Former Post Office CEO Paula Vennells refuses to comment on allegations of lying to MPs about the Horizon IT scandal.

Former Post Office CEO Paula Vennells, confronted by Channel 4 News, refused to comment on allegations she lied to MPs and if there was a cover-up over the Horizon IT scandal. Vennells earned £5.1m during her tenure while the flawed Horizon system caused hardship for ex-subpostmasters. She faces questions after a secret recording suggested she knew the software could be remotely accessed, contradicting her parliamentary testimony.
