Which party separated from the Congress and became an opposition party?

Congress Socialist Party

During the pre-Independence era, the Congress served as a platform that welcomed numerous groups, interests, and even political parties, allowing them to participate in the national movement. Many organizations and parties, with their own constitutions and organizational structures, coexisted within the Congress. However, some entities, such as the Congress Socialist Party, later chose to separate from the Congress and become opposition parties.

Despite differences in methods, specific programs, and policies, the Congress party managed to contain, if not fully resolve, these internal dissensions and build a consensus. It navigated through diverse viewpoints, aiming to find common ground and maintain unity in the pursuit of its political objectives.
