As a result of the Potsdam Conference, where Western Allied governments refused to recognize Groza's administration, King Michael called on Groza to resign. When he refused, the monarch went to his summer home in Sinaia and refused to sign any government decrees or bills (a period colloquially known as "greva regală"—"the royal strike"). Following Anglo-American mediation, Groza agreed to include politicians from outside his electoral alliance, appointing two secondary figures in their parties (the National Liberal Mihail Romniceanu and the National Peasants' Emil Hațieganu) as Ministers without Portfolio (January 1946). At the time, Groza's party and the PCR came to disagree on some issues (with the Front publicly affirming its support for private land ownership), before the Ploughmen's Front was eventually pressured into supporting Communist tenets.
