YouTube artist on Turner Prize list

A video artist who uses YouTube clips, a print-maker and an artist who pairs spoken word with photography are among this year's Turner Prize nominees.

Duncan Campbell, James Richards, Ciara Phillips and Tris Vonna-Michell are on the shortlist for the prestigious and provocative contemporary art prize.

Between them, they employ audio, video, craft and design - but there are no traditional painters or sculptors.

The BBC's arts editor Will Gompertz told BBC News Channel presenter Simon McCoy why non-traditional forms of art had been selected in the shortlist for the award.
