'Banyan tree' was a symbol associated with which Indian political party during the period after independence?

Socialist Party

The Socialist Party originated during the mass movement stage of the Indian National Congress in the pre-independence era. In 1934, a group of young leaders formed the Congress Socialist Party (CSP) within the Congress, seeking a more radical and egalitarian approach. Despite having a presence in many states, the Socialist Party faced disappointment due to limited electoral success. The Socialists differentiated themselves from both the Congress and the Communists by advocating democratic socialism. They criticized Congress for favouring capitalists and landlords while neglecting workers and peasants. Its symbol was a 'huge banyan tree'.
