Jean-Marie Le Pen had increasingly become a burden on the party he founded. His provocative remarks often landed himself, and the National Front, in hot water. On several occasions he described the gas chambers in Nazi concentration camps as a "detail of history" - and was convicted on charges of racism. Marine Le Pen wants the National Front to shed this rabble-rousing image, preferring to focus on immigration restrictions, concern about Islam, and skepticism about the EU. But Jean-Marie Le Pen is refusing to be silenced.
