Tense French presidential race wraps up ahead of Sunday vote

France's presidential race wraps up a tense campaign Friday after frontrunner Emmanuel Macron filed a legal complaint over rumours that he has an offshore account and both candidates met a stormy reception during final rallies.

Macron and his far-right rival Marine Le Pen have scheduled several press interviews for Friday, the last day of official campaigning before Sunday's run-off vote.

At a final rally Thursday in the northern village of Ennemain, anti-immigration candidate Le Pen told supporters she would give them back the keys to the Elysee Palace.

"France cannot wait five more years to hold its head high," she said.

At an earlier stop in the western town of Dol-de-Bretagne protesters threw eggs at her entourage, although she was not hit.

During a final rally in the southwest town of Albi, pro-European centrist Macron told cheering supporters: "We will keep our promise of change to the end".

The former economy minister was however criticised by some 50 union activists who demanded the abolition of France's controversial 2016 labour reforms.

Macron filed a legal complaint Thursday after Le Pen repeated rumours that he had an offshore account during a particularly bruising TV debate.

The pro-EU Macron and Le Pen battled repeatedly over terrorism, the economy and Europe in Wednesday's TV duel watched by some 16.5 million people.

"I hope that we will not find out that you have an offshore account in the Bahamas," Le Pen said during the debate, which was her last chance to narrow the gap.

Macron would win around 60 percent to Le Pen's 40 percent if the vote were held now, surveys suggest.

The 39-year-old ex-economy minister described his rival's insinuation as "defamation" and after his complaint, French prosecutors launched a probe Thursday into who started the rumour.

Macron's campaign team called it a "textbook case" of "fake news", saying it was spread on Twitter by accounts close to Kremlin-friendly news sites like Sputnik and RT as well as supporters of US President Donald Trump.

Meanwhile, Le Pen's National Front party said her campaign website had been repeatedly targeted by a hacker close to the far-left, who was arrested last week.

The probe into the anti-Macron allegations came as former US president Barack Obama threw his support behind the centrist, saying in a video he "appeals to people's hopes and not their fears".

Obama said Macron had "put forward a vision for the important role that France plays in Europe and around the world" and added "Vive la France!"

During the debate Le Pen branded Macron "the candidate of the elite" while he called her "the high priestess of fear".

After the bruising confrontation, a snap poll by French broadcaster BFMTV found that nearly two-thirds of viewers thought Macron was the "most convincing" of the two, broadly mirroring forecasts for the decisive election on Sunday.

'Brutal and violent' debate

The aggressive and often unruly debate shocked many observers used to a more reserved tone in French political discourse.

The Elabe poll for BFMTV showed that Macron had convinced 63 percent of viewers compared to 34 percent for Le Pen, suggesting she did little to win over new voters.

Le Pen tried to portray Macron as being soft on Islamic fundamentalism, playing to the concerns of many of her supporters after a string of terror attacks in France.

But Macron was in combative form throughout, repeatedly portraying Le Pen's proposals as simplistic, defeatist or dangerous and targeting her proposals to withdraw France from the euro in particular.

The euro policy "was the big nonsense of Marine Le Pen's programme", he said.

Le Pen called the euro, shared by 19 countries in the European Union and blamed by some in France for a rise in prices, "the currency of bankers, it's not the people's currency".

In the first round of the election on April 23, Marine Le Pen finished second behind Macron with 21.3 percent after softening the FN's image over the past six years -- but without fully removing doubt about the party's core beliefs.

She sees her rise as the consequence of growing right-wing nationalism and a backlash against globalisation reflected in the election of Donald Trump in the United States and Britain's shock vote to leave the European Union.
