After yesterday's evidence, I'm feeling a little sorry for Gareth Jenkins. From Second Sight's evidence, he sounds like one of those backroom engineers who just wants to get on with making stuff work, and that he's been sucked in to do the dirty work of the people politicking around him.
That said, if he told an actual lie on oath, rather than being fed words and having them seized on and misused, as Second Sight described happening to the them with "systemic problems", then he is culpable.
Shall await with interest.
Yesterday was so consistent with all we've seen of Paula Vennells' manipulation techniques, especially that email (perhaps not directly from her) telling SS, "The answer you need to give is no," when it clearly wasn't!
And POL's insertion of the term "systemic problems" into SS's investigation, right at the start. As SS said, it wasn't their term, but they used it because PO were using it; then the moment they used it in their interim report (which was just intended to be a holding report, to show the MPs they were actually getting work done), POL seized on it and pretended that was their clean bill of health.
Reminds me of Rupert Murdoch's misuse of an "investigation" they commissioned from lawyers, Harbottle & Lewis. The lawyers were hired to look for wrongdoing A, didn't find any of that but plenty of wrongdoing B – and Newscorp seized on their report to claim they'd been given a clean bill of health.
