"Some claim crime fell because of the rise in the numbers imprisoned. But the relationship between crime rates and prison population is more complex than that. And it fails to take into account that most of those in prison today will be released 10 years from now. People want to be assured that on release there won't be a drift back into a life of crime.
A duty to the public must be to stop prisoners reoffending through successful rehabilitation. Although we reduced reoffending rates, they are still at almost 70%, so there's still a lot more to do."
What's unclear is whether this will help or hinder Clarke. Sure, Khan's words may reflect a growing consensus around the idea that prison needs to be rethought. But, then, given the dissatisfaction with Clarke on his party's right, an endorsement from Labour's shadow justice secretary – however muted – might be the sort of backup he could have lived without. Perhaps Team Ed isn't being that generous, after all.
