The IT company whose faulty software is at the centre of the Post Office scandal is reportedly still managing a top-secret UK military system. Defects in Fujitsu's Horizon platform led to more than 900 sub-postmasters being wrongfully prosecuted, after they were blamed for apparent shortfalls in their accounts, which did not actually exist. However, a source told the i newspaper that the Japanese firm has been managing a secretive computer system facilitating the "strategic command and control of UK Armed Forces " for decades. The UK intelligence source also claimed Fujitsu was still overseeing the contract, despite it being reallocated to another firm almost two years ago. The delay in moving Fujitsu away from the project is reportedly because of the deep ties the IT giant has with UK Government departments, the highly sensitive nature of the contract and waits for new staff to receive security clearances.
