The row started after Suresh Nakhua, Spokesperson of the BJP's Mumbai unit, tweeted that Aljo K Joseph, who appeared for the Michel, was national in charge of the legal department of Indian Youth Congress.
Soon after, In-charge of BJP's national Information and Technology department Amit Malviya tweeted: "Meet the Congressman who is going to defend AgustaWestland 'middleman' Christian Michel... Does it get more obvious than that?."
"I am an advocate and appeared in my personal capacity. If somebody asks me to appear on his behalf, I have discharged only my duty as a lawyer. This has nothing to do with Congress. My relationship with Congress is separate and my professional relationship is separate," Joseph said.
