Oleksandra Matviichuk is a human rights lawyer, activist and director of the Centre for Civil Liberties in Ukraine, winner of the 2022 Nobel Peace Prize together with the Russian human rights organisation, Memorial, and Belarusian activist Ales Bialiatski. Matviichuk and the Centre have fought for democracy in Ukraine since 2007 and are now part of a ground-breaking international effort to ensure accountability for war crimes. In her acceptance speech for the Nobel Peace Prize, she reminded the world that, “We don’t have to be Ukrainians to support Ukraine. It is enough just to be humans.” She talks to the Guardian’s chief culture writer.
