French National Front leader Marine LePen said she would seek disciplinary action against her father after the 86-year-old exreme-right party founder Jean-Marie Le Pen Jean-Marie Le Pen last week reiterated a past comment that Nazi gas chambers were a "detail of history".
In an interview with an extreme-rightist magazine, he was also quoted as calling France's Spanish-born Prime Minister Manuel Valls "the immigrant" while defending Philippe Petain, leader of France’s war-time government that cooperated with Nazi Germany.
"Jean-Marie Le Pen seems to have descended into a strategy somewhere between scorched earth and political suicide," Marine Le Pen, who took over the party from her father in 2011, said in a statement.
She called on her father to leave politics and said she would oppose his bid to lead the party in the southern region of Provence-Alpes-Cote d'Azur in December regional elections where the party is hoping to make strong gains.
Since taking the FN’s helm, she has tried to rid the anti-immigrant party of its anti-Semitic image and widen its voter appeal as she readies a bid for the French presidential election in 2017. Polls suggest she could make it into the second-round run-off of a presidential election but is unlikely to win.
