Before discovering his grandmother was Jewish, Csand Szegedi was one of the most prominent Hungarian extreme right-wingers.

In 2006, just 24 years old, he became deputy chairman of Jobbik, the third party in the country, strongly nationalist and anti-Semitic.
A year later he contributed to the formation of the Magyar Grda (Hungarian Guard), a paramilitary group later outlawed and known for the marches against Roma and the protests against the World Jewish Congress.
It was only when an ex-con with some grievance against him has stumbled into the birth certificate of his grandmother that the Szegedi political career is over.
His grandmother, he discovered, had survived Auschwitz, and his grandfather was interned in several Nazi concentration camps.
When the news became public in June of 2012, Szegedi was forced to resign.
In the new documentary Keep Quiet, directors Sam Blair and Joseph Martin recount what happened later, when Szeged began to build a new identity as an orthodox jew.
The documentary is a fascinating portrait of a man in crisis, but it is also a story about identity, trust and forgiveness.
A fascist longtime can really become a jew?
And the Jewish community should accept him as one of them?
I talked to Sam Blair before the screening of his documentary at the Jewish Film Festival in London.
VICE: Hello Sam.
How did you find the story of Csand and how you came to make this documentary?
Sam Blair: Alex, our producer, was in Hungary to work on a documentary about the rise of anti-Semitism.
While he was doing research there was the case of Csand.
It's a powerful story that allowed you to look at the problem of anti-Semitism and the rise of the extreme right in Hungary from the point of view of a tormented man, starring in a big and unexpected change of course.
Have you started working on the film shortly after the affair became public dominoes.
Why do you think Csand wanted to participate in such a difficult moment in his life?
When the scandal broke, Csand was put so ridiculous that in some ways she had nothing to hide.
And he's a person who likes to be the center of attention.
Stand in front of a camera makes him happy, he wants that others are to listen and likes to hear their opinions, even if they are negative.
Also I think he wanted to have the chance to tell his side of the story.
How was it received by the Orthodox Jewish community, when he decided to join it?
There have been very different reactions.
As seen in the documentary, some have accepted it.
But many people, the majority, have felt offended by his decision; They wanted nothing to do with him.
One of the best scenes is when Csand goes to visit Auschwitz in the company of a Holocaust survivor.
In the documentary is clear that Csand struggles to come to terms with his old belief of extreme right-as-denier its earlier opinion on the Holocaust.
One can say that the film is about a man who goes through a phase of transition and inner conflict?
I think the film Csand monsters while crossing a sort of gray area in which still has the remains of the belief system which it joined for life.
It's not an easy transition, and it is strange to see him at times say things that seem out of the mouth of the old Csand.
You wonder if his intentions are sincere and if we think seriously.
But I think it also shows that such a change can not happen overnight.
One of the things that make it so amazing is that the change of Csand seems more concerned to take possession quickly of his new identity as Orthodox jew that does not seriously confront her past.
I think the personality and the ego Csand are so developed that he needs a strong identity.
Of course, the story in which he believed and on which it based its identity proved to be false, but I think it's the kind of person who needs extreme.
It could give a much more moderate in his jew identity, but chose not to.
It tends to take it like a medal.
That's what it makes it an interesting and problematic character.
But from my point of view as a director it makes it fascinating because it creates conflict.
Towards the end of the documentary he is asked if it continues to be an orthodox jew and he shrugs and says, "I do not know."
It's a strange and ambivalent ending that does not seem too much in line with the rest of the film.
Explain it to me?
I think they do the opposite, ie a documentary that will eventually give a definitive answer to the questions raised by the experience of Csand, would have been wrong.
It's going through a phase of change.
It is important to accept that a person can be both one thing and its opposite.
Csand as a character is a bit 'a puzzle.
This is why the ending is ambiguous, and I think it would be necessarily so.
Do you think Csand has changed in the course of the documentary?
When we finished the movie I saw Csand behave in a very humble way, and I think this is a sign of change.
First he was an incredibly self-confident man, was a stage animal and had great confidence in what was and what he believed in.
Then he took all these things and put them into question.
