“This week one of the historic figures in the fight against antisemitism in France gave his views on these ironies of history and politics.
Serge Klarsfeld and his wife Beate helped bring Nazi war criminals to justice, and documented the deportations and deaths of 80,000 Jews from France exterminated in the Holocaust.
Speaking to Le Figaro newspaper, Mr Klarsfeld, now 88, said: "For me the DNA of the far right is antisemitism. So when I see a big party of the far right abandon antisemitism and negationism and move towards our Republican values, naturally I rejoice."
"The far left for its part has always had its own antisemitic tradition. So just as I am relieved to see the RN… take a stand for Jews, so I am sad to see the far left abandon its actions to combat antisemitism."
