The Capture Software Scandal: Another Chapter in the Post Office’s IT Failures

Uncovering a Predecessor to Horizon’s Failures

The Post Office scandal, which has already devastated hundreds of lives through the faulty Horizon IT system, may be even more extensive than initially believed. A powerful committee of Members of Parliament has now urged the government to overturn convictions that were secured using data from Capture, an accounting software system that predated Horizon. The Business and Trade Committee (BTC) has released a damning report calling for “urgent” legislation to quash these earlier convictions and thoroughly investigate the full scope of this potential miscarriage of justice. The Capture system was used in approximately 2,500 Post Office branches throughout the 1990s, just before the notorious Horizon system replaced it in 1999. Like its successor, Capture appears to have generated false accounting shortfalls that led to innocent sub-postmasters being wrongfully accused of theft and fraud. This revelation suggests that the injustice inflicted on Post Office workers may stretch back even further than the widely publicized Horizon cases, potentially adding decades to a scandal that has already been described as one of Britain’s worst miscarriages of justice.

The parallels between Capture and Horizon are disturbing and all too familiar. Both systems generated incorrect financial data showing supposed shortfalls in Post Office branch accounts. Based on these flawed figures, countless sub-postmasters found themselves accused of stealing money that had never actually gone missing. Many were prosecuted and convicted, their reputations destroyed and their lives thrown into chaos. Others, desperate to avoid prosecution, went into crippling debt attempting to cover the phantom losses that the faulty software had created. Families lost their homes, their businesses, and their peace of mind. Many suffered serious physical and mental health problems as a direct result of the stress and trauma. A government-commissioned report released in 2024 confirmed what many had long suspected: that Capture was indeed responsible for generating accounting errors. Following this finding, the government opened a state compensation scheme for Capture victims who had not been convicted, but the situation for those who were prosecuted remains in limbo, hence the urgent call from the committee for convictions to be overturned.

The Tip of Another Iceberg

The true scale of the Capture scandal remains unknown, and this uncertainty is perhaps one of its most troubling aspects. Sky News investigation uncovered a legal report revealing that the Post Office had been aware of Capture’s serious flaws since as early as 1992—yet continued to use the system and prosecute people based on its unreliable data. This raises profound questions about institutional accountability and whether the Post Office knowingly ruined lives while aware that its evidence was fundamentally flawed. Currently, a legal challenge is making its way through the Court of Appeal, attempting to overturn at least one conviction obtained during the Capture era. The outcome of this case could have significant implications for other potential victims. However, incomplete record-keeping from that period means that establishing exactly how many people were affected is extremely difficult. The BTC’s report grimly noted that the currently confirmed number of Capture cases may represent merely “the tip of another iceberg”—a chilling echo of how the Horizon scandal itself gradually revealed its true magnitude over many years. If this assessment proves accurate, hundreds or even thousands more innocent people may have been wrongly convicted, with some potentially having served prison sentences based on nothing more than faulty software.

Fujitsu’s “Unacceptable Failure” to Contribute

While victims continue to suffer, Fujitsu—the Japanese multinational corporation that created the Horizon system—has come under withering criticism from the committee for its failure to contribute financially to the redress schemes. Despite publicly acknowledging a “moral obligation” to help compensate victims, Fujitsu has so far paid exactly nothing toward the cost of putting things right. Even more remarkably, the company hasn’t even agreed to pay any specific amount, let alone made an actual payment. Committee chair Liam Byrne described this failure to even offer an interim payment as “unacceptable,” particularly given that the total cost of redress payments has now reached approximately £2 billion. This massive bill is being footed almost entirely by British taxpayers, since the Post Office is a completely state-owned company. Meanwhile, Fujitsu continues to profit handsomely from “substantial” government contracts, despite claiming to have imposed a self-imposed moratorium on bidding for new public sector work. The report highlighted this continued financial relationship with government as deeply problematic and fundamentally unfair to taxpayers.

