By my estimates that is now 12M hoovered since the strategic review announcement two weeks ago. I've nor personally met Tony, but my understanding is that he doesn't invest his own money unless there is a fairly decent chance of multi bagging.
Interesting that there hasn't been an announcement for Neil, however it may be the case that he isn't able to trade due to ongoing discussions he may be having with parties related to the change in strategic direction.
