They should know that even to become the leader of the opposition more than 50 seats are required."He also attacked the Congress by asserting that the party is contesting at the lowest number of seats despite being in power for very long."One of the special characteristics of this election is that the Congress, which ruled for the longest after independence and has many former ministers and chief ministers is in such a condition that it is fighting on the least number of seats in these elections," said PM Modi.Prime Minister also asserted that he has been continuously working with the single aim of putting right all those things ..
