- Nicolas Sarkozy faces challengers including Francois Hollande and Jean-Luc Melenchon
France prepared Saturday to vote in presidential elections that see incumbent Nicolas Sarkozy pitted against challengers including Socialist candidate Francois Hollande.
Voting started Saturday in France's overseas territories, including Guadeloupe, French Guyana, Martinique and French Polynesia.
Voters in mainland France will go to the polls Sunday.
Under French law, no political campaigning of any kind is allowed on the day before the election and no opinion polls can be published.
Ten candidates are on the ballot in the first round of voting.
As well as Sarkozy and Hollande, they include Jean-Luc Melenchon on the extreme left, Marine Le Pen on the extreme right, Francois Bayrou, a centrist, and Eva Joly, for the Greens.
If no candidate wins an absolute majority, a runoff election between the two with the most votes will take place on May 6.
The economy and jobs have been key election issues, as France struggles to overcome low growth and a 10% unemployment rate.
