Olli Heinonen, IAEA Deputy Director for Safeguards, resigned today, effective at the end of August, for “personal reasons.”

No word yet on a replacement or how this relates to the past few years of internecine warfare
between Safeguards and Expo.

This blog has been more blunt than most in worrying about divisions within the IAEA, but I have always liked and respected Heinonen. I am definitely sorry to see him go.
