PARIS (Reuters) - Marine Le Pen said on Sunday she no longer wanted her father to speak on behalf of the French far-right National Front party that he founded and she leads, a day before he may be sanctioned by the party for his comments about World War Two.

Jean-Marie Le Pen faces a party disciplinary hearing on Monday for repeating his view that Nazi gas chambers were a mere "detail" of the war and for defending Philippe Petain, the leader of the French war-time government that cooperated with Nazi Germany.
