The Democratic Social Movement (DIKKI; Greek: ΔΗΚΚΙ – Δημοκρατικό Κοινωνικό Κίνημα, Dimokratiko Koinoniko Kinima) is a social-democratic[5] political party in Greece.

That decision led to a conflict between the party leader and the National Committee, who voted against the dissolution; there are accusations that Tsovolas went through these actions, because he was planning to be readmitted in PASOK in the near future.

Moreover, DIKKI participated in All Workers Militant Front (PAME), a trade unionist coordination centre closely related with KKE.

Although it was expected that co-operation between the two parties would become permanent, on August 22, 2007 DIKKI announced that it was participating in the Coalition of the Radical Left (SYRIZA),[8] which received 5.04% of the vote in the legislative election held on September 16, 2007.

It would remain affiliated until June 2019, when it joined an electoral coalition with the United Popular Front and Agricultural Livestock Party of Greece.
