The Workers and Peasants Party (WPP) was a political party in India, which worked inside the Indian National Congress 1925-1929. It became an important front organisation for the Communist Party of India and an influential force in the Bombay labour movement. The party was able to muster some success in making alliances with other left elements inside the Congress Party, amongst them Jawaharlal Nehru. However, as the Communist International entered its 'Third Period' phase, the communists deserted the WPP project. The WPP was wound up, as its leadership was arrested by the British authorities in March 1929.
The party was founded in Bengal on 1 November 1925, as the Labour Swaraj Party of the Indian National Congress. The founding leaders of the party were Kazi Nazrul Islam, Hemanta Kumar Sarkar, Qutubuddin Ahmad and Shamsuddin Hussain. The founding manifesto was signed by Kazi Nazrul Islam. During the first three month of existence, the party organisation was very provisional.
At the All Bengal Praja Conference, held at Krishnagar on 6 February 1926, a resolution was moved by Faizuddin Hussian Sahib of Mymensingh for the creation of a workers-peasants party. The move was seconded by Braja Nath Das of Bogra. The resolution was passed by the conference, and in accordance with this decision the name of the party was changed to 'Workers and Peasants Party of Bengal'. Dr. Nares Chandra Sen-Gupta was elected party president and Hemanta Kumar Sarkar and Qutubuddin Ahmad were elected as joint secretaries.
As of 1926, the WPP of Bengal had only 40 members, and its growth in membership was very slow. A two-room party office was set up at 37, Harrison Road, Calcutta. British intelligence perceived that the Bengal Jute Workers Association, the Mymensingh Workers and Peasants Party (with branch in Atia), the Dhakeswari Mill Workers Union, the Bengal Glass Workers Union, the Scavengers' Union of Bengal (with branches in Howrah, Dacca and Mymensingh) and the Workers Protection League were led by the party.
