The Turner Prize is as synonymous with Tate Britain as it is with soiled beds, formaldehyde sharks and media sneering. From 2011, however, the annual show will alternate between the Millbank gallery and venues outside London, beginning with the Baltic Centre in Gateshead. The Prize rewards British visual artists under the age of 50, as judged by a panel of arts grandees. It has only left Tate Britain once before, to the gallery's sister site in Liverpool in 2007, ahead of that city becoming European Capital of Culture. This year's show begins on 5 October at Tate Britain, with the winner declared in December. Image by M@.
