ReutersPARIS (Reuters). -The French far right failed to win a single regional election on Sunday, exit polls revealed. This deprived Marine Le Pen, its leader, of a chance of proving that her party is ready for power ahead next year's presidential elections. The far-right Rassemblement National party saw the southern Provence-Alpes-Cote d'Azur as its best chance to secure its first-ever regional power base. But parties from all sides united in a "republicanfront" to stop it. His party did not win a single regional election in what was also a humiliating night for President Emmanuel Macron.
