Emmanuel Macron has vowed to fight “the forces of division that undermine France” after easily winning the run-off election for the French presidency.
The centrist candidate, 39, defeated the far right’s Marine Le Pen, winning 66.1% of the vote to her 33.9%.
Acknowledging his victory, Mr Macron told supporters he wanted to ensure Le Pen voters “no longer have a reason to vote for an extremist position”.
There has been a palpable sense of relief among European leaders.
Mr Macron was elected on a pro-European Union platform, while Ms Le Pen by contrast threatened to pull out of the single currency and hold an in/out referendum on France’s membership of the EU.
In a speech to jubilant supporters, Mr Macron said: “Tonight you won, France won. Everyone told us it was impossible, but they don’t know France.”
His win makes him France’s youngest president, and overturns the decades-long dominance of France’s two main political parties.
