Cord leader Raila Odinga has reported double registration of his ID number, hours after the Interior ministry said Kalonzo Musyoka lied about a similar occurrence.
Raila said on Thursday that he was surprised to find his ID number listed under another person in the IEBC voter register.
He said IEBC clerks at Gusii Municipal Centre found his ID was registered to a woman by the name Maria Anyango.
"This is the same approach Jubilee used to manipulate the 2013 polls," he said.
Kalonzo, who is Wper leader, Musyoka found that he had been sharing his ID number with a 23-year-old woman. But the IEBC and Interior ministry said the Wiper leader lied about this.

Despite the realisation, Raila reiterated that he will not go to his supporters claiming his victory has been stolen again after the election.
He first said this in February last year, during a strategy meeting with his ODM confidants, where anti-rigging mechanism were discussed.
Apart from running a parallel electronic vote tallying system, he and the Cord team planned to train and deploy party agents to every polling station across the country.
But ODM later said Raila will not accept "results of a rigged election" and accused the electoral commission of scheming to steal the 2017 polls.

Raila tasked the incoming IEBC team with cleaning up the voter register "that Jubilee used to rig in 2013".
“I am urging the team led by Wafula Chebukati to start by cleaning the voters register because it consists of 1.5 million dead voters," he said.
He said outgoing commissioners, led by Issack Hassan, favoured Jubilee during voter registration in the run up to the last general election.

The new IEBC commissioners are set to take office after Uhuru formally appointed them on Wednesday.
The appointment of the seven-member team is expected to rejuvenate an electoral agency.
Raila said his victory in the August 8 poll will be determined by the ongoing mass voter registration.
Noting Cord strongholds have 11 million eligible voters, he encouraged his supporters to ensure they enlist.
"I'm confident that if all eligible voters are registered, I will send President Uhuru Kenyatta home," he said.
The opposition leader spoke as he presided over voter registration campaigns in Kisii and Nyamira counties on Thursday.
He was with Governors John Nyagarama (Nyamira), James Ongwae (Kisii) and Okoth Obado (Migori).
