At least 70 people within the Post Office and Royal Mail knew of errors with the Horizon IT system, according to its manufacturer.
Hundreds of sub-postmasters were wrongly prosecuted on the basis of accounting errors produced by the Horizon system.
The barrister for Horizon manufacturer Fujitsu told the inquiry into IT and Post Office failures it had identified a list of people who knew of bugs, errors and defects within the computer program.
These individuals were senior in the organisation, including Post Office board members, senior executives, in-house lawyers, and staff in the security and investigations teams, said counsel for Fujitsu Richard Whittam.
The inquiry received “unequivocal evidence” of these individuals’ knowledge of the Horizon flaws, he added.
It was these flaws that generated imagined financial shortfalls in Post Office branches which were used by the organisation to bring private prosecutions against more than 700 people for theft and false accounting between 1999 and 2015.
Others were bankrupted, lost homes, were isolated from and left communities, suffered ill health and relationship breakdown, and some died by suicide as a result of having to pay back money they never owed.
In concluding Fujitsu’s evidence to the inquiry, Mr Whittam said the Post Office knew of the flaws 25 years ago, and it was not fundamentally the fault of Horizon but of corporate wrongdoing.
“Evidence has demonstrated that these miscarriages of justice were not caused by technological failures exclusively or even primarily but are instead, the product of serious human and organisational failures in conduct, ethics, governance and culture,” he said.
Tuesday is the final day of submissions at the Post Office Horizon IT Inquiry, which has run for two and a half years.
Core participants such as victims, the Post Office, government departments and Fujitsu have been giving their closing submissions.

Post Office Capture victims to be offered redress
People distancing for ‘self-preservation’
The legal representative for Paula Vennells who was at the helm of the Post Office during its prosecution of sub-postmasters said she was “entitled to rely” on what she believed was competent legal counsel and IT experts to provide accurate information to her, the board and executive team.
“It is inevitable, having regard to the very human desire for self-preservation, that witnesses will now seek to distance themselves from Ms Vennells,” her barrister said.
In bringing its evidence to a close the Post Office on Tuesday told the inquiry it “must end this closing statement as it began, with an apology”.
It reiterated its “determination to continue with the process of learning the lessons from this inquiry”.
It added: “The Post Office remains firmly committed to ensuring that nothing like this could ever happen again but acknowledges that it will rightly be judged in the months and years to come by what it does, not by what it says it is going to do.”
As a ban on the sale of disposable vapes comes into force on Sunday, a doctor who set up the first-ever clinic to help children stop vaping has said she has seen patients so addicted they couldn’t sleep through the night without them.
Professor Rachel Isba established the clinic at Alder Hey Hospital in Liverpool in January and has now seen several patients as young as 11 years old who are nicotine dependent.
“Some of the young people vape before they get out of bed. They are sleeping with them under their pillow,” she told Sky News.

“I’m hearing stories of some children waking up at three o’clock in the morning, thinking they can’t sleep, thinking the vape will help them get back to sleep. Whereas, actually, that’s the complete opposite of how nicotine works.”
Ms Isba said most of her patients use disposable vapes, and while some young people may use the chance to give up, others will simply move to refillable devices after the ban.
“To me, vaping feels quite a lot like the beginning of smoking. I’m not surprised, but disappointed on behalf of the children that history has repeated itself.”
A government ban on single-use vapes comes into effect from Sunday, prohibiting the sale of disposable vaping products across the UK, both online and in-store, whether or not they contain nicotine.

The Department for Environment, Food and Rural Affairs (Defra) said usage among young vapers remained too high, and the ban would “put an end to their alarming rise in school playgrounds and the avalanche of rubbish flooding the nation’s streets”.

Circular economy minister Mary Creagh said: “For too long, single-use vapes have blighted our streets as litter and hooked our children on nicotine. That ends today. The government calls time on these nasty devices.”
At nearby Shrewsbury House Youth Club in Everton, a group of 11 and 12-year-old girls said vape addiction is already rife among their friends.
Yasmin Dumbell said: “Every day we go out, and at least someone has a vape. I know people who started in year five. It’s constantly in their hand.”

Her friend Una Quayle said metal detectors were installed at her school to try to stop pupils bringing in vapes, and they are having special assemblies about the dangers of the devices.
But, she said, students “find ways to get around the scanners though – they hide them in their shorts and go to the bathroom and do it”.

