The details of 31,000 potential voters are missing from the biometric voter registration system, the Independent Electoral and Boundaries Commission has said.
Immaculate Kassait, IEBC's director of voter registration and electoral operations, made the disclosure to members of the Political Parties Liaison Committee yesterday during a tour of the national election centre at the Bomas of Kenya.
The number includes more than 13,000 people with multiple registrations who will not be allowed to vote.
The rest, whose details were not captured by the BVR system and are not registered more than once, will vote based on the manual register of the commission, also called the black book.
The IEBC's principal register has 14,352,545 registered voters, including 2,637 in Uganda, Tanzania, Rwanda and Burundi.
Members of the Political Parties Liaison Committee told the Star that they were pleased with the preparations the IEBC has made ahead of Monday elections.
"It was a familiarisation tour of the tallying centre. We were being taken through the process including the placement of agents. Generally we are satisfied with most of the things including the transmission of results as they have explained," said Franklin Bett, Cord national coordination committee chairman.
Bett's remarks were supported by Ford Kenya deputy executive director Reuben Ameli who said IEBC had assured them of the electronic results transmission system.
Ameli said each party will be required to have one national chief agent, 47 chief agents for each county and 290 constituency chief agents and polling agents.
"The commission has assured us that the election will not run into the second day. The average time taken for each voter is between four and eight minutes and the process will be like a conveyor belt that only stops when there are no more voters on the queue," he said.
Other members of the committee present were Narc Kenya presidential running mate Augustine Lotodo, Cord's Gideon Ndambuki, TNA secretary general Onyango Oloo among others.
At the national tallying centre, each constituency will have a call centre to deal with issues of personnel and other contingencies.
The national tallying centre has been divided into nine categories representing the former provinces and the diaspora voters' desk, said Kassait.
IEBC officials also met with party IT gurus to take them through the transmission system which has caused anxiety among some quarters over its alleged failures.
