The 11 men and women hoping to be France's next president are appearing on national television seeking to sway voters in the nail-biting, unpredictable election campaign.

The candidates will each have 15 minutes Thursday night individually to answer questions about their stances, along with a brief conclusion at the end, in a prime-time program on France 2.

The four top candidates — centrist Emmanuel Macron, far-right Marine le Pen, conservative Francois Fillon and far-left Jean-Luc Melenchon — will be seeking to impress the 30 percent of French voters who are still undecided.

The French presidential race's outcome is increasingly uncertain just three days before Sunday's first-round vote. The two top vote-getters on Sunday will advance to the May 7 presidential runoff.
