Afterwards, he served as the "formateur" of the First Ali Sastroamidjojo Cabinet, completing the cabinet after 58 days of parliamentary crisis. Wongsonegoro received mixed reception as formateur, with nationalist and communist groups in favour and Muslim and socialist groups against him. Communist Party leader Dipa Nusantara Aidit, a hearty supporter of Wongsonegoro, spoke extremely softly (and thus, in Javanese culture, politely) to him at public meetings, to the point that at times the formateur "was obliged to ask another participant to be [Adiet's] microphone". Meanwhile, the Masyumi Party was staunchly against him, expressing concern for his attempt to keep the Socialist Party out of the cabinet. When he eventually finished forming the cabinet on 31 July 1953, he had lost support from Christian political parties and Masyumi, replacing their candidates with minor and communist-sympathizing groups.
