Mr Bates vs The Post Office is based on real events: Alan Bates and other sub-postmasters challenged the Post Office over accounting shortfalls attributed to its Horizon system. ITV’s four-part drama brings that story to television, but it is a dramatic portrayal, not a substitute for the case record or the public inquiry.
What is Mr Bates vs The Post Office about?
The series follows Alan Bates and other sub-postmasters as they challenge the Post Office over shortfalls attributed to Horizon, a computerised accounting system used by the organisation. ITV’s programme notes place Horizon’s rollout in the early 2000s; that note is useful context, not a complete technical history of the system.
ITV describes the programme as a four-part drama written by Gwyneth Hughes and produced by ITV Studios and Little Gem. Its announced cast includes Toby Jones, Monica Dolan, Julie Hesmondhalgh, Lia Williams, Alex Jennings, Ian Hart, Katherine Kelly, Shaun Dooley, Will Mellor, Clare Calbraith, Lesley Nicol, Amit Shah and Adam James. ITV’s series information sets out the programme’s credits and cast.
Why did the drama draw such attention?
The story joins an institutional dispute to the experiences of people challenging how the Post Office treated accounting shortfalls. The Criminal Cases Review Commission (CCRC) describes the scandal as the most widespread miscarriage of justice it has seen. It also says the January 2024 drama brought the issue to public attention. That is the CCRC’s assessment, not a numerical comparison of cases.
#1 Best Overall
ITV reported that the first episode had 9.2 million viewers. That figure is ITV’s own audience report, published in 2024, rather than an independently stated audience measurement in the material cited here. ITV’s announcement gives the figure and its context.
What is drama, and what should readers verify elsewhere?
A television drama shapes real events into scenes and characters. Its episodes can introduce viewers to the subject, but a programme synopsis or portrayal cannot establish the findings of a court, a case review or an inquiry. For those, use the relevant primary record:
| Source | What it can tell you |
|---|---|
| Criminal Cases Review Commission | The CCRC’s role in Post Office cases and its own assessment of the scandal. Its description of the January 2024 drama is also the body’s account of the programme’s public impact. |
| Public inquiry record | The inquiry’s evidence and proceedings. ITV’s companion-programme description says it uses interviews with key protagonists, drama clips, archive and filmed locations to explore the impact on sub-postmasters; that is not itself an inquiry finding. ITV’s description of the companion programme explains its approach. |
| UK Government announcement, 10 January 2024 | What the Government announced on that date: plans for legislation to quash convictions related to the scandal, and an upfront payment for members of the Group Litigation Order cohort who had not been criminally convicted. It is a dated announcement, not evidence of present-day implementation or an individual’s eligibility. |
For a fuller account of what was established, read the inquiry and case-review material rather than treating the drama as a documentary record.

No. ITV presents Mr Bates vs The Post Office as a four-part drama. ITV separately describes Mr Bates vs The Post Office: The Real Story as a companion programme using interviews, archive material, clips from the drama and filmed locations. The companion programme may add context, while the CCRC, inquiry and government records serve different purposes and should be consulted for their respective findings or announcements.
