I know that my hon. Friend takes a keen interest in this matter, and I will examine his proposal. We have already overhauled the process for allowing prisoners out on temporary licence, which has led to a 39% drop in the number breaching their licence conditions. The rate of prisoners escaping from prison has reached a record low. As I understand it, prisoners with a history of escaping or absconding while on temporary release are prevented from transferring to open conditions other than in the most exceptional cases. I will look at those exceptional cases to see whether there is a case for the blanket ban that my hon. Friend has talked about, and I will write to him over the summer.
