The Building Bridges Initiative (BBI) Bill received the backing of 3,188,001 registered voters in Kenya, according to the Independent Electoral and Boundaries Commission (IEBC).
In a statement, however, IEBC chairman Wafula Chebukati revealed that a total of 668,578 Kenyans who appended their signature in support of the BBI Bill were missing from the register of voters.
By January 19, when the draft constitutional bill was allowed to be transmitted to the 47 county assemblies for debate, the electoral commission had verified a total of 1,140,845 signatures.
The Bill is only required, by law, to get the support of at least one million registered voters to be submitted to the county assemblies for debate to be approved or rejected within three months.
By end of Monday, the BBI Constitutional (Amendment) Bill had been passed by 12 county assemblies and rejected by Baringo only after Samburu passed the it overwhelmingly on Monday.
ODM Party Leader Raila Odinga, who is a key proponent of the BBI Bill alongside President Uhuru Kenyatta, has expressed confidence more than 24 assemblies will pass it by Tuesday.
Once the Bill is approved by at least 24 county assemblies, it will be sent to the National Assembly for drafting of the referendum bill that will be taken to Kenyans to approve or reject.
