Kericho Senator Aaron Cheruiyot on Sunday claimed that BBI signatures were falsified.
Speaking at Jesus Is Alive Ministries (JIAM), Cheruiyot dismissed the five million signatures purported to have been collected by the Building Bridges Initiative secretariat adding they were obtained from Mpesa shops.
"These five million signs they are talking about are fake, they went to M-Pesa shops, took people's identification cards then signed by themselves, IEBC should publish the sign purported to be collected in the papers for verification," the Senator said.
He further challenged the Independent Electoral and Boundaries Commission (IEBC) to publish the signatures in local dailies once they receive them for people to also verify.
On Friday ODM leader Raila Odinga received 5.2 million signatures collected countrywide to endorse the BBI as the week-long exercise came to a close.
Raila urged IEBC to move with speed and verify the signatures to save time and pave way for a referendum.
The ODM leader said the fact that over 5 million people appended their signatures within a week is an indication that the report is popular among Kenyans.
