Watch live as Paula Vennells' final statement is heard in the Post Office Horizon IT Inquiry on Tuesday 17 December.
More than 900 subpostmasters were prosecuted between 1999 and 2015 after faulty Horizon accounting software made it appear money was missing from their accounts.
Hundreds of them are still waiting for compensation – despite the previous Conservative government announcing that those whose convictions were overturned would be eligible for a £600,000 payout.
The investigation began in 2022; Since then, a total of 270,785 documents have been released to key parties and 298 witnesses have testified, said the inquiry's lawyer, Jason Beer KC.
The former postal chief will be among those making their final closing statements on Tuesday.
In written submissions from Ms Vennells' legal team, she continued to deny knowledge of the extent of the errors in the Horizon system which subsequently led to wrongful convictions.
Her lawyers said: “Ms Vennells cannot and will not hide the fact that as CEO she has failed to uncover the truth about the extent of the bugs, errors and deficiencies in Horizon.”
“She simply did not receive the information she should have received from her leadership team, whom she trusted and delegated responsible roles to.”
In its written submissions, the Post Office said: “Some of the evidence was extremely unpleasant to me.” [the Post Office] and the mistakes that were made and the missed opportunities, when viewed through the sharp prism of hindsight, are the ones that [the Post Office] deeply regrets it.”
