Man, who landed a slap on the face of French President two days ago has been charged to court in a fast-track trial on Thursday.
President Emmanuel Macron was struck on Tuesday while within a crowd during a tour of Southern France.
The perpetrator was not immediately exposed at the time of the incident but was nabbed later that same day and put in custody.
He has been identified as a 28-year-old medieval history enthusiast by the name Damien Tarel.
He faces trial before a magistrate in the southern town of Valence for assaulting a public figure.
Tarel had acknowledged striking Macron while the president was on a visit to a professional training college, but told investigators that he acted “without thinking”, local prosecutor Alex Perrin said in a statement.
The accused also revealed during interrogation that he had been close to the anti-government “yellow vest” protest movement which shook the Macron presidency and held ultra-right-wing political beliefs.
The statement also quoted Tarel saying that he sympathized with the “yellow vest”
“He contends that he acted instinctively and ‘without thinking’ to express his annoyance,” a statement from the local prosecutor’s office said late on Wednesday.
With the charges, Tarel faces a maximum three-year jail sentence and a fine of 45,000 euros ($55,000), although the court will take into account the defendant’s clean criminal record and any expression of remorse.
The attack on the president on Tuesday stunned the country and Macron later described it as an isolated incident, noting that violence and hate were a threat to democracy.
