In a two-part investigation, Al Jazeera’s Investigative Unit goes undercover to expose France’s far-right and reveals secret links between violent activists and one of France’s biggest political parties.

Marine Le Pen recently changed the name of the National Front to the National Rally as part of efforts to reform the party’s image and make it more acceptable to French voters.

However, an al Jazeera reporter uncovers close connections between senior politicians in Le Pen’s party and Generation Identity (GI), a far-right youth movement dedicated to expelling Muslims from Europe.
