Senior Congress leader Manas Bhuniya alleged that the roles of Gupta and Deputy Election Commissioner Sandeep Saxena were not beyond suspicion.
"We are not happy with their roles. They should be removed," he said and also demanded the removal of SPs and DMs of Birbhum and Murshidabad districts.
A group of intellectuals, including retired Supreme Court Justice Asok Ganguly, film actor Soumitro Chatterjee, filmmaker Aparna Sen, poet Sankha Ghosh and Samir Aich, also demanded Gupta's removal.
CPI(M), which has entered into an alliance with Congress, told Chief Election Commissioner Nasim Zaidi, who along with other officials was on a day-long visit to the state to review poll preparedness, that Gupta has "not been discharging his duties properly".
"We have raised our complaint against the CEO. He is in-charge and has not been discharging his duties properly," CPI(M) leader Bikash Ranjan Bhattacharya said.
Party leader Rabin Deb said they have lodged 156 complaints to CEC and CEO but got irrelevant replies from the CEO office.
BJP leader Sidharth Nath Singh also registered his protest with the ECI.
Film actor Soumitro Chatterjee and filmmaker Aparna Sen
were not personally present to meet ECI officials but they had signed a letter which was given to the full bench.
These intellectuals and Bhuniya also lodged a complaint against TMC's Birbhum district president Anubrata Mandal, who has already been censured once and issued showcause notices multiple times by the Commission.
Senior TMC leader Mukul Roy refuted all allegations, claiming that issues were reported only from 0.002 per cent of the booths in which polling was held in the first phase.
"Such allegations are an insult to the people of Bengal who went out to vote. It's an attack on their democratic sentiments," Roy said.
He said the allegations against the CEO are meaningless.
On allegations against partyman Mandal, he defended him saying that he didn't violate any rules.
