Putting up a united front, a delegation of 11 parties from the opposition INDIA bloc met the Election Commission on Wednesday to share their concerns over the large-scale revision of the electoral rolls in Bihar, but came out more unhappy than they were when they went in. "After meeting the Election Commission, our concerns have increased further because the Commission did not give a satisfactory reply to any of our questions," CPI(ML) Liberation General Secretary Dipankar Bhattacharya, who went on to call the process 'votebandi', said.
