The public inquiry into the Horizon IT scandal, described as the UK’s most widespread miscarriage of justice, captivated many, leading to a phenomenon of ‘superfans’ who closely followed its every development. More than 20 million views were recorded on YouTube, largely due to increased awareness from the ITV drama ‘Mr Bates vs The Post Office.’ Participants shared personal accounts of their emotional journeys through the inquiry, highlighting the significant impact of the scandal on the lives of the sub-postmasters and the broader call for justice.
