Veteran Congress leader Mallikarjun Kharge, who filed his nomination for the post of party president on Friday, said he was fighting for big change in the party.
He also appealed to all delegates to vote for him.
"I thank senior leaders from all states for supporting me in the Congress presidential election," Kharge told reporters at the AICC office after filing his nomination.
His candidature was proposed by party leaders Ashok Gehlot, Digvijaya Singh, Pramod Tiwari, PL Punia, AK Antony, Pawan Kumar Bansal and Mukul Wasnik.
G23 leaders Anand Sharma and Manish Tewari have also backed him.
Kharge is one of the most experienced persons in the party and is a Dalit leader too, Tewari said.
Friday is the last day for filing nominations for the top party post.
