Martin Jones, His Majesty's Chief Inspector of Probation for England and Wales, has told a national broadcaster that releasing thousands of prisoners early risks enabling "a serious sexual or violent offence or even murder" because probation staff are already stretched beyond capacity. The government plans to free around 5,000 offenders from October 2026 under new legislation designed to relieve overcrowded jails. Probation officers are responsible for supervising these offenders once released, checking compliance with conditions such as curfews and drug bans.
Jones said he could not be certain the system would hold up under the added strain.
Ultimately I'm not fully confident that the probation system will be able to cope with this massive work and there's a risk that things will go wrong.
Probation services are already under unprecedented pressure. I mean, they're managing a caseload of 258,000 cases, that's nearly three times the number that are in our prisons, and obviously the early release scheme will be increasing that pressure considerably.
When asked directly what could go wrong if the additional autumn releases proceed, Jones did not soften his warning.
That could be a serious sexual or violent offence or even murder.
The scheme is part of a wider push tied to the Sentencing Act, which has already reshaped release policy. Andy Burnham previously announced a review of the early prisoner release policy in July, citing overcrowding pressures and criticism from the mother of PC Andrew Harper following the release of two of his killers. That review led to changes: according to our earlier coverage, rapists and serious child sex offenders were barred from the scheme, a decision that resulted in about 1,000 fewer prisoners being released early. Despite this, Kemi Badenoch has separately warned that some child sex offenders may still be eligible for early release under the scheme, a claim that sits in tension with the government's stated exclusions.
Why are police chiefs concerned?
On Tuesday, 50 police chiefs from Scotland, England, Wales and Northern Ireland signed a joint letter to the prime minister demanding greater consideration for victims when sentences are altered under schemes such as this one.
Families across the country are now facing the distress of learning that offenders may be released earlier than they understood when sentence was passed.
The chiefs specifically urged Burnham to exhaust "every legal option" to stop the early release of PC Andrew Harper's killers, Jessie Cole and Albert Bowers. Downing Street had initially said it would not be possible to exclude "one or two offenders" convicted of manslaughter from the scheme, but after public outcry Burnham instructed the justice secretary to find a legal route to bar the pair. Burnham has since said he is "confident" they can be excluded, and the police chiefs' letter welcomed his intervention, calling it an opportunity to "examine every lawful avenue in PC Andrew Harper's case, but to ensure similar concerns do not arise again."
How has probation staffing been affected?
Probation officers do far more than monitor curfews; they help former prisoners secure housing, employment and benefits, and assess ongoing risk to the public. Their workload is set to grow substantially as more offenders, including some convicted of violent crimes, are freed months ahead of schedule under the Sentencing Act. Jones said the probation caseload has already risen 8% over the past two years, much of it driven by a separate early release scheme introduced in 2024 when prisons neared full capacity and which has since freed tens of thousands of offenders sooner than planned.
One probation officer described the mood among colleagues ahead of the autumn releases in stark terms.
We can't cope with this - we've been saying that to anybody who will listen. At the minute I think it's pure panic in terms of where we're at. I don't understand how there can be this level of pressure put on us. The worst that can happen is that things are missed, plans aren't put into place and we don't give people the level of service they need and that leads to serious further offences. That leads to death under supervision.
Official figures cited by Jones show the scale of the shortfall: as of March 2026, there were 5,554 full-time equivalent probation officers against a target of 7,110, a gap of 1,556 posts. Inspectorate reports published between January and March 2026 flagged staffing gaps, inexperience among staff, poor information-sharing and the burden of large-scale change programmes on an already overstretched workforce. Speaking separately to a national radio station, Jones underlined the dilemma facing officials, saying there are "no easy solutions or risk-free choices" and warning that "if you stop supervision, there will be some risk that will rise," according to a report by LBC.
Frustration among staff culminated in industrial action. On Tuesday, probation officers voted to strike over the scheme, with the union Napo reporting that 90% of members backed potential action.
This ballot wasn't about members being too busy. It was professionals warning they cannot protect the public properly when there are not enough people to do the work.
The Ministry of Justice said it was "disappointed" by the ballot result. A department spokesperson said protecting the public remains the government's "top priority" and pointed to investment in probation, including exceeding last year's recruitment target with 1,389 trainee probation officers taken on. The spokesperson added that this is "making sure the Probation Service has the resource it needs to keep dangerous offenders under closer surveillance than ever before," and said the Sentencing Act is "restoring order to a prison system left on the brink of collapse, while our record £700m investment in probation and community punishment is ensuring staff have the resources, powers, and technology they need to manage offenders safely in the community."
Burnham has said there will be a presumption that offenders released under the new laws are tagged and subject to longer supervision periods, placing further responsibility on probation staff. Jones was sceptical that tagging alone would ease the burden.
Electronic tagging has been talked about as a key part of the arrangement but actually all that provides you with is information to inform their understanding of what is going on and then to act upon that when necessary, and I'm not sure the systems are there and robust enough to assist the probation officer when they're doing their work.
I've previously said that it would be a good idea to look at the overall workload of probation and consider what are the essential things that they need to be doing, not what's desirable. It's a matter of desirable work that I want the probation service to be doing. But with a probation service that probably has a vacancy rate of 20-25%, what can they realistically do.
On Tuesday, Burnham said he was "increasingly confident" that efforts to expand prison capacity would allow the number of people released early to be reduced.
What happens next?
The picture is complicated by conflicting timelines. According to a report from late July, the early-release policy was paused pending an urgent review, with Burnham saying no prisoners would be freed under it while that review continues. Yet according to a House of Commons Library briefing, the statutory release changes remain scheduled to take effect on 2 September 2026 for newly sentenced offenders, applying immediately to those sentenced after that date and phasing in gradually for existing prisoners depending on sentence length. Separately, the Institute for Government's explainer states the broader scheme is expected to be operational from 1 October 2026, roughly matching the autumn start date referenced by Jones and the Ministry of Justice. It remains unclear how the pause described in the review reporting will interact with these statutory dates, and no single confirmed timeline has been established across all sources.
The legal basis for the changes lies in the Sentencing Act 2026, which, according to the Prison Reform Trust's guidance, removes the requirement for a minimum custodial period before release in certain cases. Concerns about the risks of early release are not new: inspectors had already warned, as reported by the Telegraph in 2024, that earlier overcrowding-driven release schemes risked freeing violent offenders and creating public-safety hazards.
