Parliamentary elections were held in Greece on 3 November 1963. They resulted in a narrow victory for the Center Union of Georgios Papandreou after three consecutive victories of Konstantinos Karamanlis and his National Radical Union and after 11 years, during which the conservative parties (Greek Rally and its successor, the National Radical Union) ruled Greece. Background The early elections were caused by Karamanlis' resignation. It was a fierce confrontation with King Paul I and the royal family that led to the fall of the right-wing government. The King (influenced by the Queen Frederika and his son Constantine, according to Karamanlis' later argumentation) didn't follow the prime minister's instructions, concerning an official visit of the royal family to the United Kingdom. The King's stance outraged Karamanlis, who submitted immediately his resignation. The political unrest was also exacerbated by Georgios Papandreou's fierce opposition.

Another incident, which blackened the image of the National Radical Union's government was the killing of the deputy of the United Democratic Left (ΕΔΑ), Grigoris Lambrakis. Karamanlis denied any involvement of his government in the killing and he demanded the immediate intervention of the justice. Indeed the resulting investigation by Christos Sartzetakis proved that there was no involvement of the government in the attack. Nevertheless, the fact that some far-right fractions were proven to be guilty for the killing harmed Karamanlis, who seemed in the eyes of