The girls said the ban on disposables is unlikely to make a difference for their friends who are already addicted.
According to Una, they’ll “find a way to get nicotine into their system”.
As well as trying to address the rise in young people vaping, the government hopes banning single-use vapes will reduce some of the environmental impact the devices have.
Although all vapes can be recycled, only a tiny proportion are – with around eight million a week ending up in the bin or on the floor.
Pulled apart by hand
Even those that are recycled have to be pulled apart by hand, as there is currently no way to automate the process.
Scott Butler, executive director of Material Focus, a recycling non-profit group, said vapes were “some of the most environmentally wasteful, damaging, dangerous consumer products ever sold”.
His organisation worries that with new, legal models being designed to almost exactly mimic disposables in look and feel – and being sold for a similar price – people will just keep throwing them away.
He said the behaviour “is too ingrained. The general public have been told ‘vapes are disposable’. They’ve even been marketed this way. But they never were disposable”.
A ban on disposable vapes comes into force on Sunday, with a warning issued about the “life-threatening dangers” of stockpiling.
From Sunday it will be illegal for any business to sell or supply, or have in their possession for sale, all single-use or disposable vapes.
Online nicotine retailer Haypp said 82% of the 369 customers they surveyed plan to bulk purchase the vapes before they are no longer available.
But the vapes contain lithium batteries and could catch fire if not stored correctly.

While more than a third (34%) of people surveyed by Haypp said they would consider buying an illegal vape after the ban, the overall number of people using disposable products has fallen from 30% to to 24% of vapers, according to Action on Smoking and Health.
Shops selling vapes are required to offer a “take back” service, where they accept vapes and vape parts that customers return for recycling – including single use products.
The Local Government Association (LGA) led the call for a ban two years ago, due to environmental and wellbeing concerns, and is warning people not to stockpile.
Cllr David Fothergill, chairman of the LGA’s Community Wellbeing Board, said: “Failing to store disposable vapes correctly could cost lives, given the significant fire risk they pose.”
How disposable vapes catch fire – or even explode
Figures obtained by the Electric Tobacconist, via Freedom of Information requests, found an increase in vape related fires – from 89 in 2020 to 399 in 2024.
Many disposable vapes use cheap, or even unregulated lithium-ion batteries, to keep the costs down. These batteries often lack proper safety features, like thermal cut offs, making them more prone to overheating and catching fire.
If the battery is damaged, or overheats in any way it can cause thermal runaway – a chain reaction where the battery’s temperature rapidly increases, causing it to overheat uncontrollably.

Then, once these fires start start, they are very hard to stop. Water alone can make things worse if the battery is still generating heat, so they require specialised fire suppressants to put them out.
Batteries can then re-ignite hours, or even days later, making them a persistent hazard.
Disposable vapes are a hazard for waste and litter collection and cause fires in bin lorries, even though customers have been warned not to throw them away in household waste. They are almost impossible to recycle because they are designed as one unit so the batteries cannot be separated from plastic.

Some 8.2 million units were thrown away, or recycled incorrectly, every week prior to the ban.
The Department for Environment, Food and Rural Affairs (Defra) said usage among young vapers remained too high, and the ban would “put an end to their alarming rise in school playgrounds and the avalanche of rubbish flooding the nation’s streets”.
Circular economy minister Mary Creagh said: “For too long, single-use vapes have blighted our streets as litter and hooked our children on nicotine. That ends today.

‘One in five say they will return to cigarettes’
Separate research by life insurance experts at Confused.com found two in five people (37%) planned to stop vaping when the ban starts.
Nearly one in five (19%) said they would return to cigarettes once the ban comes into force.
The research was based on the answers of 500 UK adults who currently vape.
Vaping and smoking also appears to be on the rise, with Confused.com saying there was a 44% increase in the number of people declaring they smoke or vape on their life insurance policy since 2019.
Russell Brand has pleaded not guilty to rape and sexual assault charges as he appeared in court in London.
The British comedian and actor, from Hambleden in Buckinghamshire, was charged by post last month with one count each of rape, indecent assault and oral rape as well as two counts of sexual assault.
The charges relate to alleged incidents involving four separate women between 1999 and 2005.
The 49-year-old, who has been living in the US, was flanked by two officers as he pleaded not guilty to all the charges at Southwark Crown Court today.

Brand stood completely still and looked straight ahead as he delivered his pleas.
The comedian, who has consistently denied having non-consensual sex since allegations were first aired two years ago, is due to stand trial in June 2026.
