The posters of AAP can be spotted on auto-rickshaws these days in which the party is seen "projecting" Mukhi as BJP's CM candidate against Kejriwal.
"I have sent a legal notice to Kejriwal for misusing my photo without my permission. How can he project me as BJP's CM candidate despite the fact my party is yet to announce the same?," Mukhi said.
BJP veteran Mukhi also said that in legal notice, he sought his views within stipulated time and if Kejriwal fails to answer, he will drag him to court over this "serious issue".
Earlier this month, Delhi BJP had asked Mukhi to take legal action against the Aam Aadmi Party over the issue.
"We have asked him to take cognisance of the matter because AAP is wrongly using his photo. He (Mukhi) should take legal action against the AAP," Delhi BJP chief Satish Upadhyay had said.
