Both the SNP and Plaid Cymru are members of the European Free Alliance (EFA), a European political party comprising regionalist political parties. The EFA co-operates with the larger European Green Party to form The Greens–European Free Alliance (Greens/EFA) group in the European Parliament. Before its affiliation with The Greens–European Free Alliance, the SNP had previously been allied with the European Progressive Democrats (1979–1984), Rainbow Group (1989–1994) and European Radical Alliance (1994–1999).
