But Omanga's supporters disputed the results leading to chaos at Nyayo stadium tallying centre.
Shebesh had stormed the premises earlier on Thursday over an alleged plot to rig her out of the Nairobi Jubilee primaries.

Shebesh claims the Embakasi North returning officer cancelled her votes in favour of rival Millicent Omanga.
"I have evidence that the returning officer cancelled votes in favour of Omanga, but I will not leave here unless this is corrected. Otherwise one of us will go to jail," the Nairobi woman representative said.
