Whether she can build on this to win in five years’ time, when Mr Macron will not be allowed to run, is uncertain.
What is clear is that she has been more, if not entirely, successful in de-demonising her party, which like Mr Macron’s En Marche, is built around her personality.
Ms Le Pen has vowed to fight on, but once parliamentary elections are over in June, many believe a new and more dynamic face could build on her foundations.
Jordan Bardella, at just 26 years old, could fit the bill in future years. Marion Maréchal, Ms Le Pen’s niece, could also step in, but relations are strained with the National Rally leader after she endorsed Mr Zemmour.
