Question: During the 1934 Italian general election, which leader of the National Fascist Party was led to call the results a "second referendum"?
Context: Benito Amilcare Andrea Mussolini ( ; ] ; 29 July 1883 – 28 April 1945) was an Italian politician, journalist and leader of the National Fascist Party ("Partito Nazionale Fascista"; PNF), ruling the country as Prime Minister from 1922 to 1943—constitutionally until 1925, when he dropped all pretense of democracy and set up a legal dictatorship. Italian Fascism (Italian: "fascismo italiano" ), also known simply as Fascism (Italian: "fascismo" ), is the original Fascist ideology, as developed in Italy.  The ideology is associated with a series of three political parties led by Benito Mussolini: the Fascist Revolutionary Party (PFR), founded in 1915, the succeeding National Fascist Party (PNF) which was renamed at the Third Fascist Congress on 7-10 November 1921 and ruled the Kingdom of Italy from 1922 until 1943, and the Republican Fascist Party that ruled the Italian Social Republic from 1943 to 1945.  Italian Fascism is also associated with the post-war Italian Social Movement and subsequent Italian neo-fascist movements. The National List (Italian: "Lista Nazionale" ) also known as "Listone" (literally "Big List") was a Fascist and nationalist coalition of political parties in Italy put together for the 1924 general election, and led by Benito Mussolini, Prime Minister of Italy and leader of the National Fascist Party. General elections were held in Italy on 26 March 1934.  Following a parliamentary reform enacted in 1928 by the Chamber of Deputies and Senate, the elections were held in the form of a referendum, with the Grand Council of the National Fascist Party, now an official state organ, allowed to compose a single party list to be either approved or rejected by the voters.  The list put forward was ultimately approved by 99.84% of voters.  The overwhelming majority provoked Benito Mussolini to dub the election the "second referendum of Fascism." The Republican Fascist Party (Italian: "Partito Fascista Repubblicano" , PFR) was a political party in Italy led by Benito Mussolini during the German occupation of Central and Northern Italy.  It was founded as the successor of former National Fascist Party as an anti-monarchist party.  It considered King Victor Emmanuel III to be a traitor after he had signed the surrender to the Allied powers. The Argentine Fascist Party (Partido Fascista Argentino, PFA) was a fascist political party in Argentina from 1932 until its official disbandment in 1936, when it was succeeded by the National Fascist Union ("Union Nacional Fascista", UNF).  Founded by Italian Argentines, the party was formed as a breakaway faction from Argentina's National Fascist Party ("Partido Nacional Fascista", PNF).  It was based upon Italian Fascism and was recognized by Benito Mussolini's Italian National Fascist Party in 1935.  In the 1930s the party became a mass organization, particularly in Córdoba.  Nicholás Vitelli led the PFA's branch in Córdoba until his death in 1934, whereafter Nimio de Anquín took the leadership of the party.  The PFA's main political allies in Córdoba were the Argentine Civic Legion and the Nationalist Action of Argentina/Affirmation of a New Argentina movement. The following article contains list of Secretaries of Italian Fascist parties founded and led by Benito Mussolini between 1919 and 1945 — namely Fasci Italiani di Combattimento (FIC), National Fascist Party (PNF) and Republican Fascist Party (PFR). The Congress of Verona in November 1943 was the only congress of the Italian Republican Fascist Party, the successor of the National Fascist Party.  At the time, the Republican Fascist Party was nominally in charge of the Italian Social Republic, a small fascist state set up in Northern Italy after the Allies entered Rome.  The Salò Republic was in fact a German puppet state and most of its internal and external policies were dictated by German military commanders.  Nevertheless, Italian fascists were allowed to keep the trappings of sovereignty.  It was under these conditions that they organized the Congress of Verona, ostensibly for the purpose of charting a new political course and rejuvenating the Italian fascist movement. The Italian Nationalist Association ("Associazione Nazionalista Italiana", ANI) was Italy's first nationalist political party founded in 1910, under the influence of Italian nationalists such as Enrico Corradini and Giovanni Papini.  Upon its formation, the ANI supported the repatriation of Austrian held Italian-populated lands to Italy and was willing to endorse war with Austria-Hungary to do so.  The party had a paramilitary wing called the Blueshirts.  The authoritarian nationalist faction of the ANI would be a major influence for the National Fascist Party of Benito Mussolini formed in 1921.  In 1922 the ANI participated in the March on Rome, with an important role, but it was not completely aligned with Benito Mussolini' party.  Nevertheless, the ANI merged into the Fascist Party in 1923. A casa del Fascio, casa Littoria, or casa del Littorio (] ) was a building housing the local branch of the National Fascist Party and later the Republican Fascist Party under the regime of Italian Fascism, in Italy and its colonies.  In major urban centers, it was called the palazzo del Littorio or palazzo Littorio.  "Littorio" means "lictor", the bearer of the "fasces lictorii", the symbol of Roman power adopted by the Fascist party.
