A hyperthetical thought has just struck me and because I don't know where to post it, I guess here is as good a place as any.
Pre 1960something there was a death sentence, which undoubtedly Jeremy would have received. This would not have stopped people fighting to clear his name, as some of us now are. This being accomplished, I imagine it would give Jeremy a choice about reclaiming his lost assets, which, if he is said to be innocent, must be seen as being having been illegally gained.
Upon the granting of a Queen's Pardon, what would happen to those assets? Surely a QP wouldn't be worth the paper it was written on if there were those still allowed to profit from the proceeds gained from the imprisonment and execution, possibly with their help, of an innocent man?
