In Marine Le Pen's Insane Kippah Ban Defense it's stated that Marine Le Pen is opposed to (male) circumcision:
This becomes most apparent in Le Pen’s views on the headscarf and the yarmulke: While some of her rivals would outlaw these in public schools, Le Pen wants to ban them in all public places. In conjunction with her opposition to ritual slaughter and male circumcision, this would have a much more extreme outcome for religious freedom than anything the mainstream right has ever suggested. In effect, her policies would make it impossible for many French Jews and Muslims to carry out what they perceive as their basic religious duties.
However, I haven't found any mention of that in the English-language Wikipedia article on her political positions or in the French-language Wikipedia article about her. Googling has been unsuccessful, even when using "circoncision marine le pen", as has searching English-language Google News.
