Eleven French presidential candidates are expected to go head to head in a televised debate on Tuesday. If no candidate gains half the votes in the first round of the vote on April 23, the top two will go through to the May 7 run-off. 

Polling for the first round of voting suggests that the favorite to win was conservative candidate Francois Fillon until an investigation into alleged fraud hampered his campaign. He is now in third place behind far-right candidate Marine Le-Pen and centrist Emmanuel Macron. Le Pen is also under investigation for the alleged misuse of European Union funds. Prosecutors have recently opened a probe into a Las Vegas event attended by Macron when he was finance minister.

With just a few weeks to go before voters head to the polls, there's still a lot of unknown variables and almost 40 percent of voters say they're still torn on who to vote for. 

“The US election was already a big joke, I didn’t think we could do even worse in France, and with the various scandals, it’s very difficult to form an opinion. There is really an atmosphere where people are fed up with the left-wing parties and the right-wing parties, and the young are not very interested at all,” said a French citizen.

Polls predict it will be Marine Le Pen and Emmanuel Macron who make it through to the second, and decisive, round of voting, with Macron predicated to take the presidency. But with almost four out of every ten voters saying they still don't know who they are going to vote for or that they may still change their mind, the race is very much still wide open.
