Mr Macron won by 66.06% to 33.94% to become, at 39, the country’s youngest president.
Emmanuel Macron was elected president of France on Sunday with a business-friendly vision of European integration, in a resounding defeat of Marine Le Pen, the far-right nationalist who threatened to pull out of the European Union.
The centrist’s emphasized victory, which also smashed the dominance of France’s mainstream parties, will bring huge relief to European allies who feared another populist disturbance following Britain’s vote to quit the EU and Donald Trump’s election as US president.
Macron – the 39-year-old former investment banker who served for two years as economy minister but has never previously held elected office – will now become France’s youngest leader since Napoleon with a promise to transcend obsolete left-right divisions.
“A new page in our long history has turned tonight,” said Macron in a brief address to the press after the results were proclaimed.
“I want it to be that of rediscovery of hope and trust.”
He promised to “fight the divisions that undermine France” and to “rebuild the links between Europe and its citizens”.
Mr Macron’s win ends the decades-long dominance of the two traditional main left-wing and right-wing parties.
He said that a new page was being turned in French history.
“I want it to be a page of hope and renewed trust,” he said.
Mr Macron said he had heard “the rage, anxiety and doubt that a lot of you have expressed” and vowed to spend his five years in office “fighting the forces of division that undermine France”.
He said he would “guarantee the unity of the nation and… defend and protect Europe.”
Thousands of Mr Macron’s supporters gathered to fete outside the Louvre museum in central Paris and their new president later joined them.
In his address to the mob, he said: “Tonight you won, France won. Everybody told us it was impossible, but they don’t know France.”
But he said a number of times that the task facing him and the country was tremendous.
He said: “We have the strength, the energy and the will – and we will not give in to fear.”
His mention of Ms Le Pen drew loud boos, and he said he would do all he could to assure in future there would be no reason to vote for extremism.
