Percentage-wise, voters in Puducherry, where Congress-DMK alliance wrested power from AINRC, used the NOTA option the most as compared to the rest of the four states.
According to data collated by the Election Commission till this evening, 1.7 per cent of the total voters (13,240) in Puducherry exercised the option followed by 1.5 per cent in West Bengal where Trinamool Congress has returned to power for a second consecutive term.
In West Bengal, 8,31,836 voters pressed the NOTA button placed as the last option on EVMs.
In Tamil Nadu, where J Jayalalithaa's All India Anna Dravida Munnetra Kazhagam retained power bucking nearly three-decade-old trend, 5,57,888 voters (1.3 per cent) exercised the option.
1,88,978 voters in Assam, where the Bharatiya Janata Party and allies wrested power from Congress, used the option. Percentage-wise, it comes to 1.1 per cent of the total voters who exercised their franchise.
In Kerala, where United Democratic Front lost out to Left Democratic Front, the NOTA users stood at 1,07,106 or 0.5 per cent of the total votes polled.
After the Supreme Court order in September, 2013, the EC had added the NOTA button on the EVMs as the last option on the voting panel. NOTA was exercised by nearly 60 lakh people in the 2014 Lok Sabha polls.
Prior to the apex court order, those not inclined to vote for any candidate had the option of filling what is popularly called form 49-O. But filling the form at the polling station under Rule 49-O of the Conduct of Elections Rules, 1961, compromised the secrecy of the voter.
Supreme Court had, recently refused to direct the Election Commission to hold fresh polls if the majority of the electorate exercised the NOTA option in a constituency.
In September last, NOTA was its own symbol -- a ballot paper with a black cross across it.
