Phibun had failed to win the popular support that he had sought, and the effort cost him what remained of his standing among the military faction. As a result of the election, Phibun formed a new government in March 1957, appointing Phao as interior minister with responsibility for internal security. However, it was Sarit, whose prestige had not been at stake in the election, who as newly named armed forces commander in chief emerged as the strongest member of the ruling group. In September he openly broke with his colleagues, ordered tanks into the streets, and displaced Phibun and Phao in a bloodless coup d'etat. He suspended the constitution and dissolved parliament. The king approved Sarit's action; the royal family had opposed Phibun since the 1930s.
New elections were held in December under an interim civilian government headed by Pote Sarasin, the secretary general of SEATO. No single party won a parliamentary majority, but Sarit organized a government party, the National Socialist Party, to contain the loose coalition of parties and individuals backing his regime. Because of poor health Sarit did not attempt to form a government but turned over responsibility to his deputy in the armed forces, Thanom Kittikachorn. Intraparty wrangling over political and economic spoils plagued Thanom's government. The situation was further aggravated by the inclusion in the government party of left-wing politicians who opposed its proWestern foreign policy.
