After the Liberation, he founded the Corriere Lombardo newspaper as well as Costume.
Edgardo Sogno was then elected deputy to the Constituent Assembly during the 1946 general election.
He contested the June 2, 1946 referendum creating the Republic of Italy, deposing numerous appeals before the Corte di Cassazione in the aim of repealing the results of the vote (and restore monarchy).
Although this failed, he became diplomat of the new regime, first in Buenos Aires where Juan Peron was head of state, then in Paris, London, Washington DC and, last, he was ambassador in Rangoon.
While posted to Budapest, Hungary, in 1956, he helped people flee the country after the Soviet Union invaded Hungary and crushed the Hungarian Revolution.

He returned to Italy in 1971, where he founded the Comitati di Resistenza Democratica (Committee of Democratic Resistance), an anti-communist organization of the political center.
Three years later, he was accused by the communist magistrate Luciano Violante of having planned, along with Luigi Cavallo and Randolfo Pacciardi, the Golpe bianco ("white coup d'etat"), a supposed coup.
Following a year and a half of prison, he was freed in 1978, the investigative magistrate declaring that he was in the impossibility to proceed in the trial.
He was later completely exonerated for attempting to plot a coup.

Liberal, monarchist, then admirer of Charles de Gaulle, Edgardo Sogno returned to politics only in 1996, as candidate to the Italian Senate, in Cuneo, for the National Alliance (Alleanza Nazionale) party founded by Gianfranco Fini.
Failing to be elected, he retired to private life.

In his 1998 memoirs, Sogno revealed how he had visited the CIA station chief in Rome in July 1974 to inform him of his plans for an anti-communist coup.
He wrote: "I told him that I was informing him as an ally in the struggle for the freedom of the west and asked him what the attitude of the American government would be," and then: "He answered what I already knew: the United States would have supported any initiative tending to keep the communists out of government."
