Founding member of Pussy Riot and one of the most high-profile political activists in Russia imprisoned by Vladimir Putin's government - in this Ways to Change the World Podcast, Krishnan Guru-Murthy speaks to Masha Alyokhina.

She became internationally known after the group's protest performance in Moscow's Cathedral of Christ the Saviour in 2012, which led to her arrest and two years in prison. Since her release, Masha has continued to challenge Putin's regime and fight for freedom of expression through her art, writing and activism. And her new book, Political Girl, is an account of protest, prison and her thoughts about Russia today.
