Gareth Jenkins and immunity
Telegraph article here https://uk.yahoo.com/news/horizon-tech-expert-helped-convict-215934637.html about his attempts to obtain immunity from prosecution for anything he says to the Horizon inquiry:
"The architect of the faulty Horizon IT system, who gave evidence used to convict sub-postmasters, has demanded immunity before agreeing to appear at the public inquiry.
Gareth Jenkins, who is understood to have been instrumental in developing the software as a senior computer engineer at Fujitsu, is under police investigation over his role in the Post Office scandal.
His testimony given in court cases that the Fujitsu IT system was working correctly was central to convictions and repeatedly used by Post Office lawyers.
Tracked down by The Telegraph to his home in Berkshire, Mr Jenkins, 69, said, when asked if he was sorry for what had happened: “I don’t want to talk. I don’t have anything to say to you.” "

"Prosecutions brought by the CPS
The Telegraph can also disclose that at least 27 prosecutions were brought by the Crown Prosecution service – as opposed to the Post Office – raising serious questions about whether Sir Keir Starmer, the Labour leader, oversaw a number of wrongful convictions during his five-year tenure as director of public prosecutions between 2008 and 2013.
Mr Jenkins had been due to give evidence to the public inquiry twice. But in each occasion it was postponed including as recently as November 2023, when the Post Office disclosed 3,045 documents on the evening before he was due to give evidence. Sources have speculated that the release of the documents was timed to prevent Mr Jenkins giving evidence."
The phrase 'I smell a rat' springs to mind.
