Albert Woodfox was one of the ‘Angola Three’, the three African-American former prison inmates who were held for decades in solitary confinement.

Woodfox has recently published his book 'Solitary', retelling the story of the 44 years and 10 months he spent inside for a crime he didn't commit.

He speaks to Krish about how he stayed sane whilst imprisoned and how he is still fighting against ‘the system'.
