The European Parliament lifted Marine Le Pen's immunity from prosecution in a vote on Thursday, Reuters reports.
To remind, Le Pen is facing legal action in France following criticism of the center-right mayor of Nice, Christian Estrosi, who filed suit against her for accusing him of being in league with Islamist militants.
To note, Emmanuel Macron, current president of France, has already lost his immunity in March.
It was because of a case over tweets of graphic images of executions by Islamic State.
