We've asked this week's guest to come up with five pieces of advice for the next government to improve our justice system. Andi Brierley is an author and educator. He was the editor of last year's book, The Good Prison Officer. He spent several years in prison as a young person, serving time for offences fuelled by a drug addiction. Today he teaches at Leeds Trinity University and he trains prison officers through the Unlocked Graduates programme. Find out more about Unlocked Graduates here.
