In the clip, a man, Mr Barasa claims is Junet, is heard telling a yet-to-be-identified person on the other end of the phone call who seems to be working at the commission that he was ready for the meeting they had been planned earlier.
The person claimed to be the Suna East MP is heard instructing the receiver of the phone call to ensure that they bring on board IEBC chair Wafula Chebukati, himself, and Commissioners Abdi Guliye and Boya Molu to the said meeting.
The said meeting was slated for 6.00 pm and was also supposed to be attended by other persons that had already been agreed on prior to the phone call.
The phone call also featured a "Kisii man and a big man," who were also to be part of the meeting. From the clip, there was an issue that needed to be addressed and done away with.
"Now there is a high-level meeting that you were asking me about I want to organise it tomorrow..... We will discuss his matter and we have to come up with a solution,'' the man claimed to be Junet says
On his Facebook page, Barasa had vowed to expose the Suna East MP's alleged intentions to manipulate the August polls.
He had also threatened to expose the alleged secret meetings and manipulated opinion polls that have placed Azimio presidential candidate Raila Odinga ahead of Deputy President William Ruto.
"We are following you keenly. I will address the nation tomorrow at 4 pm with details and evidence of your attempts to manipulate elections. This will include meetings you've held with pollsters to manipulate opinion polls in favour of Raila Odinga," Barasa said.
Ruto allies have always faulted the opinion polls' arguing that they are fabricated in the leafy suburbs of Nairobi.
During a rally held in Nairobi last week, Garissa Township MP Aden Duale said night meetings are held in the city where individuals are paid to manipulate the polls in favour of Azimio.
"We know where you are manipulating the opinion polls. We even know the office in Runda where you meet. Opinion polls will be on August 9 and Kenyans will decide," he said.
