I take it Bonomi didn’t quit?
Nope.
From Wiki:
Bonomi came near to resignation in November 1944 over war strategy, but stayed on as Prime Minister at the urging of the British government of Winston Churchill. He remained Prime Minister until 1945, by which time World War II in Europe had ended, and stayed active in the Italian government after that moment, serving on the Constituent Assembly's committee on treaties, and also representing Italy in councils of foreign ministers until 1946. In 1948, he became President of the Italian Senate, and served in that position until his death.
