Macron stretches lead as French presidential campaign enters final day
The election is seen as the most important in France for decades with two diametrically opposed views of Europe and France's place in the world at stake.
The National Front's Le Pen would close borders and quit the euro currency, while Macron, who has never held elected office, wants closer European cooperation and an open economy.
According to an Elabe poll for BFM TV and L'Express, Macron will get 62 percent of the votes in the second round compared to 38 percent for Le Pen, an increase of three points for the centrist candidate compared to his projected score in the last Elabe poll.
The showing is Macron's best in a voting survey by a major polling organisation since nine other candidates were eliminated in the first round on April 23.
The survey was carried out after a rancorous final televised debate between the two contenders on Wednesday, which Macron was seen as having won by French viewers, according to two recent polls.
A separate poll by Odoxa said a quarter of the French electorate was likely to abstain in Sunday's vote, many of them left-wing voters disappointed after their candidates missed reaching the runoff.
