Nationalist Citizens' Party

With President Ramon Magsaysay's death in 1957, several members of his Nacionalista Party (NP) became dissatisfied with Carlos P. Garcia (Magsaysay's vice president who succeeded him). These members bolted out of the NP and established the Progressive Party, while Recto and Tañada established the Nationalist Citizens' Party, with Recto resigning from the NP and merging with Tañada's Citizens' Party. Tañada would later be reelected to the Senate under the NCP banner in 1965 for the last time.
