Emmanuel Macron comfortably defeated far-right rival Marine Le Pen, heading off a political earthquake for Europe but acknowledging dissatisfaction with his first term and saying he would seek to make amends.
His supporters erupted with joy as the results appeared on a giant screen at the Champ de Mars park by the Eiffel tower.
Leaders in Berlin, Brussels, London and beyond welcomed his defeat of the nationalist, eurosceptic Le Pen.
With 97% of votes counted, Macron was on course for a solid 57.4% of the vote, interior ministry figures showed. But in his victory speech he acknowledged that many had only voted for him only to keep Le Pen out and he promised to address the sense of many French that their living standards are slipping.
“Many in this country voted for me not because they support my ideas but to keep out those of the far-right. I want to thank them and know I owe them a debt in the years to come,” he said.
“No one in France will be left by the wayside,” he said in a message that had already been spread by senior ministers doing the rounds on French TV stations.
Two years of disruption from the pandemic and surging energy prices exacerbated by the Ukraine war catapulted economic issues to the fore of the campaign. The rising cost of living has become an increasing strain for the poorest in the country.
“He needs to be closer to the people and to listen to them,” digital sales worker Virginie, 51, said at the Macron rally, adding he needed to overcome a reputation for arrogance and soften a leadership style Macron himself called “Jupiterian”.
Le Pen, who at one stage of the campaign had trailed Macron by just a few points in opinion polls, quickly admitted defeat. But she vowed to keep up the fight with parliamentary elections in June.
