This is the best summary I could come up with:

Mr Roll would go on to play a crucial part in a 2019 High Court case which ruled that bugs could cause errors in the Post Office computer system intended to keep track of transactions in local branches.

Between 1999 and 2015, 700 sub-postmasters and postmistresses - self-employed people who run Post Office branches - were prosecuted for offences such as theft, fraud and false accounting, with some going to prison and others even taking their own lives.

And minutes of a Post Office meeting later uncovered in court show its PR boss Mark Davies directly lobbied senior BBC management to try to stop further negative coverage of the story.

It was explosive testimony that could call into question the convictions of more than 700 sub-postmasters prosecuted on the basis of Horizon evidence, as the denial of the possibility of remote access underpinned the Post Office’s legal position.

A report by consultants Ernst and Young sent to Post Office directors in 2011 warned that Fujitsu staff had “unrestricted access” to sub-postmasters’ accounts, that “may lead to the processing of unauthorised or erroneous transactions”.

PR boss Mark Davies fired off complaints to ever more senior managers at the BBC, and expensive external lawyers were hired with public money to send letters threatening to sue Panorama.
