Stephen Sackur and Liao Yiwu
In a HardTalk interview first broadcast on Thursday 27th March, Stephen Sackur talks to the most censored writer in China, Liao Yiwu.
China is undergoing a period of rapid and profound change, but not everyone stands to gain.
Dissident writer Liao Yiwu seeks to give a voice to the people he calls "the lowest rungs of Chinese society".
He spent four years in jail after writing an epic poem about the Tiananmen Square massacre and his book "The Corpse Walker" is a series of interviews with China's underclass: human traffickers, professional mourners, lepers, migrant labourers.
Even this subject matter is controversial and Liao's every move is shadowed by the authorities.
In a rare interview, Liao talks to Stephen Sackur about his extraordinary life and how he is recording the "voices of the voiceless".
