The organization developed by Mohandas Gandhi's reorganization of the Congress in the years of 1918 to 1920 has largely been retained till today.
In every Indian state and union territory or pradesh, there is a Pradesh Congress Committee, which is the provincial unit of the party, responsible for directing political campaigns at local and state levels and assisting the campaigns for Parliamentary constituencies. Each PCC has a Working Committee of 10-15 key members, and the state president is the leader of the state unit. The Congressmen elected as members of the states legislative assemblies form the Congress Legislature Parties in the various state assemblies, and their chairperson is usually the party's nominee for Chief Ministership.
The All India Congress Committee is formed of delegates sent from the PCCs around the country. The delegates elect various Congress committees, including the Congress Working Committee, which consists of senior party leaders and office bearers, and takes all important executive and political decisions.
The President of the Indian National Congress is in effect the party's national leader, head of the organization, head of the Working Committee and all chief Congress committees, chief spokesman and the Congress choice to become the Prime Minister of India.