“It is simply wrong that taxpayers are covering the costs for Fujitsu’s sins while Fujitsu is still profiting from taxpayers’ funded contracts,” Mr. Byrne stated bluntly. The situation creates a perverse scenario where British citizens are effectively paying twice—once through their taxes to compensate Fujitsu’s victims, and again through government contracts that continue to enrich the company responsible for creating the faulty system in the first place. To address this unjust situation, the committee has called on the government to demand an urgent interim payment from Fujitsu and to publish full details of all current government contracts and contract extensions with the company. This transparency would allow the public to understand exactly how much Fujitsu continues to benefit financially from relationships with UK government bodies, even as it refuses to contribute to cleaning up the catastrophic mess its technology created.

Persistent Problems in the Compensation Process

Beyond the question of who pays for compensation, serious problems persist in how that compensation is actually being delivered to victims. The BTC’s review of the three separate schemes established for Horizon victims found what chair Liam Byrne described as “serious structural failings still blocking the road to justice.” One scheme, designed for people who were financially harmed by having to cover Horizon’s wrongly generated shortfalls, has proven particularly problematic. Administered by the Post Office itself—an arrangement many find questionable given the organization’s role in the scandal—this scheme routinely makes initial compensation offers that are later overturned and significantly increased on appeal to the Department for Business and Trade. These “stark disparities” between what the Post Office initially offers and what victims eventually receive after appealing suggests the scheme is fundamentally broken and no longer fit for purpose. Victims who have already suffered years of injustice are being forced to fight yet again, this time for fair compensation, extending their ordeal even further.

Processing times remain far beyond target timelines for fully assessed claims, and thousands of late claims are still waiting for a final offer. A separate compensation scheme specifically for those who were wrongfully convicted based on Horizon data is performing somewhat better, according to the report, but even here claimants face unnecessary obstacles. The committee noted that people are still being forced to navigate frustrating administrative hoops when seeking compensation. The report recommended that the effective guaranteed minimum payment of £600,000 should simply be paid in full to all eligible claimants without further delay or bureaucratic barriers. That said, some progress has been made overall in delivering redress. More than 11,300 claimants have now received compensation payments totaling £1.44 billion—a significant achievement, though one that has taken far too long and come at enormous emotional cost to those who waited.

Responses and the Road Ahead

In response to the committee’s hard-hitting report, both Fujitsu and the Post Office have issued statements attempting to address the criticisms, though whether these responses will satisfy victims and their advocates remains doubtful. A Fujitsu spokesperson said the company continues to work with the UK government to ensure it adheres to the voluntary restrictions on bidding for new contracts while the Post Office Inquiry remains ongoing, and claimed Fujitsu is “engaged with government regarding Fujitsu’s contribution to compensation.” However, this carefully worded statement notably avoids making any specific commitment about when or how much the company might actually pay. The Post Office, for its part, said it welcomes the committee’s scrutiny and commitment to ensuring full, fair, and timely compensation for those harmed during the Horizon scandal. A spokesperson highlighted that progress has been made, with 87% of eligible Horizon Shortfall Scheme applications having received an offer and £882 million paid through the scheme. The organization stated it is processing applications “as quickly as possible” and will review the committee’s recommendations while continuing to work closely with the Department for Business and Trade.

These responses are likely to be viewed with considerable skepticism by victims and their supporters, who have heard similar reassurances many times before while actual progress remained frustratingly slow. The revelation about Capture adds another troubling dimension to an already appalling scandal, suggesting that the Post Office’s willingness to prosecute innocent people based on unreliable IT systems may have an even longer history than previously known. The committee’s call for urgent legislation to quash Capture-era convictions recognizes that justice delayed is justice denied—many of those wrongly convicted are elderly or in poor health, and some will have already died without seeing their names cleared. As public attention on this scandal remains intense, particularly following the dramatic ITV series that brought the Horizon victims’ stories to a wider audience, the pressure on government, Fujitsu, and the Post Office to act decisively continues to mount. The question now is whether that pressure will finally translate into the swift, comprehensive justice that victims have deserved for so long.
