The centrist’s emphatic victory, which also smashed the dominance of France’s mainstream parties, will bring huge relief to European allies who had feared another populist upheaval to follow Britain’s vote to quit the EU and Donald Trump’s election as U.S. president.

With the vast bulk of votes counted, Macron had around 65.5 percent to Le Pen’s 34.5 – a gap wider than the 20 or so percentage points that pre-election surveys had suggested.

Even so, it was a record performance for the National Front, a party whose anti-immigrant policies once made it a pariah, and underlined the scale of the divisions that Macron must now try to heal.

After winning the first round two weeks ago, Macron had been accused of behaving as if he was already president; on Sunday night, with victory finally sealed, he was much more solemn.

“I know the divisions in our nation, which have led some to vote for the extremes. I respect them,” Macron said in an address at his campaign headquarters, shown live on television.

“I know the anger, the anxiety, the doubts that very many of you have also expressed. It’s my responsibility to hear them,” he said. “I will work to recreate the link between Europe and its peoples, between Europe and citizens.”

Later he strode alone almost grimly through the courtyard of the Louvre Palace in central Paris to the strains of the EU anthem, Beethoven’s Ode to Joy, not breaking into a smile until he mounted the stage of his victory rally to the cheers of his partying supporters.

His immediate challenge will be to secure a majority in next month’s parliamentary election for a political movement that is barely a year old, rebranded as La Republique En Marche (“Onward the Republic”), in order to implement his program.
