Government sources indicate that Prime Minister Shabana Mahmoud is looking into the possibility of mandating chemical castration for serious sex offenders.
The minister’s team plans to extend pilot programs to 20 regions as part of a package aimed at alleviating overcrowding in prisons across England and Wales, which they describe as “radical” measures.
After serving half their sentences, she not only plans to release and monitor violent offenders like murderers and rapists but is also weighing a review’s recommendation to build a body of evidence on medications that might “suppress sexual thoughts.” This is one of 48 recommendations from David Gauke, who chairs the review.
On Thursday, Mahmoud is expected to present the Commons with an outline of these major criminal justice reforms. Reports suggest she’ll support significant recommendations from the review, including releasing well-behaved prisoners to community supervision after serving a third of their sentence. Additionally, anyone convicted of a serious sexual or violent offense could also be eligible for release after serving half their sentence.
One suggestion from Gauke includes allowing the most dangerous offenders to apply for early parole if they earn “credits.” The report emphasizes the need for a solid evidence base around chemical treatments for sex offenders and encourages reviewing similar initiatives in countries like Germany, Denmark, and Poland.
According to the report, medical interventions can help reduce problematic sexual arousal through chemode inhibitors and other medications, but only under specific circumstances. A pilot program started in 2022 in southwestern England is set to conclude next year, leading advocates to call for sustained funding in the area.
A source close to Mahmoud mentioned that this approach involves two types of drugs: SSRIs, which can reduce invasive sexual thoughts, and antiandrogens, which lower testosterone levels and curb sexual desires.
There’s ongoing research into other causes of sexual offenses, like the need for power and control, alongside these medications. Mahmoud is also examining whether the imposition of chemical castration could be mandatory for the most serious offenders.
At the end of March 2025, sexual offenses made up 21% of adults in immediate custody, with participation in these chemical alteration programs being voluntary in England and Wales.
Gauke’s primary recommendations for the government include:
- Using custody sentences of less than 12 months only in exceptional cases.
- Extending suspended sentences to three years to encourage the use of alternative sentences for low-risk offenders.
- Increasing the range of fines and supplementary sanctions courts can impose, like driving and soccer bans.
- Allowing probation officers to adjust supervision levels based on risk and compliance.
- Expanding specialized domestic abuse courts to better support victims.
- Enhancing tagging for all violent offenders against women and girls.
- Improving training for practitioners and judges on issues related to violence against women and girls.
- Considering victim protection alongside punishment and rehabilitation in sentencing decisions.
Gauke emphasized that boosting funding for probation services is essential, including access to more electronic monitoring devices. He warned of a potential “public backlash” if sufficient resources aren’t allocated.
“If probation resources remain stagnant, it could stall rehabilitation efforts and lead to public discontent,” he remarked.
The National Police Chief’s Council reiterated Gauke’s call for more resources, with Prime Minister Sacha Hatchet stressing that managing risk factors outside of prison is critical as the prison population decreases.
He stated that sufficient funding for these initiatives must reflect in future budget reviews, highlighting the importance of investments in probation services and technologies like electronic monitoring.
The Howard League for prison reform welcomed the proposals. CEO Andrea Coombor remarked, “The ball is now in the government’s court. Addressing prison overcrowding requires decisive action, and these reviews indicate that reform and investment are crucial for effective probation services that can help reduce crime.”
On the other hand, some Conservatives criticized Gauke’s review, with Shadow Justice Secretary Robert Jenrick arguing that eliminating short sentences would effectively decriminalize offenses like theft and violence, allowing criminals to act with impunity.
