It is not the first time the feminist group has tried to disrupt an event organised by Marine Le Pen.

Following the incident, Femen took to its Facebook page to criticise the politician.
The organisation said: “Nothing in the programme of Marine Le pen promotes the empowerment of women, no proposal was raised to further equality between the sexes.
“Le Pen is a fictitious Republican, she's neither feminist, nor secular, nor for the defence of human rights… yet she is a candidate for the presidential election!”

Outside the Zenith concert hall, where the event was held, anti-Front National protestors rioted throwing flares and missiles.
