On 1 October 1933, Socialist left leader Largo Caballero spoke out against Lerroux's Republicans, suggesting the reform programme of the government, and thus the basis for the Republic itself, was under threat. He warned that if the government itself were the threat, the Socialists would have to withdraw support for it.Preston (1994). p. 177. The following day another Socialist leader, Indalecio Prieto, declared that the Socialists would no longer participate in government, which precipitated its collapse. Alcalá Zamora, who became President in 1931, now requested that Republican Martínez Barrio form a new government. Socialist opposition on both constitutional and ideological grounds meant the PSOE withheld its support for the Barrio government, which was formed on 8 October, but called for fresh elections to be held on 19 November 1933.Preston (1994). p. 178.
