Iqbal has already pledged unconditional support to AAP's Arvind Kejriwal, who was sworn-in as Chief Minister today.
"Being the most senior member in the Assembly, Iqbal is already Pro-tem Speaker. He has been Deputy Speaker in the past and is currently the most senior member in the House.
"The ruling party and the Opposition should build consensus on his name and make him Speaker," JD(U) general secretary Javed Raza told PTI.
JD(U) MP K C Tyagi said AAP coming to power in Delhi is "most unique experiment" in Indian politics since independence and is totally different from the traditional way of politics.
Iqbal has won from Matia Mahal assembly seat, his traditional constituency.
