Timeline of Post Office scandal and when it started
Here’s how one of the UK’s worst miscarriages of justice involving hundreds of innocent sub-postmasters came to light
The Post Office scandal has played out over 25 years and its victims are still fighting for justice. More than 700 branch managers were convicted of false accounting, theft and fraud based on faulty Horizon software developed and maintained by Fujitsu, but fewer than 100 have had their convictions overturned.
Some were wrongfully sent to prison, while many were financially ruined and some have died, in several cases by taking their own lives.
Yahoo News UK takes a detailed look at the timeline of the Post Office scandal.
20 February 2024
The Post Office is being accused of acting illegally, after arguing in court that the Horizon system could not be accessed remotely - despite a 2016 investigation showing that it could be.
The BBC reported that then prime minister David Cameron's government was aware that the Post Office has ditched an investigation into the Horizon software that could have helped to exonerate wrongly accused postmasters.
The 2016 investigation looked through 17 years of Horizon records to find out whether the system could be accessed remotely, with the Post Office informing ministers that a probe was taking place.
Despite it reportedly finding instances in which the software was accessed remotely, the investigation was stopped as the postmasters began legal action, the BBC found.

Messages handed in to the Post Office Horizon inquiry show that cash bonuses were handed out to investigators for each postmaster that was convicted. Gary Thomas, a long-term Post Office employee, claimed the incentive scheme was “part of the business“, and that everyone on the security team was “on a bonus”, thought to be worth thousands. Thomas says the bonuses influenced his work as an investigator.
Thomas was the lead investigator in the case of Julian Wilson, who was wrongly convicted of stealing £27,000 from his Post Office in Astwood Bank, Worcestershire, in 2008. Wilson died of bowel cancer in 2016 and had his conviction quashed after his death.
In an email exchange during the initial investigation, reported in The Telegraph, Wilson told a colleague that he was “pleased” to get documents relating to Wilson’s case. When asked why, he wrote back: “Because I want to prove that there is FFFFiiinnn no ‘Case for the Justice of Thieving Subpostmasters’ and that we were the best Investigators they ever had and they were all crooks!!”

9 January 2024
Paula Vennells, CEO of the Post Office between 2012 and 2019, announces that she will hand back her CBE.
She says: “I have so far maintained my silence as I considered it inappropriate to comment publicly while the inquiry remains ongoing and before I have provided my oral evidence.
“I am, however, aware of the calls from sub-postmasters and others to return my CBE.
“I have listened and I confirm that I return my CBE with immediate effect."
8 January 2024
A petition calling for Vennells to have her CBE rescinded reaches more than one million signatures. Prime minister Rishi Sunak says he would “strongly support” the Honours Forfeiture Committee if it chose to look into revoking her honour.
