Centre Union – New Forces (EK-ND, Greek: Ένωσις Κέντρου-Νέες Δυνάμεις (Ε.Κ.

), Enosi Kentrou-Nees Dynameis) was the continuation of the Centre Union party of George Papandreou after the military junta.

It was the merger of a Centre Union fraction led by Georgios Mavros and the Movement of New Political Forces (KNPD).

With the death of the old centrist leader George Papandreou in 1968, who achieved massive support for his centre party Center Union before the coup, and the creation by Andreas Papandreou of socialist PASOK, the old center had lost its appeal to both new and old voters.

Also, the abolition of the Greek monarchy in 1974, through a referendum proclaimed by Constantine Karamanlis, deprived the anti-royalist center parties of a popular cause and an issue which had defined their identity.
