Cord leader Raila Odinga says they have credible information that the National Intelligence Service (NIS) is heavily involved in the on-going voter registration drive.
He said NIS aims to influence results in the August 8, general election, same way it did in 2007 and 2013.
According to Odinga, the interference involves taking Biometric Voter Registration (BVR) kits across the borders into Uganda and Ethiopia. He said NIS was also assisting citizens of the two countries to register in a Kenyan election process.
"The agency is also assisting citizens of these neighbouring countries to acquire Kenyan identification documents then helping them cross into Kenya and register as voters,'' said Odinga.
He added that the NIS was also interfering with the voter registration process by having youths whose data were collected through the 'dubious' National Youth Service (NYS) exercise over the last few years and registering them as voters, without their knowledge.
"This NIS-driven process is responsible for the multiple registrations, shared identity cards and many cases of people who are captured as registered when indeed they had never done so.''
In the 2013 elections, Odinga said NIS had its officers absorbed into the ranks of the Independent Electoral and Boundaries Commission (IEBC) as polling clerks, with the sole aim of helping Jubilee government attain a dubious victory.
"In 2007, NIS was deeply involved in ballot stuffing among other irregularities to help the PNU win."
In a statement, Odinga challenge the NIS led by Major-General Philip Wachira Kameru to come clean on the matter and assure the country that it is abandoning its 'disgraceful' involvement in the voter registration.
"It must do this with the full awareness that there will be no country if it does not abandon course it is currently pursuing. Kenyans are not prepared to have the NIS choose for them their next leader again,'' Raila warned, Tuesday.
