According to France Bleu Béarn Bigorre, Lassalle is charged with violations of the electoral code, which could have influenced the voting results.
During the second round of elections, the presidential candidate, while at the polling station in the commune of Lourgyos Isher, said that he was abstaining from voting.
A video of the public statement has gone viral on social media.
It is assumed that in this way Lassalle influenced other voters, which is forbidden to do on election day.
Earlier it became known about the victory of Emmanuel Macron in the elections with a result of 58.55% following the counting of 100% of the votes.
His rival Marine Le Pen won 41.45% of the vote.
