This case received new public attention this year when ITV broadcast a drama series, "Mr Bates vs The Post Office," about the sub-postmasters fight for justice.
Horizon was manufactured by Fujitsu in 1999 and rolled out across Post Office branches to manage financial transactions.
"We did have bugs and errors in the system and we did help the Post Office in their prosecutions of the sub-postmasters," he told the committee.
The government has set aside 1 billion pounds in compensation for victims of the Post Office scandal.
And the role of the post office has been well known in these court prosecutions, but Fujitsu for some reason had been rarely mentioned in the press."
