The electoral agency has said more than 128,000 people share identification details in the voters’ register.
In their first press briefing since taking office last week, Independent Electoral and Boundaries Commission (IEBC) officials, led by chairman Wafula Chebukati, said 128,926 people were found to have the same national identity card or passport numbers in the system.
The admission could resolve the puzzle raised last week by opposition politicians Raila Odinga and Kalonzo Musyoka after they discovered they shared voter details with other Kenyans.
Mr Chebukati told journalists in Nairobi that the problem may have been caused by erroneous data entered by clerks or simply applicants submitting the same details to different IEBC officials for registration.
“From our assessment, this represents 0.8 per cent of registered voters. But the commission is working with the National Registration Bureau to clean up the database as soon as possible,” he said
