The Home Secretary described Coldingley Industrial Prison as 'a leap into the future' when he opened this £1,600,000 prison in the middle of the Surrey stockbroker belt, recently. To some of the men inside, familiar with grim, overcrowded, old-fashioned prisons, and even to some of the staff, it may seem just like a step in the right direction rather than a radical leap forward. But it is a change, and a dramatic one. Even though it only holds 300 men, one per cent of the prison population, it may at least point the way ahead in prison treatment. Do we lock men up as punishment, or should we rehabilitate them as citizens? And is Coldingley the answer? What more should be done?
