Post Office had deal with Fujitsu to fix Horizon errors 19 years ago
Published: 12/22/2025

A recent document reveals that the Post Office and Fujitsu had a deal 19 years ago to address transaction errors in sub-postmasters' accounts caused by bugs in the Horizon IT system. This agreement involved Fujitsu correcting errors in the software or compensating the Post Office up to £150 per transaction. The revelation contradicts the Post Office's earlier claims during criminal prosecutions, leading to wrongful convictions and financial ruin for hundreds of sub-postmasters, sparking a public inquiry into the scandal.
