The United Kingdom has officially launched an expanded early release scheme under the Sentencing Act 2026 to address severe prison overcrowding in England and Wales. Following warnings from prison governors that capacity levels of 97% to 98% risked a system collapse, the government is implementing a staged release of approximately 5,000 inmates through June 2027.

Under these new rules, certain prisoners may be released after serving only one-third of their sentence, a reduction from previous thresholds of 40% or 50%. To mitigate public safety risks, the government has excluded individuals convicted of serious offenses, such as murder, manslaughter, rape, and specific child sex offenses. The first wave, consisting of approximately 700 prisoners, is scheduled for release on October 1.

Diplomatic friction persists, particularly with Poland. Polish authorities have reiterated concerns regarding the lack of transparency, noting that the UK government has yet to provide specific lists of foreign nationals, including Polish citizens, who are slated for release or deportation. This lack of data continues to hinder international preparations for the return of these individuals.
