The Post Office Inquiry has concluded its witness testimonies, centering on accountability and knowledge regarding the flawed Horizon IT system. Former CEO Paula Vennells faced intense scrutiny but provided few definitive answers about her awareness of issues. Witnesses, including Fujitsu’s Gareth Jenkins, revealed concerning past conduct that raises questions about executive awareness. Politicians, too, expressed regret over their lack of insight into the crisis, attributing it to the rapid turnover of officials. The inquiry is set to conclude next month, with implications for the Post Office’s future procedures and governance looming large.
