The hon. Gentleman raises an interesting question. Connected to the question of crowding in prisons is the question of how many people are sentenced. The two are clearly related. The Scottish Government have led on the question that the hon. Gentleman now raises: what is the point of sending someone to prison with a three-month sentence? What does that achieve? In effect, it means that somebody is in prison for less than six weeks. Is that really a length of time that allows them to take any kind of punishment and that will deter anybody? Above all, is it enough time to rehabilitate someone—to really turn their life around so that they do not reoffend? The evidence suggests that very short sentences are in fact likely to lead to more reoffending than a community sentence. It is an issue that we need to look at very carefully.
