• First results estimates at 1800 GMT
  • Macron with slightly growing lead in opinion polls
  • Choice between pro-Europe centrist, far-right eurosceptic

PARIS, April 24 (Reuters) – The French voted on Sunday in an election that will decide whether pro-European Union, centrist President Emmanuel Macron keeps his job or is unseated by far-right eurosceptic Marine Le Pen in what would amount to a political earthquake.

Opinion polls in recent days gave Macron a solid and slightly growing lead as analysts said Le Pen – despite her efforts to soften her image and tone down some of her National Rally party’s policies – remained unpalatable for many.

But a surprise Le Pen victory could not be ruled out. With polls showing neither candidate able to count on enough core supporters to win, much will depend on those still weighing up anxiety about the implications of a far-right presidency against anger at Macron’s record since his 2017 election.

A Le Pen victory would mark a political upheaval for Western democracies on a par with Brexit or the U.S. election of Donald Trump in 2016, ending decades of rule by mainstream French leaders and bringing a new threat to the future of the European Union.

Polls opened at 8 a.m. (0600 GMT) and will close at 8 p.m. (1800 GMT). Initial projections by pollsters are expected as soon as polls close.

With three hours of voting left, 63.23% of voters had cast their ballots – two points down on 2017 when final turnout was already at its lowest point for nearly half a century.

Hugo Winter, a 26-year-old salesman in Paris, said he would be among those who would not bother to cast a vote.

“I don’t see the point in choosing between two things that don’t correspond to my ideas,” Winter said as he did some morning food shopping. “We live in a parallel world. The politicians don’t represent the people.”

In the town of Sèvres just outside Paris, Jamila Bendjilali, a 58-year-old technical engineer, said she switched her vote to Macron “without hesitation” after voting for the hard-left Jean-Luc Melenchon in the first round to give the left a boost.

In Douai, a mid-sized town in northern France where Le Pen was ahead of Macron in the first round of voting two weeks ago, pensioner Andrée Loeuillet, 69, said she had voted for Macron, as she did on April 10.

“He has his faults but he has qualities too. He is the one best placed to continue, we are living through difficult times,” she said.

Macron, 44, who won against Le Pen in the last presidential election five years ago, has warned of “civil war” if Le Pen – whose policies include a ban on wearing Muslim headscarves in public – is elected and has called on democrats of all stripes to back him.

Le Pen, 53, focused her campaign on the rising cost of living in the world’s seventh largest economy, which many French say has worsened with the surge in global energy prices. She has also zeroed in on Macron’s abrasive leadership style, which she says shows an elitist contempt for ordinary people.

“The question on Sunday is simple: Macron or France,” she told a rally in the northern town of Arras on Thursday.

Among early voters in the village of Souille, near the northwestern town of Le Mans, civil servant Pascal Pauloin, 56, said he had voted for Le Pen out of disenchantment with Macron.

“I am very disappointed. Our France has not been working well for years. Macron has done nothing for the middle classes, and the gap with the rich is getting ever wider,” he said.

Le Pen, who has also been criticised by Macron for her past admiration of Russian President Vladimir Putin, rejects accusations of racism. She said her plans to give priority to French citizens for social housing and jobs and scrap a number of welfare benefits for foreigners would benefit all French, independently of their religion or origins.

Jean-Daniel Levy, of Harris Interactive pollsters, said opinion surveys showed Le Pen was unlikely to win, because that would require huge shifts in voter intentions.

If Macron prevails he will face a difficult second term, with none of the grace period that he enjoyed after his first victory, and protests likely over his plan to continue pro-business reforms, including raising the retirement age from 62 to 65.

If she unseats him, Le Pen would seek to make radical changes to France’s domestic and international policies, and street protests could start immediately. Shockwaves would be felt across Europe and beyond.

Whoever comes out on top, a first major challenge will be to win parliamentary elections in June to secure a workable majority to implement their programmes.
