as the story of New Labour, into drama and documentaries for television. In 1939 the Whitechapel gallery in London was the space chosen to show Picasso's overtly political work, Guernica. The gallery's present director Iwona Blazwick talks about how artists have reflected the political and present day concerns. And the singer/ songwriter Sarah Gillespie argues that the key to a good protest song is to harness the experience of the individual.
