The Calais refugee camp ("Camp de la Lande" or "Calais Jungle") existed from January 2015 to October 2016, coinciding with the peak of the European migrant crisis. The camp drew global media attention and became a significant local issue.

Marine Le Pen became a member of the French Parliament in 2017 by winning the election in Pas-de-Calais's 11th constituency. Prior to 2017, this constituency consistently elected representatives from the left-wing Socialist Party (PS) and the French Communist Party (PCF). Similarly, in 2017, the 7th Constituency, which included the Calais camp, shifted from the left-wing PS to the right-wing LR party.

How big of a role did the Calais refugee camp play in Le Pen's 2017 election victory? I've tried doing my own research but couldn't locate a definitive answer.
