As a rising star in Hungary's far-right Jobbik Party, Csanad Szegedi was notorious for his incendiary comments on Jews: He accused them of "buying up" the country, railed about the "Jewishness" of the political elite and claimed Jews were desecrating national symbols.

Then came a revelation that knocked him off his perch as ultra-nationalist standard-bearer: Szegedi himself is a Jew.

Following weeks of Internet rumors, Szegedi acknowledged in June that his grandparents on his mother's side were Jews — making him one too under Jewish law, even though he doesn't practice the faith. His grandmother was an Auschwitz survivor and his grandfather a veteran of forced labor camps.

Since then, the 30-year-old has become a pariah in Jobbik and his political career is on the brink of collapse. He declined to be interviewed for this story.
