The Star can now reveal the number of counties that have transmitted forms 34A from their respective polling stations to the constituency tallying centres.
At the constituency tallying centre, forms 34A are given to the constituency returning officer, who then fills Form 34B before handing it over to returning officer for the presidential election.
The counties include Nyeri, Siaya, Tharaka- Nithi, Uasin Gishu, Vihiga, Kirinyaga, Makueni, Mombasa and Murang'a.
Other are Nyamira, Nyandarua, Kilifi, Kericho, Homabya, Embu, Elegeyo Marakwet, Diaspora, Bungoma and Bomet.
Nyeri, Bomet, Elgeyo Marakwet, Kericho and Uasin Gishu were among the first counties to submit their forms.
There have been several reported challenges and delays experienced in various polling stations, which explains why some are yet to submit half of the results.
As at 0005hrs on August 11, almost all the counties had submitted at least 99.55 per cent of the results. However, Wajir county had only submitted 81.31 per cent.
A total of 46,014 out of 46,229 polling stations had successfully transmitted forms 34A by the time of filing this report.
The electoral agency is expected to announce the final results of the presidential vote within seven days from the voting day.
"Results in the public portal are the same that the commission will use to declare the results," IEBC chairman Wafula Chebukati said.
"Collation of results from 290 constituencies is underway and returning officers will deliver Form 34B afterwards."
