It was replaced on April 3, 1967 by another interim government under Panagiotis Kanellopoulos, who was the active leader of the National Radical Union and was still supposed to organize a fair election. There were many indications that Papandreou's Centre Union would not be able to form a working government by itself in the scheduled elections. There therefore existed a strong possibility that the Centre Union would be forced into an alliance with the socialist United Democratic Left. The sense of a "Communist threat", along with putschist tendencies in some nationalist fractions of the Hellenic Armed Forces, led to a coup d'état on April 21, 1967 that which established a military dictatorship, better known as the "Regime of the Colonels".
