India's main opposition Congress party will announce its first non-Gandhi chief in over 24 years, later on Wednesday.
The party held the election on Monday, where 96% of the 9,915 eligible Congress delegates, representing all Indian states and Union territories, cast their votes.
Of the two contenders for the top job in the party, Mallikarjun Kharge, considered close to interim Congress president Sonia Gandhi, is likely to win against Shashi Tharoor.
While 80-year-old Kharge has 50 years of political experience, 66-year-old Tharoor joined the grand old party in 2009 after nearly a 30-year stint in the UN.
