Ver en Cuevana. When Post Office subpostmasters up and down the country started to experience big shortfalls in their accounts, Post Office assumed they were stealing the money and prosecuted them.

For over twenty years, former subpostmaster Alan Bates has fought tirelessly for justice for all the subpostmasters who were so poorly treated by the brand they had loved. This is his story.
