Violence between inmates at Winchester Prison has nearly doubled in last five years
Violence between inmates at Winchester prison has nearly doubled in the last five years as attacks reached record levels in prisons across the country.
Figures obtained by Legal Expert have revealed that the number of prisoner-on-prisoner assaults at Winchester Prison has risen, yet assaults on staff have dropped over the past five years.
Winchester Prison had a reported population of 630 inmates in 2024. In 2024/25, the prison recorded 268 prisoner-on-prisoner assaults, up from 152 assaults five years earlier. The number of assaults on staff at the prison has dropped from 225 in 2023/24 to 151 in 2024/25, which is a 33% decrease.
In June 2025, government research highlighted a worrying link between overcrowded conditions and increased violence in prisons, as offenders are nearly twenty per cent more likely to be involved in assaults in overpopulated jails.
Consequently, the government announced a £40 million investment in new security measures aimed at reducing violence behind bars.
Patrick Mallon, a solicitor at legal firm JF Law, said: "The alarming year-on-year rise in assaults in UK prisons is a stark reflection of a system under immense strain.
“With prison populations growing and a significant number of prisons now officially overcrowded, the Ministry of Justice is facing a growing crisis as this limited space creates an unstable environment where violence becomes increasingly common.”
The increased rate of violence in prisons is usually put down to factors include overcrowding, lack of purposeful activity, staffing levels, security and poor mental health.
A Ministry of Justice spokesperson said: "This government inherited a prison system in crisis, overcrowded and rife with violence, and we are fixing this by delivering the fastest prison-building programme in more than a century.”
The government’s ‘Plan for Change’ aims to build 14,000 extra prison places by 2031, and the new investment will help combat the flow of contraband, which creates unsafe environments in jails.
