French citizens living overseas began casting their ballots in the first round of the presidential elections a day ahead of the vote in France.
Voters in Saint Pierre and Miquelon, the French archipelago south of the Canadian island of Newfoundland, Guiana in South America and French Polynesia began voting on Saturday.
French islands Reunion and Mayotte were scheduled to begin voting on Sunday two hours and one hour earlier than the mainland respectively.
The overseas votes are set to be collected and sent to France early to prevent overseas voters from being influenced by the results of the mainland due to time differences.
A blackout on opinion polls was also issued in France at midnight on Friday.
Two out of the eleven eligible candidates will be selected to participate in a runoff vote on May 5.
Emmanuel Macron of the centralist En Marche! party, Marine Le Pen of the far-right Nationalist party and Francois Fillon of the center-right Republican party are among the more popular candidates for the presidency.
France promised tight security at the ballots, including tens of thousands of police and other security personnel on duty, as tensions rose and the threat of terrorism became a focal point prior to the election.
