A three-time legislator from Hinjili, Patnaik also exhibited optimism about BJD retaining power in the state by winning majority of seats in the assembly election, which are scheduled to take place with lok sabha polls.
After winning the assembly election from Hinjili constituency in 2000, the BJD supremo tasted victory from the same segment in his home district in successive assembly polls held in 2004 and 2009.
This time, Patnaik is likely to face a multi-corner contest. While Congress is yet to name its candidate, BJP has announced Devanand Mohapatra as its choice for the seat and other parties are likely to field their nominees.
