A Fujitsu executive will give evidence at the Post Office inquiry amid intense scrutiny over the firm’s role in the Horizon scandal.

Paul Patterson, European director of Fujitsu, is set to appear on Friday. Mr Patterson is the latest Fujitsu employee to give evidence to the inquiry. 

On Thursday Peter Sewell, a former operations team manager, and Donna Munro, a former security operations manager, appeared.

The inquiry heard a Fujitsu manager told a colleague tasked with presenting evidence in Post Office prosecutions that a sub-postmaster was a “nasty chap” intent on going “all out” to damage the company’s reputation.

Fujitsu has confirmed it will contribute to compensation payments to Post Office sub-postmasters wrongfully convicted in the Horizon IT scandal.
