Venezuelans will head to the polls in the coming hours for a presidential election that current President Nicolas Maduro is expected to win.

He's expected to fend off a challenge by the main opposition candidate, Henri Falcon.

Two other candidates are also in the fray - but the main opposition coalition is boycotting the vote.

The lack of unity in the opposition is seen as a further advantage for Maduro.
