In a statement send to newsrooms on Wednesday afternoon ODM leader Raila Odinga has alleged massive anomalies in the ongoing mass voter registration exercise.
The statement comes in hours after IEBC gave out figures suggesting that perceived Jubilee strongholds are still leading in the registration of new voters.
"We have unearthed serious anomalies in the on-going voter registration that bring to questions the integrity of the register being compiled and the figures being released by the IEBC," reads Raila's statement in part.
"Our investigation has confirmed that numbers that do not qualify as identity card numbers have been used to register voters in parts of the country and that is responsible for what is being presented as high turnout in voter registration in those regions," it continues.
"A random check shows that the following numbers have been used as national identification cards to register voters. 0 00 1 2 11 12 231 111 20 21, 22 23 24 25 26 27 28 29 40," reads the statement.
The former Prime Minister said they have a list of 8 people who were registered by IEBC using their second identity card.
"We have information that the doctoring of the IEBC registration software was done intentionally by former employees of IEBC who are aligned to Jubilee as a way to ensure Jubilee strongholds register more voters," said Raila.
He further alleged that the doctoring exercise is currently being conducted in homes of senior government officials and in an office of a former Cabinet secretary.
The opposition chief urged IEBC to remain impartial in conducting the exercise.
"The IEBC must come clean on this matter. But not just that. These developments mean the audit and cleaning of the register is mandatory and has to be extremely thorough," said Raila.
IEBC and the government had not yet responded to the claims by the time of going to the press.
