The Post Office Horizon scandal continues to unfold as MPs question former Post Office chairman Henry Staunton and CEO Nick Read. Staunton accuses the government of smearing him, while Read acknowledges subpostmasters' trauma. The faulty Horizon IT system led to wrongful convictions, with at least four criminal convictions linked to a second faulty IT system. Post Office CEO Nick Read reveals that over a thousand subpostmasters may have experienced shortfalls due to the Capture software. The government is expected to bring forward legislation to exonerate subpostmasters caught up in the scandal.
