Fujitsu Faces Intense Scrutiny from UK Parliament Over Horizon Scandal Role

Fujitsu Executives Questioned on Horizon Scandal

Fujitsu, the Japanese technology giant behind the faulty Horizon accounting software, recently faced a high-level evidence session in the UK Parliament. On January 6, 2026, Paul Patterson, Fujitsu's Europe CEO, appeared before the Commons Business and Trade Committee to address the company's role in the devastating Post Office scandal, widely recognized as the 'largest miscarriage of justice in UK history'.

During the session, Patterson reiterated Fujitsu's 'moral obligation' to contribute to the compensation of sub-postmasters who were wrongly prosecuted due to the flawed software. However, he stated that the exact figure 'has yet to be decided' and that Fujitsu has not made a provision for it in its financial accounts, pending the completion of Sir Wyn Williams' inquiry report. The government has estimated the total compensation bill to taxpayers at £1.8 billion.

Admission of Software Flaws and Edited Statements

Patterson admitted that 'bugs and errors' had been present in the Horizon system for 'nearly two decades', with Fujitsu staff aware of these issues since 1999. He confirmed that the 'vast majority' of these defects were shared with the Post Office contemporaneously. He also described the editing of witness statements, used to defend the Horizon IT system in prosecutions, as 'shameful', expressing 'surprise' that details of these bugs, errors, and defects (BEDs) were omitted.

Furthermore, Fujitsu acknowledged that remote access to the Horizon system was documented and that the Post Office was aware of this capability. Patterson also voiced a 'deep mistrust' of the Post Office's approach to investigating financial shortfalls, suggesting an over-reliance on Horizon data without considering other potential causes.

Continued Government Contracts Under Fire

The committee's questioning also focused on Fujitsu's continued receipt of substantial government contracts despite its central role in the scandal. Reports indicate that Fujitsu has secured almost £4 billion from approximately 200 public sector contracts over the past decade, including £500 million in extensions since May 2024.

Liam Byrne, the Labour MP and chair of the committee, accused Fujitsu of 'behaving like a parasite on the British state' for continuing to profit while delaying a firm commitment to compensation. Patterson countered this accusation, asserting that Fujitsu is 'not a parasite' and has not bid for new government business since January 2023, with existing contracts being extended at the government's discretion to ensure the continuation of public services.

Broader Context of the Scandal

The Post Office Horizon scandal saw more than 900 sub-postmasters wrongfully prosecuted between 1999 and 2015 based on faulty data from the Fujitsu Horizon software. The scandal gained renewed public attention following an ITV drama in January 2024, prompting Prime Minister Rishi Sunak to announce legislation for the mass exoneration of victims. The ongoing statutory public inquiry, chaired by Sir Wyn Williams, continues to investigate the failings that led to this profound miscarriage of justice.
