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.
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.
Nevertheless, King Paul I preferred to appoint an interim government, led by one of Karamanlis' closest colleagues, Panagiotis Pipinelis, whose role would be to pass a new electoral law, accepted by the main party of the opposition, and to put under control the political unrest.
Then, the King, under the pressure of Papandreou and disregarding Karamanlis' instructions, appointed a new "neutral" interim government, which would carry out the 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.
