Kamaraj remained Chief Minister for three consecutive terms. Kamaraj noticed that the Congress party was slowly losing its vigor. He came up with a plan which was called the “Kamaraj Plan”.

On October 2, 1963, he resigned from the Tamil Nadu Chief Minister Post. He proposed that all senior Congress leaders should resign from their posts and devote all their energy to the re-vitalization of the Congress.

In 1963 he suggested to Nehru that senior Congress leaders should leave ministerial posts to take up organisational work. This suggestion came to be known as the ‘Kamaraj Plan’, which was designed primarily to dispel from the minds of Congressmen the lure for power, creating in its place a dedicated attachment to the objectives and policies of the organisation. Kamaraj was elected President, Indian National Congress, on October 9, 1963.

Well impressed by the achievements and acumen of Kamraj, Prime Minister Jawaharlal Nehru felt that his services were needed more at the national level. In a swift move he brought Kamaraj to Delhi as the President of the Indian National Congress. Nehru realised that if he had wide learning and vision, Kamaraj possessed enormous common sense and pragmatism.
