Questions remain over how much Fujitsu knew about the software bugs and what it told the Post Office. The company has continued to receive billions of pounds in government contracts since reports of the scandal first emerged. Asked by MPs why the company did not take action earlier, Mr Patterson, who has led its UK division since 2019 and worked for Fujitsu since 2010, said: "I don't know. I really don't know. On a personal level I wish I did know."
