And yet, Julie Mugford lied about it! Why would he need to be put under pressure? His statement gives the impression that he was told from 'his' own superior's what would be happening and as the meeting had been prior arranged the details were quite obviously discussed before Dovey was involved - he was after all, only a stand in manager.
I don't see how you can say that she lied about it with any certainty. There are 3 separate accounts, hers, Susan's and Dovey's and his conflicts with theirs. I prefer his because I see him as neutral, but at the same time, since I can't see any reason for them to lie (especially since they couldn't have got away with the lie because of him) I think they were just mistaken.
He specifically states that he made the decision not to prosecute himself.
