Who is Raphael Glucksmann, winner of the French left presidential primary?

With just six months to go to presidential polls in France, a coalition of centre left parties have chosen their candidate… It's EU lawmaker, Raphael Glucksmann. The 46 year old tells voters he stands for a break with Macronism, a break with the far left of candidate Jean Luc Melenchon and that he's the candidate who can defeat the far right… though opinion polls suggest that in a second round run off he would not beat far right candidate Marine Le Pen.
