Confusion at the gates Why system can't keep track of inmates

The mistaken release of a second foreign prisoner has forced ministers to once again revaluate their security and release procedures, and will once again shine a spotlight on the well-documented problems at HMP Wandsworth.

Much of the emphasis of their concerns is on poor technology and poor communication between prisons, the ministry of justice and the courts which between them are responsible for overseeing the movement of England and Wales's 87,000 inmates.

During the government's emergency prison release scheme in September 2024 to tackle overcrowding, 37 inmates were freed in error because their offences were wrongly logged under repealed legislation.

A computer system designed to automate the calculation of release dates has failed to function as planned, forcing prison staff to work out complex release calculations using calculators.

With increasing numbers of prisoners being held on remand - nearly 20% of the total prison population - demand for their transportation between prison and courts for hearings has grown.

Complaints from staff that warrants are being lost and misplaced as prisoners are being moved between jails have grown louder. Without a warrant, prisoners are allowed to walk free.
