The man in charge of a review of the prisons crisis says building more jails is not the answer and a more "strategic" approach is needed to free up space.
The former Conservative Justice Secretary David Gauke has been called in by Labour to review sentencing, following the early release of nearly 3,000 offenders in recent weeks.
The sentencing review was a Labour manifesto pledge and the party has also appointed Lord Timpson, former head of the key-cutting chain that hires ex-offenders and chief of the Prison Reform Trust, as its prisons minister.
Gauke, who was justice secretary under Theresa May, has previously suggested that jail terms of less than six months should be scrapped.
