Shyam Jaju has been appointed Co-Convenor of the Committee comprising 25 members.
The decision to appoint Malhotra as convenor of the committee was taken by Goel after a discussion on the issue with party's Delhi Election in-charge Nitin Gadkari.
Malhotra, who is leader of the Opposition in the assembly, had decided not to contest the election.
His son Ajay has been fielded by BJP from Greater Kailash from where Malhotra had won in 2008 assembly poll.
