War in Ukraine eclipses Venice Biennale

She's called herself a "caretaker of memory". Zineb Sedira is as much an artist as she is a researcher, historian and filmmaker. The Franco-Algerian artist is representing France at the 59th Venice Biennale of contemporary art in April. She joins us in the studio to talk about the influence of Algerian activist cinema on her work. We also discuss how the war in Ukraine has jeopardised Pavlo Makov's participation in the Biennale, and she weighs in on the decision of Russian artists to boycott their own, state-sponsored pavilion.
