On prisons. How does religion play a role in our prison system and can faith stop prisoners reoffending? We speak to Dr Ruth Armstrong from the Institute of Criminology in Cambridge to assess these questions before a hands on discussion with Imam Farooq Mulla and Bob Wilson, both of whom have spent years bringing their faith to the UK's incarceration system. What are the challenges of this job? In what ways can prisoners be redeemed? And does our prison system need urgent help?
