On the 1st April 2020 the CCJS hosts a major event on imprisonment in Britain. This will be exactly 30 years since the first day of the Strangeways protests. Lasting 25 days and spreading across several prisons, Strangeways remains the largest prison protest in England and Wales. Thirty years on, the dysfunctions and problems of the prison system that gave rise to the protests remain as pressing as ever. This is a significant moment to bring together activists, academics, organisations and concerned communities who have been involved in political struggles about the use of imprisonment in the last 30 years.
