The Independent National Electoral Commission, INEC, has said that over 45 per cent of the total numbers of registered voters have been found to be invalid.
The chairman of INEC, Mahmood Yakubu, made this disclosure on Wednesday in Abuja.
Mahmood also raised fears about security challenges on the election.
The commission maintained that 1,390,519 Permanent Voter Cards are valid, adding that it would continue to clean up the voters’ register.
