However, one in particular had been championing the plight of the wrongly accused workers for many years, with former Conservative MP (now Lord) James Arbuthnot being a major presence in the dramatisation.

Alex Jennings (This is Going to Hurt) was hired to portray the real-life figure, who is greeted with some scepticism by the mother of subpostmistress Jo Hamilton (Monica Dolan) at the beginning of the series.

However, he soon proves himself to be genuinely dedicated to seeking justice for his constituent Hamilton and her fellow Post Office victims, remaining involved in the case for many years – and continuing to comment to this day.

James Arbuthnot is a Lord who sits on the Conservative benches and was created Baron Arbuthnot of Edrom in 2015.

He was formerly an MP, first for Wanstead and Woodford between 1987 and 1997, and then for North East Hampshire between 1997 and 2015.

During his time as an MP he served as minister of state for defence procurement, opposition chief whip, shadow secretary of state for trade and, finally, chairman of the Defence Select Committee.

While still an MP, Arbuthnot got involved in the campaign for exposure and justice surrounding the Post Office scandal, in which hundred were wrongly accused and convicted of theft, fraud and false accounting, due to a faulty computer system.

This was after it was brought to his attention by his constituent, Jo Hamilton, who was charged. He went on to lead the cross-party parliamentary group of MPs who came together after their constituencies asked them for help.

In 2015, Arbuthnot called for a judge-led investigation into the Post Office’s handling of the issue, saying: "These are people who have been pillars of the community and have their reputations dragged through the mud. The way they have been treated is an utter disgrace."

In December 2019, a High Court judge ruled that Horizon contained a number of "bugs, errors and defects" and there was a "material risk" that this caused shortfalls in accounts.

Arbuthnot said in a statement in response: "The subpostmasters have been vindicated in every respect. It is an excellent Christmas present, but won at great cost. The cost falls partly on the taxpayer but also heavily on the subpostmasters themselves, who will have their damages reduced by the amount the litigation funders will (justifiably) deduct."

He then called for a further inquiry, which continues to this day.

While Jennings hasn't yet spoken about his role in the series, Toby Jones, who plays Alan Bates, did speak with the real-life James Arbuthnot when he was appearing in the show.

Jones said: "I spoke on the phone to James Arbuthnot, [the former MP for North East Hampshire who played a pivotal role in helping the subpostmasters] about Alan. James was very clear that it has always been a privilege to talk to Alan Bates.

"He looked forward to Alan getting in touch with him on every occasion, because he knew he would learn something and no time would be wasted.

"For all of the appalling injustice and the terrible, ongoing struggle that ordinary people have been thrown into lasting a number of years, a crisis throws up opportunities for heroism. Alan Bates is a proper hero."
