Campaign Secretariat chairman Musalia Mudavadi on Sunday claimed that some commissioners of IEBC and Jubilee party officials have been meeting at a house in Kileleshwa to scheme on how to manipulate the Tuesday's election results.
Mudavadi said the opposition will, however, resist strongly all attempts to undermine the credibility of the polls.
"We have evidence that the meeting has been taking place in Kileleshwa. But we warn the commission that it will be held accountable for all malpractices during the elections," Musalia said at a press conference on Sunday evening.
He also asked the commission to ensure that ballot papers are distributed on time.
"We are very disturbed because we know some ballot papers for some Opposition strongholds are still lying in Nairobi, this is unacceptable," Musalia said.
In June, Raila Odinga, NASA's flag bearer, released names of 42 police officers he claimed have been stationed as agents to cause chaos during elections.
The Opposition leader said the officers have been picked from units including GSU, Kenya Airport Police Unit, traffic and the dog unit.
To perform the “special duties”, he said, the officers' kits have been withdrawn.
"The officers have been assigned what the Kenya Police Service calls 'special duties' via a circular dated June 23," he said in a statement.
"They have been issued with clearance certificates and asked to report to headquarters to be issued with discharge certificates before July 2. Their identification cards have been withdrawn.
