*How it happened in literally every country with a fascist government, ever (unless they were militarily occupied by another fascist country).
Examples?
Italy 1922 > As Prime Minister, the first years of Mussolini’s rule were characterized by a right-wing coalition government composed of Fascists, nationalists, liberals, and two Catholic clerics from the People’s Party.
Romania 1937 > However, the [conservative National Peasants’ Party] signed a temporary cooperation agreement with the fascist Iron Guard ahead of national elections in 1937, sparking much controversy among its own voters.
Yugoslavia 1925 > Nonetheless, shortly after the election, there were negotiations between Radić and King Alexander’s envoys. The talks ended in Radić renouncing republicanism and accepting the monarchy in return for his release and participation in a coalition government led by the People’s Radical Party (NRS).
Spain 1936 > The FET y de las JONS began as the Spanish Falange, a Falangist party, The Council of National Syndicalist Offensives, a national syndicalist party and Traditionalist Communion, a Catholic monarchist party, three parties that were becoming relevant in Spanish right wing politics before the civil war.
Portugal 1926 > Historians have considered that the coup had wide support, including all political parties at the time except for the Democratic Party, Portuguese Communist Party, the Portuguese Socialist Party, the Seara Nova group, General Confederation of Labour, and the Democratic Leftwing Republican Party (i.e. every party except leftists)
Greece 1935 > For the 1935 election, Metaxas’ party joined other monarchist parties in an electoral coalition known as the United Royalists that called for the restoration of the monarchy. The Freethinkers’ Party won only seven seats in the election. Nevertheless, a monarchist government was formed in Greece in 1935, resulting in the restoration of King George II of Greece as head of state.
Austria 1934 > In the process of establishing the so-called Austro-fascist dictatorship, Christian Social Chancellor Engelbert Dollfuß founded the Patriotic Front (Vaterländische Front) on 20 May 1933, merging the CS with the Landbund, Heimwehr and other conservative groups.
