Post Office scandal: Fujitsu staff knew about bugs, errors and defects in the system for years

The European boss of Fujitsu has admitted the company “clearly let society down” as he apologised again to subpostmasters and postmistresses over its role in the Horizon scandal.

Giving evidence to the public inquiry, Paul Patterson said Fujitsu staff had known about bugs, errors and defects in the system for years – but claimed the firm only became aware “latterly” that faulty data was being used in prosecutions.
