PARIS — Marine Le Pen, the French far-right leader and former presidential candidate, was charged on Friday in connection with an investigation into whether her National Front party misused funds at the European Parliament.

The charges were confirmed by Rodolphe Bosselut, Ms. Le Pen’s lawyer, in an interview with the BFMTV news channel.

The National Front, led by Ms. Le Pen, is accused of putting staff members who did political work unrelated to the European Union on the European Parliament’s payroll by having them sign up as phony parliamentary aides.

Ms. Le Pen, who until recently was a European representative herself, was charged with breach of trust over accusations that she put her chief of staff and her bodyguard on the European Union payroll at various times between 2009 and 2016. She was also charged with complicity of breach of trust for her wider role as head of the party.
