(COMBO) This combination of pictures created from file photographs on February 21, 2017 shows 2017 French presidential election candidates (L-R and arranged in alphabetical order) Francois Fillon of the Les Repubilcains (LR) Party, Benoit Hamon of the Socialist Party (PS), Marine Le Pen of the far-right National Front (FN)Emmanuel Macron of the En-Marche movement and Jean-Luc Melenchon of the far left coalition "La France insoumise". France's presidential election moves into high gear on March 20, 2017, when the top five contenders face off in a TV debate that could help sway legions of undecided voters, a month before they go to the polls. This is the first of three debates ahead of the April 23 opening round in France's most unpredictable election in decades. / AFP PHOTO / JOEL SAGET
