The Building Bridges secretariat is set to present the collected signatures to the IEBC on Thursday at 10 am.
The signatures will be presented to the election body for validation. Notably, the secretariat co-chair Dennis Waweru indicated that internal validation indicated that the signatures were legit
On Tuesday, the Secretariat conducted the verification of the 5.6 million signatures.
The team started the verification exercise on Friday last week. The process was expected to end on Tuesday.
As the verification was going on, another team conducted scanning of the physical signature documents ahead of the presentation to the electoral agency.
While speaking to the press on Wednesday, the team maintained that the referendum bill will not undergo any further changes.
ODM leader Raila Odinga last week received the signatures at Daraja House offices, where he officially closed a five-day nationwide signature collection drive.
The submission of the signatures in essence means the Constitution of Kenya (Amendment) Bill, 2020 is locked and no amendments can be incorporated as being demanded by some quarters led by Deputy President William Ruto.
The development also slams the door on Ruto's calls for consensus-building and, depending on his next steps, might see the country hold a contested referendum.
