The UK offender management capability is based on the principles of holding prisoners securely, reducing the risk of prisoners re-offending and providing safe and well-ordered establishments.
However, there is increasing concern that prisons and offenders are vulnerable to radicalisation. There are around 150 terror related offenders in the UK currently and as the threat of terrorism grows this number is set to increase.
The custody estate in the UK consists of adult prisons, young offenders institutions and secure training centres.
The majority of these are run by the Prison Service but the UK also has significant experience in terms of privately run prisons and detention centres. Community sentencing has been used widely in the UK and offender monitoring systems, managed by private security companies (reporting breaches to police) are well established.
