AAP sources said back-channel talks are currently on between the two parties. The bone of contention is believed to have been the number of ]seats the Congress wants to contest in Delhi. Of the seven seats in Delhi, the AAP is not ready to cede more than two to the Congress, the sources said. Since the 2013 Assembly polls in Delhi, the vote share of the AAP and the Congress had oscillated, but the BJP's vote percentage remained the same. In the April 2017 Rajouri Garden bypoll, though the BJP wrested the seat from the AAP, the Congress came second and the AAP candidate lost his deposit.
