The BBC's Chris Connell is interviewing me on all matters prisons tomorrow; the Hexham Gaol was built in June 1330, making it the oldest purpose-built prison in England.
We will be discussing my book, Doing Time, the changes we need in todays prisons, the difficulties of getting proper mentoring, the problems of repeat offenders, and the need for radical reform of our approach to prisons - without throwing out the good things that we do. In the evening I am also meeting representatives from the Oswin Project - a local who help give skills and training to former prisoners and help turn them around. A great cause.
