1963 Greek legislative election

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. The leader of the Center Union was still refusing to accept the official results of the 1961 legislative elections, the elections of "violence and fraud", according to his aggressive rhetoric. Hence, he refused to legitimise the Parliament and he was inciting public manifestations against Karamanlis and the Palace.

In his "uncompromising struggle", Papandreou was supported by the United Democratic Left (ΕΔΑ), which was the party that suffered the greatest losses in the 1961 legislative elections and it had reasons to believe, that it was hurt by the alleged election fraud.

In his archives, Constantine Karamanlis recognises limited incidents of fraud in the 1961 legislative elections, but he insists that these incidents:

• had not influenced the final outcome, because the National Radical Union had a huge lead,
• had been incited by the Palace and not himself,
• the Party hurt by these incidents was the United Democratic Left (ΕΔΑ) and not the Center Union and his leader, Georgios Papandreou, who knew about the fraud and tolerated it, believing that his party would be favored.

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 the public unable to control the extremists. This failure of the government was underlined by his own legendary apophthegm: "Who's governing this country?"

Because of the slim difference of votes between the two biggest parties and, also, because of the electoral system, no party managed to have an absolute majority in the Parliament. In his later personal notes, as presented in his archives, Constantine Karamanlis justifies his party's narrow defeat with the following arguments:

• His party underestimated the people's fatigue, after so many years of National Radical Union's government and after so many months of political unrest.
• His party had lost the right timing, which slipped away from it just after Pipinelis' government resignation and the appointment of a new interim government.
• The interim government, which conducted the elections, was not really neutral, but it favored in various backhanded ways the Center Union.
• The United Democratic Left (ΕΔΑ) favored the Center Union, convincing a limited but important number of its supporters to vote for Georgios Papandreou.
• His Party should have shaped an alliance with the conservative Progressive Party of Spyros Markezinis. An agreement of this kind would have resulted in a victory of the right-wing alliance.

Just after the elections, Karamanlis left for Paris, with his wife. Noteworthy, he had also left for France, just after his resignation, but he returned, in order to lead his party in the elections.

The outcome of the elections consisted a deadlock. Constantine Karamanlis proposed the formation of a new interim "neutral" government, whose duty would be to conduct new elections. However, Georgios Papandreou was outspoken about his right to form a government of himself, in order to carry out the new elections.

King Paul I followed Papandreou's instructions, giving him the order to form an interim government, whose role would be to lead the country to new elections.

Karamanlis questioned the constitutionality of the King's decision, but, instead of insisting in his opinion, he preferred to resign and leave the country. Following his proposal, the party he founded, the National Radical Union chose Panagiotis Kanellopoulos as his successor.
