Defeated French presidential candidate Marine Le Pen claimed a 'historic, massive result' for the far right in Sunday's presidential run-off, despite being soundly beaten by centrist Emmanuel Macron.

But, she added, her National Front (FN) party needed to undergo a "profound transformation" in order to create a "new political force."

Estimates based on partial results showed Macron winning 65-66.1 percent of the vote compared with 35-33.9 percent for Le Pen.

Le Pen said she had called Macron to wish him success.

"I called Mr Macron to congratulate him on his election, and because I have the country's higher interest at heart I wished him success faced with the huge challenges France is facing," she told supporters at a post-election FN gathering in Vincennes near Paris.

The 48-year-old nationalist said her score made the FN the country's "biggest opposition force" and announced she would lead the FN into June general elections.

Le Pen said the contest against the pro-EU Macron had confirmed a new faultline "between patriots and globalists".
