The UK should "make more use of open prisons" to avoid overcrowding and reduce reoffending, the man leading the government's sentencing review has suggested.
David Gauke told the Times that "we have run out of space" in prisons and there is "an opportunity" for the system to change if inmates are given more freedom to leave prison to study and work during the day.
The former Conservative justice secretary has been called in by the government to review sentencing and tackle overcrowding.
His comments follow visits to three prisons in Spain, where reforms have seen 25% of inmates placed in open prisons.
