AAP Rajya Sabha MP Sanjay Singh has written to the Union finance secretary seeking sanction to prosecute the Enforcement Directorate chief and the assistant director for allegedly making “false and derogatory claims” against him in connection with the Delhi excise policy case which is being probed by the agency.

Singh’s letter came after the ED filed an application, on April 20, in a court seeking to correct a “typographical/clerical” error related to his name in the charge sheet. ED sources said Singh’s name appears four times in the charge sheet out of which one reference is wrong as his name was typed “inadvertently” in place Rahul Singh’s.

Rahul Singh was Delhi excise commissioner when the policy and formulated.

AAP alleged that Sanjay Singh’s name has been mentioned in the ED charge sheet in the case “at the behest of the PMO” to defame the party and its leaders.

Singh had on April 22 sent a legal notice through his lawyer to ED chief Sanjay Kumar Mishra and Assistant Director Jogender Singh, asking them to issue an apology, or face civil and criminal proceedings.

An ED counsel wrote to Singh’s lawyer on April 29 saying, “Instead of Rahul Singh, Sanjay Singh was inadvertently mentioned at only one reference. The application for correction is much prior to the date of the present notice (Sanjay Singh’s notice to the ED on April 22), which demonstrates the bona fide of the agency,” the ED counsel said.

In a statement issued on Wednesday, AAP said, “Senior leader and Rajya Sabha MP Sanjay Singh has written a letter to the Union Finance Secretary, seeking sanction for prosecuting ED Director Sanjay Kumar Mishra and Assistant Director Jogender Singh.”

“The request has been made to prosecute the officers under Section 499 r/w Section 500 of the Indian Penal Code, 1860, for making defamatory and untrue statements about Sanjay Singh,” the party added.

ED sources said the agency moved a petition before the designated special PMLA court on April 20 to rectify the anomaly in the prosecution complaint (charge sheet) after the “typographical/clerical” error came to notice.

In a video message issued on Wednesday, Singh slammed the agency. “In reply to my legal notice, the ED today has admitted that my name was put in the charge sheet by mistake. What kind of joke is this? What kind of fake probe is this?”

The ED is conducting “a baseless” probe into the alleged scam in the Delhi liquor policy, he alleged.
