The cat-and-mouse game between the Congress and the Aam Aadmi Party (AAP) in Delhi is touching new lows. Recently, when Delhi Chief Minister and AAP leader Arvind Kejriwal asked Delhi citizens to conduct sting operations against corrupt officials and report it through a helpline, a senior Congress leader who also happens to be in-charge of Delhi, doubted if Kejriwal would reject the findings of these stings in the same manner in which he had rejected the sting operation on some of his party members just ahead of the polls.
