"imperialist" United States and Great Britain, and the "deviationist" and "Stalinist" Soviet Union. At the 22nd Party Congress in November 1962, the left-wing of the JSP revolted, and succeeded in persuading a majority of party members present to adopt an "Eda Vision Criticism Resolution" that renounced the "Eda Vision" as antithetical to core party principles. Eda was forced to resign his position as Secretary General, and thereafter the party returned to a more dogmatically Marxist platform which emphasized the urban working classes as the party's main political base. Thereafter, a younger generation of reform-minded activists became disillusioned and began to drift away from the party. At the same time, the emergence of the "Clean Government Party" (Kōmeitō, the political wing of the Sokka Gakkai Buddhist religious movement) and the increasing electoral success of the Japan Communist Party, began to eat away at the JSP's urban working class base. The Socialists slipped in the polls in the 1967 election, lost more ground in the 1968 Upper House election, and suffered a crushing repudiation in 1969, when they lost 51 seats in the National Diet. 1970s In some regions, the party continued to perform well at the local level and by the 1970s many areas were run by JSP (or JSP-backed) mayors and governors, who supported environmental protection initiatives and introduced new social welfare programs. Meanwhile, Saburō Eda continued his efforts to reform the party and expand its base. Eda ran numerous times for the post of party chairman, but was unsuccessful, although he did serve a second stint as Secretary General from 1968 to 1970. Nevertheless, Eda remained popular among the broader Japanese public and in the mid-1970s conservative prime minister Kakuei Tanaka said at a press conference, "If the Japan Socialist Party were ever to make Eda its Chairman again, a general election would be terrifying. They would drastically expand their seats in the Diet." Eda could never overcome the undying animosity his "Eda Vision" had won him from his party's left-wing. In 1976, Eda lost his reelection bid and was booted from the Diet. Blaming his loss on his party's dogmatic, doctrinaire Marxism and desperate for reform, he attempted to resign from the JSP but the party refused to accept his resignation and voted to expel him instead. The following year, Eda and Hideo Den () led a small group of JSP Dietmembers to split from the JSP and
