As he mentions the name of defeated opponent Marine Le Pen, the crowd boos. "Don't boo!" he responds. 

"I will do everything to ensure they don't feel the need to vote for extremes."

Marine Le Pen made several big mistakes in the two weeks before the run-off vote, says French TV website Franceinfo.

• She upstaged Emmanuel Macron at a washing machine factory threatened with closure at Amiens but only stayed 15 minutes for photos.
• Her policy on leaving the euro became muddled after she went into alliance with defeated candidate Nicolas Dupont-Aignant. She had to change her timetable on leaving the single currency.
• She plagiarised part of a speech given a fortnight earlier by centre-right François Fillon - and was ridiculed for it. The tweet below says: "When you haven't done your homework but you're trying to get out of it."

• Then there was the angry TV debate in which she accused Macron of being the candidate of savage globalisation and job insecurity", among many other faults. She may have ticked all the boxes for her own supporters but came across as aggressive to others.
• On the final day of campaigning on Friday she was booed on a visit to Rheims. Not a happy ending.

Macron thanks thousands of supporters gathered at The Louvre: "France won," he tells cheering crowd.

However, the rabbi urged the political class to take note of the anger many voters feel and do something about it.

This pollster highlights interesting voting patterns according to levels of education: the higher the degree, the stronger Macron's appeal. Le Pen does best among those who haven't completed secondary school - but even among then, she is beaten by Macron.

Macron got a staggering 92% of the votes cast by French expatriates in the US who number about 300,000 according to the French government.

German Chancellor Angela Merkel had a "very warm exchange" of about 10 minutes on the phone with Emmanuel Macron, his aides tell AFP. Her spokesman Steffen Seibert tweeted earlier that it was a victory for a "strong and united Europe".

And while we're talking elections, Mrs Merkel is in a bit of a party mood herself. Her CDU party defeated the rival centre-left SPD on Sunday in the somewhat smaller northern state of Schleswig-Holstein.

A big question mark over this election was always going to be how many people would turn up to vote. The projections say turnout was about 74% - the lowest figure in a presidential second round since 1969. 

For a start, neither candidate was from the two mainstream parties - and France is in the middle of a holiday weekend. And far-left leader Jean-Luc Mélenchon, who attracted 19% of the vote in the first round, couldn't bring himself to back either candidate openly.

Pierre Gas, who has lived in the UK since 1993, has always voted for a Republican candidate. He told the BBC he was disappointed that François Fillon did not get through to the second round:

France's president-elect vows a "revival of public life" and says he will focus on work, school and culture to build a better future.  

The euro rallied in early trading on Asian markets, reaching its $1.1023 - its highest level since November. Mr Macron, a supporter of the EU, convincingly defeated Eurosceptic Marine Le Pen.
