"The Congress party is my life, the people of India are my life, and I will fight for the people of India and my party, I will fight with everything I have," Gandhi, 42, said in his first speech after being made officially the No.2 in the party.
He also said a "young and impatient India" is demanding a greater voice and role in decision making and more accountability.
In a speech that touched on the ills of a centralized system of government and on the anger and alienation of the youth, who constitute the mass of the country, Gandhi, speaking in Hindi and English alternatively, said the party "does not focus on leadership development".
The party needs to create 40-50 leaders "who can run the country, not just a state" and also create a similar set of leaders at the state level who can be made chief minister.
