Veteran war photographer Sir Don McCullin speaks to Today about a life documenting conflicts in the Congo, Afghanistan and Iran, in a career spanning 60 years. From February 5th the Tate Britain will host a retrospective of his career with over 250 photographs. He says: "I wanted to be part of an honourable profession and the lives of journalists sacrificed makes me feel close to that notion." (Image: Sir Don McCullin, credit: PA)
