CENTRIST candidate Emmanuel Macron and far-right populist Marine Le Pen have advanced to the French presidential run-off vote, marking a dramatic shift in the country’s political system.

For the first time in modern French history, no mainstream party candidate will advance to the final vote, and a showdown is now set over France’s participation in the European Union.

Macron’s optimistic vision of a tolerant France with open borders and Le Pen’s darker, inward-looking platform calling for closed borders, tougher security, less immigration and dropping the shared euro currency to return to the franc will go head-to-head.

After the results became clear French politicians on the left and right immediately urged voters to block Le Pen’s path to power in the May 7 vote, saying her virulently nationalist anti-EU and anti-immigration politics would spell disaster for France.

Polls putting the two head-to-head in a run-off have consistently forecast a comfortable win for Macron.

A 39-year-old investment banker, he made the run-off on the back of a grassroots start-up campaign without the backing of a major political party.

Supporters of both candidates erupted into wild cheers at their campaign headquarters when the results of yesterday’s ballot emerged.

“We will win!” Le Pen supporters chanted in Henin-Beaumont. They burst into a rendition of the French national anthem, and waved French flags and blue flags with “Marine President” inscribed on them.

But in Paris, protesters angry that Le Pen has advanced into the final vote scuffled with police.

Crowds of young people, some from anarchist and anti-fascist groups, gathered on the Place de la Bastille in eastern Paris as results were coming in from the first round vote.

Police fired tear gas to disperse an increasingly rowdy crowd and riot police surrounded the area.

The absence in the final vote of candidates from either the mainstream left Socialists or the right-wing Republicans party – the two main groups that have governed post-war France – shows a seismic shift in the nation’s political landscape, after an unpredictable and tense campaign.

The vote took place amid heightened security in the first election under France’s state of emergency, which has been in place since the gun and bomb attacks in Paris in 2015.
