May 8 (Reuters) - Independent centrist Emmanuel Macron has been elected French president by a wider than expected margin after defeating far-right Marine Le Pen with about 66 percent of the votes.
The former banker's clear run-off victory will bring relief to European allies who had feared another populist upheaval.
