Things continue to be challenging for French President Emmanuel Macron as he was slapped publicly by one French citizen probably amid his rising stance against Islamic Terrorism.
Mr Macron's centrist party is projected to gain more than 10% of the vote - just enough to take part in the second round next weekend.
Ms Le Pen's far-right National Rally has also fallen short of expectations. Both are trailing the conservative party, Les Républicains.
More than 15,700 candidates are in the race for 4,100 seats as voters elect their representatives for 13 mainland regional councils of France. The vote is seen extremely important because the presidential elections are scheduled for April 2022 and this is the first time La République en Marche- Macron's party is contesting the regional elections.
