Marine Le Pen's platform based on 'hatred', says Macron whose campaign was targeted by hackers

French presidential front-runner Emmanuel Macron has launched a political offensive against far-right leader Marine Le Pen, saying her platform is based on "hatred for others" in contrast to his desire to "calm" the country.

Mr Macron and Ms Le Pen, who took the first two spots in Sunday's election first round, are facing off in the May 7 run-off.
