BJP leader Karan Singh Tanwar on Monday took oath as member and vice-chairman of NDMC on a day the Delhi high court decided to expedite the hearing on a plea of an AAP MLA challenging his appointment. “NDMC Chairman Naresh Kumar administered the oath of faith and allegiance to the Constitution of India to Karan Singh Tanwar who took over as Vice-Chairman and Member of the council in a special meeting today (Monday),” New Delhi Municipal Council (NDMC) spokesperson Jagjivan Bakshi said. Ignoring AAP government’s recommendation, the Centre had nominated Tanwar as the vice-chairman of NDMC through a notification issued on July 8 by the Ministry of Home Affairs. The BJP-led Centre had rejected the name of senior AAP leader Gopal Mohan, recommended by Arvind Kejriwal.
