New Delhi, Feb 11 (ANI): The income tax department has served a notice to Aam Aadmi Party seeking an explanation on charges of receiving funds from dubious sources. The notice was sent a day after the Arvind Kejriwal-led Aam Aadmi Party registered a historic win by winning 67 seats in the 70-member Delhi Assembly, beating major players in the state. Politicos on Wednesday reacted on the same.
