France's Hollande greets Macron in first meeting since victory

At the European level, he must convince German Chancellor Angela Merkel - who looks on track to win re-election in September after another strong performance by her conservatives in a regional vote on Sunday - to develop a common vision for taking Europe forward. It said the leaked data had been "fraudulently" obtained and that fake news has probably been mingled in with it. In the runoff against Le Pen, he notched up nearly two-thirds of the vote, according to exit polls.

Allegations by Macron's camp that a massive computer hack had compromised emails added last-minute drama on Friday night, just as official campaigning was ending.

In a cursory look at the leaked documents, they appear to be largely mundane day-to-day communications, with a few items so out of character that they might be fakes.

Still, the anti-establishment wave seems unlikely to disappear anytime soon.

Mahjoubi did not respond to requests for comment amid the campaign blackout Saturday.

Le Pen called him up to congratulate him.

"The euro couldn't sustain the rally as it took to consolidating a 3 percent spike since France's presidential vote started two weeks earlier", said Joe Manimbo, senior market analyst, at Western Union Business Solutions in Washington.

The first French territory to vote was Saint-Pierre-et-Miquelon, an archipelago located near Newfoundland. An aide to Obama said Sunday he was not expected to comment on the day of the results.

French voters elected centrist Emmanuel Macron president on Sunday in a decisive rebuke of far-right candidate Marine Le Pen.

He plans to tour European capitals during his first months in charge to set out a "five-year roadmap to give the eurozone a true budget and to create a Europe of 27 for the environment, industry and managing migration".

There is skepticism about Macron's ability to win a majority with candidates from his En Marche movement - "neither of the left, nor right" - alone, meaning he might have to form a coalition. It recalled similar leaks from Hillary Clinton's USA presidential campaign.

"The market already priced in the victory of Macron", said Masafumi Yamamoto, chief currency strategist for Mizuho Securities in Tokyo. Macron walked on to the stage to the strains of "Ode to Joy", the anthem of the beleaguered European Union that he has promised to strengthen after Britain's impending exit.

Casting a blank ballot - traditionally used by disgruntled French voters as a protest vote - usually increases in the second round.

Her father Jean-Marie Le Pen, the founder of the far-right National Front party, is known for racist and anti-Semitic remarks, like describing Holocaust as a detail of history, and has referred to the Nazi occupation in the past as "not particularly inhumane".

And opposition politicians like Le Pen and Mr Wilders have gained a stronger platform from which to promote their messages. One of her aides said the party will change its name.

The 39-year-old former investment banker, who served for two years as economy minister under Hollande but has never previously held elected office, will become France's youngest leader since Napoleon. Without that, Le Pen could be hard-pressed to be more than a disruptive force.

Had she won, she says she would have immediately worked to pull France out of the European Union and North Atlantic Treaty Organisation and put French francs back in the pockets of the French who now shop with the euro currency.
