The Government is taking unprecedented action to improve safety in prisons. We have recruited over 4,700 more prison officers since October 2016 and we now have the greatest number in post since early 2012. The Challenge, Support and Intervention Plan case management process for prisoners at risk of violence has been mandated for all prisons to help staff to manage violent prisoners and those identified as posing a raised risk of being violent.

We have announced an extra £100 million for security, on top of £70 million we were already spending to make prisons safer, more secure and decent. This is part of the Government’s new £2.75bn investment to modernise and maintain our prisons, create 10,000 additional places, and step up security to stop the flow of drugs and mobile phones. We are equipping officers with PAVA incapacitant spray and body-worn cameras to help prevent serious harm to staff and prisoners when dealing with violent incidents. We are improving perimeter security and introducing new x-ray scanners, drug detection dogs and dedicated search teams, to address the supply of drugs that we know are fuelling much of the violence in custody.
