European Federalist Party
The European Federalist Party (abbreviated as PFE in French, EFP in English) is a French political party and was, before its 2016 break-up, a European political alliance founded on 6 November 2011 in Paris. The EFP is one of the first European-oriented political parties that openly defends European federalism and is not a coalition of pre-existing national parties.
