A rift soon developed within the ranks of the promoters between civilian technicians and military officers. As finance minister, Pridi proposed a radical economic plan in 1933, calling for the nationalization of natural resources. This plan was unacceptable to Manopakorn and the more conservative military members in the cabinet. The prime minister closed the National Assembly, in which Pridi had support, and ruled by decree. Accused of being a communist, Pridi fled into exile, but army officers opposing the civilian prime minister's move staged a coup in June 1933 that turned out Manopakorn, restored the National Assembly, and set up a new government headed by Phahon. With sentiment running in his favor, Pridi was permitted to return to Bangkok and was subsequently cleared of the charges against him.
