Praja Socialist Party

The Praja Socialist Party, abbreviated as PSP, was an Indian political party. It was founded in 1952 when the Socialist Party, led by Jayaprakash Narayan, Rambriksh Benipuri, Acharya Narendra Deva and Basawon Singh (Sinha), merged with the Kisan Mazdoor Praja Party led by J. B. Kripalani (former president of the Indian National Congress and a close associate of Jawaharlal Nehru).

The PSP led the cabinet under Pattom A. Thanu Pillai as chief minister of State of Travancore-Cochin from March 1954 to February 1955. In 1955 a faction led by Ram Manohar Lohia broke from the party, reusing the name "Socialist Party". The PSP again came to power in the new state of Kerala under Pattom A. Thanu Pillai from February 1960 to September 1962. In 1960, Kripalani left the party and in 1964, Asoka Mehta joined Congress after his expulsion from the party.

Another section of the party, led by the trade union leader George Fernandes, broke off to join the Samyukta Socialist Party in 1967. In 1972, a section merged with Fernandes's party to become the Socialist Party once more, before becoming part of the Janata coalition in 1977 following the proclamation of Emergency by Indira Gandhi.

Elections
