The planned revolution would begin in Padang, but a government-security clampdown at the beginning of 1926 which ended the right to assembly and led to the arrest of PKI members forced the party to go deeper underground. Dissention among PKI leaders about the timing and course of the revolution resulted in poor planning. Tan Malaka, the Comintern's agent for Southeast Asia and Australia, did not agree with the plot (partly because he believed that the PKI had insufficient mass support). As a result of these divisions, the revolution was postponed in June 1926.
