After Mukherjee files the nomination papers, Bansal will be his authorised representative.
National Democratic Alliance convenor and Janata Dal-U President Sharad Yadav is the first signatory on one set of nomination papers. Samajwadi Party chief Mulayam Singh Yadav and Bahujan Samaj Party supremo Mayawati have also signed the nomination papers.
As a matter of abundant precaution, each set of nomination papers will have 60 proposers and 60 seconders against 50 proposers and 50 seconders required as per the election rules, sources said.
Bansal parried a question on whether he would appeal to Trinamool Congress chief Mamata Banerjee to support Mukherjee's candidature. "It is not my job at the moment. I cannot say anything at the moment," he said.
Bansal said all formalities required under presidential and vice presidential Elections Act, 1952, will be met while filing Mukherjee's nomination papers.
