This scandal wrongly led to the prosecution of over 700 sub-postmasters between 1999 and 2015, with some facing imprisonment and financial ruin. A petition with over a million signatures demanded Vennells be stripped of her honor.

Government plans to address the situation include possibly enacting a new law to exonerate those wrongfully convicted. A public inquiry into the scandal resumed in January 2023, with technology creator Fujitsu scheduled to face MP questions.

Vennells, who led the Post Office from 2012 to 2019 and was honored in 2019 despite legal action against the Post Office, has apologized for the harm caused.

Questions have been raised regarding her acknowledgment of issues with the Horizon system during her tenure. Stripping of honors officially rests with King Charles, and until the Forfeiture Committee advises, Vennells retains her CBE.

The CWU criticizes Vennells' return of the honor as insufficient, urging her to repay performance bonuses. Victims continue to seek overturned convictions and compensation. Downing Street agrees with Vennells' decision, and support grows for recognition of those who exposed the scandal.

The Post Office, once part of Royal Mail, became separate in 2012. Discussions are underway on quickening justice for affected sub-postmasters, with some officials advocating a "simple bill" to quash convictions, though others, like former attorney general Dominic Grieve, call for case-by-case consideration through the CCRC.

Despite the scandal being labeled as the most significant miscarriage of justice in UK history, only 93 out of hundreds of convictions have been overturned, and the fight for justice continues for many.
