Bardella has announced a libel suit against Mediapart following the publication of an article that alleges he uttered antisemitic remarks in 2013.

Mediapart says it spent months reviewing dozens of written conversations allegedly from Bardella’s youth, authenticating them through witness statements and a larger documentary base. The alleged remarks include phrases such as "All banks are owned by Jews" and calls for a "new world order dominated by Israel." Bardella insists the story is fabricated and a political maneuver to destabilise the National Rally’s campaign ahead of the presidential election.

Marine Le Pen has defended Bardella, describing the claims as "weird" and likely a forgery, while corruption allegations within the party are brought up by former members purged for antisemitic views. The national party’s leadership maintains that it has purged extremist elements and now positions itself as a shield for Jewish communities.

The incident precedes a poll that shows Le Pen leading in the first round of the election, with expectations that she will secure a significant majority in the second round over radical left candidate Jean‑Luc Mélenchon. Amid her rising popularity, the RN’s image crisis may intensify if the alleged remarks become credible.
