Taking a jibe at Delhi Chief Minister Arvind Kejriwal, Delhi BJP chief Satish Upadhyay has said that he has now taking U-turn on his favourite tool ‘sting operation’.“Kejriwal has used sting operations to defame several politicians but now his team is questioning the legality of the operation,” said Satish Upadhyay. He was speaking on the recently released audio tapes of Kejriwal’s telephonic conversation. He further argued that the truth of Kejriwal who claims to be practising clean politics, transparency, nationalism and internal democracy and Lokpal, has been exposed. “It is surprising that the party and its leaders who were claiming of exposing corruption by recording and sting operations are now saying that these stings are not acceptable under law when their turn has come,” he added. He also claimed that the audio sting of talk between Kejriwal and former AAP MLA Rajesh Garg has also exposed the politics of dividing society on communal lines by AAP.
