Rattachism

[5] Rattachists argued that in order to preserve their economic prosperity they must unite with France, and that Wallonia as a region was culturally French.

[7] A 2010 Institut français d'opinion publique (IFOP) poll found that if the Belgian political crisis led to the splitting up of Belgium, 66% of the French respondents would support the unification of Wallonia with France.

[8] Modern-day French politicians such as Jean-Pierre Chevènement, Nicolas Dupont-Aignan, Jacques Myard, Marine Le Pen, Jean-Luc Mélenchon and Éric Zemmour have all voiced support for Rattachism.

[11] Another IFOP poll taken in 2010 during the Belgian political crisis found that 32% of Walloons surveyed would support unification if Belgium splits up.

[12] Walloon politicians who have at some point voiced support for the idea are Daniel Ducarme, Jean Gol, Claude Eerdekens and Robert Collignon [fr].
