Emmanuel Macron: "I am always in favor of people being able to express themselves freely, even if I fight their ideas." Jean-Luc Mélenchon and Éric Zemmour were banned from public meetings in Lille and Brussels. The ban on the conference was denounced by several European heads of government as an attack on freedom of expression and assembly.

The controversial meeting of the European nationalist right in Brussels, banned on Tuesday by local authorities, was finally able to take place on Wednesday after the decision of the Belgian Council of State to invalidate the decree. The organizers of the "National Conservatism Conference" (“NatCon”) had filed an appeal. The conference brings together several leading figures from the nationalist and Eurosceptic camp a few weeks before the European elections. It was initially to be held at the University of Lille, but was ultimately banned because "the conditions were no longer met to guarantee the serenity of the debates."
