They did, and it appears that a coverup was underway[1][2]. I need to note that I am not asserting who was pushing to cover up Horizon's issues, that's a matter for the courts and the Inquiry. > Mr Jenkins, Fujitsu's former chief IT architect, is currently being investigated by the Metropolitan Police for potential perjury, the BBC understands. > Mr Jenkins' report and an accompanying memo provide the clearest evidence yet that as early as autumn 2010 the Post Office and Fujitsu, which built the Horizon IT system, were aware of details about the software which could cast doubt on prosecutions, and were keeping them hidden. > The memo, which summarised a series of meetings about the report, said that if the bug was widely known, it could cause a "loss of confidence in the Horizon system", provide branches with "ammunition to blame Horizon for future discrepancies" and have "potential impact upon ongoing legal cases". > Mr Jenkins' testimony was also later used in the prosecution of many other sub-postmasters, where details of his report on the bug were again not disclosed.
