During the Post Office scandal inquiry, it was revealed that former CEO Paula Vennells preferred not to use the term ‘bugs’ when referring to the faulty Horizon IT system. Instead, she opted for the term ‘exceptions.’ This preference was disclosed by the Post Office’s former lead internal lawyer, who also expressed her belief that her superiors expected her to manipulate a review of Horizon by forensic investigators. The inquiry provided a platform for a wrongly-jailed subpostmaster to witness the proceedings.
