"Modi should not be arrogant about power because BJP has only won in Assam, in other four states, they don't even have six seats in total," Surjewala told reporters.
Prime Minister Modi on Thursday said people across India were placing their faith in the Bharatiya Janata Party as the party headed for a win in Assam, grabbed a seat for the first time in Kerala and was set to win over a dozen in West Bengal.
Asked whether Congress vice president Rahul Gandhi was the reason behind the defeat in the assembly polls, Surjewala reiterated that Gandhi was the "undisputed" leader of the party.
"Rahul is an undisputed leader of the party and he will continue to serve it. As far as our defeat is concerned, it is part of politics. Even BJP had to face defeat in several elections after coming to power," he said.
Surjewala asserted that it was "impossible" to finish the Congress.
"The ideology of the Congress party is in the soul of Indians and it is impossible to finish it," he said.
