MPs find Treasury-affiliated bodies have engaged Horizon firm since damning 2019 high court judgment

The Japanese technology company Fujitsu, whose flawed technology for the Post Office led to the wrongful prosecution of hundreds of subpostmasters, is confirmed to have held contracts worth more than £3.4bn linked to the Treasury since 2019.

Figures published by the Commons’ treasury committee show £1.4bn of contracts were awarded to Treasury-affiliated organisations after a high court ruling in December 2019 over the company’s software. The judgment found that “bugs, errors and defects” in Fujitsu’s Horizon system could cause shortfalls in Post Office branch accounts.
