- 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.
