The Post Office Scandal is one of the biggest miscarriages of justice in British history, yet for years it unfolded quietly behind the counter of ordinary village post offices. Hundreds of sub-postmasters were accused of theft, fraud and false accounting after a faulty computer system made it look like money was missing.

Lives were ruined, reputations destroyed, and some victims were even sent to prison. Now, after decades of campaigning and a landmark ITV drama that reignited public outrage, the scandal is finally getting the attention it deserves.

But how did the Post Office get away with it for so long? Who was really responsible for the catastrophic failures of the Horizon system? And why did it take so many years for the truth to come out?
