Prison arts charity Koestler Arts is back at the Southbank Centre with its annual UK exhibition featuring work created by people in the criminal justice system, including prisoners, immigration detainees, and secure mental health patients. This year’s exhibition, titled No Comment, is being co-curated by Turner Prize-winning artist Jeremy Deller and former prisoner-turned-artist John Costi, with the pair also invited Abbas Zahedi, Andrea Emelife, Jonny Banger , Larry Achiampong, Dr Nicholas Cullinan OBE and Zakia Sewell to help make the selections. The show is giving people in secure settings the opportunity to share their voice, so you can expect pieces that touch on a variety of topics and themes.
