The office was assumed by the president of the Senate, Pedro Opazo Letelier, who promptly himself resigned (the very next morning) after naming Juan Esteban Montero as his successor.
Since Montero was constitutionally banned from standing as a candidate while still in office, as a way out of the political impasse, and in order to qualify, he resigned his vice-presidency effective on August 20, 1931.
On June 4, 1932, the Air Force, under the leadership of Commodore Grove, rebelled against the government, causing the immediate resignation of President Montero, and the proclamation of the Socialist Republic of Chile.
The executive power was vested in a Government Junta made up of General Arturo Puga (in representation of the military party), Carlos Dávila and Eugenio Matte.
Nonetheless, the opposition to his rule was increasing daily, and finally was forced to resign on September 13, 1932, handing power to General Bartolomé Blanche.
