So it was basically Christine Legarde (maybe). You know what is funny? A search of that specific quote only returns the FT atricle:
Christine Lagarde "Poroshenko will have to come up with something very meaningful" - Search (bing.com)
What's funnier is that the quote in your pic says, after "perhaps even a change in the much maligned prosecutor's office" HE said. Last time I checked, Legarde is a "she." So who actually said that, because it seems like an unattributed quote injected for some reason to make it look like Legarde was after Shokin. I smell a rat!
The EU (as I demonstrated) thought Shokin was okay, and even Obama administration officials were praising him right up until Biden engineered his ouster. You got anything besides that weird FT article to back up your claims here?
