In the third phase of the Left Movement the Communist party entered in a united front plan with the Anti- Imperialists. Following the deliberative policies of the Seventh Congress of the Communist International, R.P Dutt and Ben Bradley published their thesis entitled The Anti Imperialist People`s Front in India in March 1936. Dutt Bradley labeled the India National Congress as merely the united Front of the Indian people in the nationalist struggle. They advised the communists to join the Indian National Congress, utilize its solid party organizations, strengthen the Left wing of the within the congress and overthrow the reactionary right wing elements. The Communists, the CSP and the Trade unionists planned to organize a Front Populaire on the basis of a common minimum Programme. But the communist leadership however failed to establish a social base of their movement. Hence the popular front of the Leftist movement never came into existence. However the Leftist s leaders had profit from the popular upsurge. In the later half of the 1930 the increasing political activities favored the Communist to strengthen their place in the radical politics.
