PARIS (Reuters) - Four months after a heavy electoral defeat, France's National Front is on the verge of a split between its leader and her chief deputy that could open the way to a policy change on the euro as the far-right party seeks to rebrand itself.

Marine Le Pen's relationship with deputy Florian Philippot, for years her closest aide, has become so strained since she lost the presidential election to centrist Emmanuel Macron that far-right experts say it has reached the point of no-return.
