Marine Le Pen’s election ban risks a surge in anti-establishment sentiment in France that could undermine efforts to stabilize the nation’s creaky public finances.

The court decision to bar the far-right leader from the 2027 presidential race jeopardizes the delicate peace that has allowed President Emmanuel Macron’s government to pass a budget for 2025. It makes a no-confidence motion in Parliament more likely and potentially hands control of Le Pen’s National Rally to a largely untested 29-year-old.
