Matthias Diependaele in the context of "European Free Alliance"

The European Free Alliance (EFA) is a European political party that consists of various regionalist, separatist and minority political parties in Europe. Member parties advocate either for full political independence and sovereignty, or some form of devolution or self-governance for their country or region. The party has generally limited its membership to centre-left and left-wing parties; therefore, only a fraction of European regionalist parties are members of the EFA. Since 1999, the EFA and the European Green Party (EGP) have joined forces within Greens–European Free Alliance (Greens/EFA) group in the European Parliament, although some EFA members have joined other groups from time to time, for example the New Flemish Alliance which sits with the European Conservatives and Reformists Group.

The EFA is represented in the European Council by Bart De Wever of the New Flemish Alliance, who has served as Prime Minister of Belgium since 2025. Two EU regions are led by EFA politicians: Flanders with Matthias Diependaele of the New Flemish Alliance and Corsica with Gilles Simeoni of Femu a Corsica. Additionally, Scotland is led by John Swinney of the Scottish National Party.
