Delhi Chief Minister and AAP convenor Arvind Kejriwal on Wednesday claimed attempts were being made to defame the "most honest party of the country", as he wondered how someone's name can be included in a charge sheet by mistake.

His comments came after AAP Rajya Sabha member Sanjay Singh's letter to the Union finance ministry secretary seeking sanction to prosecute Enforcement Department (ED) Director Sanjay Kumar Mishra and Assistant Director Jogender Singh in connection with allegations made against him in the Delhi excise policy case.
