Speculate as you will

Is it a stunning  shock-horror that one of the grandfathers of the lady who will become next head of MI6 is a Ukrainian who defected from the Red Army during World War II to become an informant for the Nazi regime targeting collaborators with the Soviet occupiers?
    Mildly interesting to most people, maybe, but nothing to do with her life and career.
    But certainly something for the propagandists of Putinstan and their minions to wibble about endlessly on the interweb and elsewhere.
