New Delhi, March 19: Delhi Chief Minister Arvind Kejriwal has apologized to BJP leader and Union Minister Nitin Gadkari and Congress leader Kapil Sibal for making unverified allegations of corruption against them, a move his rivals reciprocated by withdrawing defamation cases on Monday. Kejriwal’s Deputy Manish Sisodia hinted that the AAP convenor may also say sorry to Union Fince Minister Arun Jaitley, who had filed also a defamation case against the Chief Minister for accusing him of corruption during his tenure as the chairman of the Delhi cricket board. The development came days after Kejriwal regretted having accused Akali Dal leader Bikram Majithia of drug trade without evidence. In a March 16 letter to Gadkari, Kejriwal said he was feeling sorry for making “certain statements, without regard to its verifiability, which seem to have hurt you...”I have nothing persol against you. I regret the same. Let us put the incident behind us and bring the court proceedings to a closure.” He also suggested to the Union Shipping and Transport Minister that “we should put our energy to serve the people of this country in the spirit of mutual respect”. Consequent to the regret, Gadkari and Kejriwal later filed a joint application in the Patiala House Court, seeking withdrawal of the defamation case.
